#69 of 306 GOOD GOD HELP ME!!!
Jun 13, 2007 (7:08 am)
I bought a 1995 standard pontiac sunfire off this guy who wanted to get rid of it for a hundred bucks. he said it needed head gaskets on it. i thought hey good deal. i had head gaskets replaced on a toyota camry a few years ago and it was like 500 bucks. I in the end get a car for 600 bucks. Well it turns out that when the headgaskets go, it forces other things to go as well like the radiator and some other junk. I have it sitting in my parking lot. It runs, but I was told I wouldn't know for how long so i just have it there. I need to get it fixed, but does anyone have a main idea on how much it will cost me to get it fixed? Because of the headgaskets water leaks right into the oil. PLEASE HELP!!!!!! I NEED A CAR!!!!!!!!!!!!
#70 of 306 98 Sunfire - Random shuddering..
Jun 13, 2007 (4:55 pm)
I have a 1998 Sunfire 2.2L with 171,000km - all was well with the car until this week. I've started to notice a shudder like the car is missing. I'm having a hard time pin pointing when exactly the car does this since I've noticed it during acceleration and also while cruising at highway speed. It hasn't come close to stalling but keeps missing a beat seeming at random intervals. No engine warning lights at all & no overheating. Haven't noticed any starting issues either. I have noticed that when it's acting up and shuddering/missing I've noticed some loss in power when I put my foot down, it seems to temporarily resolve if i give it lots of gas and gets up into the higher RPM range.
I've been going down the most obvious path to see if I can rectify the problem - new plugs & wires, air filter, fuel injector cleaner. Although I can feel the difference in performance with these new parts and it idles much smoother, the underlying problem is still persisting. I've noticed the fuel filter has the under carrage oil protection gunk on it so I'd say it's been at least 5 years since it's been changed if at all. I made an attempt to change the fuel filter today but the quick release ring won't budge and probably needs a mechanic to cut it off and replace the filter intake elbow also.
I'm almost at the end of my short list of things I can diagnose/fix myself so I thought I'd post my problem before forking out the big bucks to a mechanic. $75 with no gaurentee it's even going to be fixed - who has that kind of money?!

Just reading up on problems with all GM cars caused by radiator and Dex cool coolant (orange stuff) blowing gaskets...leaking etc..
did you check to see what's in your radiator?
google Consumer Affairs GM Dexcool
hundreds of complaints..
one guy says he solved the problem:
M L of San Rafael CA (08/26/06) *WE'VE FIXED THE PROBLEM(S)!!
And while it's irritating to look back and see how much $$ I've needlessly thrown at my '92 K1500 Chevy Blazer, several radiators, head gasket, heater core, trans cooler lines, uptake gaskets, pretty much everything that has come into contact with cooling fluids has either corroded or slowly disintigrated. All due to what turns out to be a basic electrical design flaw at GM.
radiator guy hates Dexcool, suspects that perhaps it's the electrolisis that causes the Dexcool to turn to a jelly goop.
Says the higher the amp reading in the radiator, the more goopy Dexcool seems to be.
My story: The original radiator in my '92 Chevy lasted a good while (hint: older radiators had A LOT more copper in them). The trouble really all started and in a big way, after replacing the original radiator. I did pay the $500.00 for the new GM radiator. (hint: the newer made radiators have little to no copper in them. They are mostly aluminum and steel) Within a couple months, I started having to dump money into my K1500 Blazer, LOTS of it!
When radiator #3 started leaking, I got fed up with my mechanic, who kept saying, it's a high milage vehicle. I should expect this. Not thinking it was even slightly odd that everything seemed to be connected to the cooling system or somehow come into contact with it, even though nearly every repair seemed to require draining the radiator?? So, I looked for the oldest, greasiest, busiest, radiator shop in my area. First thing the guy did, after hearing the list of repairs I'd made, was to drop a probe in the radiator to check for a charge, in other words, electrolysis. An acceptable reading is .03 amps. I was running at .38 amps!! Turning the engine off it would only drop it to .27 amps.
So, he replaced leaking radiator #3, and rechecked it,.. .58 amps!! It went up! He shrugged and said, new one must have even less copper than the last one. I've seen a lot of these GM's with this crap going on. I've been doing this thing that seems to fix this problem. Then an off-duty local cop pulled in with his Blazer, newer than mine. We got to talking, he'd had most of the same problems and this radiator guy fixed it for him 3 years ago, and hadn't had a problem since.
Here's what my guy did...
#1 - Attached three, braided ground cables, randomly to the radiator and the block, and grounded them.
#2 - Then took a piece of copper pipeing aprox 3 long, with the same hollow as the heater-core hose, soddered a copper ground wire to the side of it. Midpoint on the hose running from the radiator to the heatercore, he spliced this small copper pipe into the line using hose clamps. Then using the ground wire he had soddered to it, grounded it to the engine block.
#3 - Drained and refilled the cooling system with DISTILLED water and GREEN coolant. Dexcool in his experance is CRAP, and I quote him. He did all this very quickly, then dropped the probe into the radiator and poof .02 amps! It cost me $100. He has me come in to recheck the amps once a month. And still 6 months later, .02 amps, and no new problems. I was averaging 1 problem per month, a leak here, a suspicious gasket there. Now nothing. So, it seems to me that there are really two problems. One affecting the other. A cooling system grounding problem, electrolysis resulting in corrosion and dissintigration of parts and gaskets. And then Dexcool which is unstable in an electrically charged enviroment and turns to goop. Maybe I'm wrong but my '92 K1500 Blazer now has 212K miles on the original engine
#72 of 306 96 Sunfire hard to start
Jul 09, 2007 (3:52 pm)
Just bought a 96 sunfire with the "big" (4.2?) motor. It won't start without giving it some, or alot of gas pedal. It has died at idle, with the AC off, but seems to keep running if the AC is on. I replaced the TPS, did as a friend suggested and disconnected the battery for a few minutes then reconnected and cycled the gas pedal. And I adjusted the throttle cable in a little. Daughter loves it other than it dying at stop lights. Any ideas?

Well, apparently disconnecting the battery cable for a few minutes did it! Also, driving for a little bit helped. I've driven it for two days now and it starts right up every time.

i bought this car brand new in may of 2003. I have had nothing but problems with this car!!!!!!!! I have had a lot of electrical issues. My wiring harnest was cut in half after i had it for about 8 months. Took it in to get it fixed. Took a week to get it back. Now that I have had more problems and looked under the hood thoroughly myself, the wiring harnest has been taped back together!!!!! Now at 60,000 miles, timing chain stretched which broke the "plastic" guide. Had to replace the guide and the timing chain. IT gets better!! Since the car jumped time. I had to replace ALL 8 intake valves. Everyone of them was bent. Now the car isn't getting any spark!! Now I have to replace the ignition control module. Mind you that GM states that you don't need to change the spark plugs for 100,000 miles....BULLCRAP!!!!! I took mine out and there was nothing left of them!!!! I am very frusterated with this car. i have had nothing but problems. When I went to have the valves replaces, they told me that the HEAD bolts were one time use only and would have to replaced. i believe the whole car is a one time use!!!!!!! Good luck to all of you sunfire owners out there. I would not recommend this vehicle ever. As soon as I get this one running, I am buying a foreign car!!!!!

Oh and to add a few more. I also get the clunking and popping noise in the front end. It also has died several times while turning corners, which really sucks when you go through an intersection!! I have been pulled over for headlights, brake lights, etc.... due to all of the electrical problems. I could honestly keep going on forever!!! Can you tell that this car has really got me upset. Oh and the book value on these cars is horrible. You may as well just throw them away. I still owe 5,000 on mine and it isn't even worth 2500 as a trade in.....?????? K. I am done complaining for now. HEY IF ANYONE HAS ANY SUGGESTIONS TO WHY MY CAR ISN'T GETTING ANY SPARK BEFORE I PAY ANOTH 125.00 FOR AN IGNITION CONTROL MODULE , PLEASE TELL ME. GOD KNOW YOU CAN'T TEST ANY OF THE EXPENSIVE PARTS!!

hi, my name is mike and i have the same car, and the exact same problem. We tried changing out the throttle position sensor and a couple of other things, but like you, I am still lost for an answer. Have you found any solutions yet? If so, I am desperate for them and would appreciate any advice you may lend me.
