#186 of 306 2001 Pontiac Sunfire 2.2l won't start
Feb 25, 2009 (5:47 am)
I need some help.
My son has a 2001 Pontiac Sunfire. The car worked great up until about a month ago. He started having problems where the car would start to lose power and stall when he was going slow or at a stop light. I am in Canada and we thought that maby his gas was freezing up so we put some methalhydrate in his gas tank. It helped for about a week then it started doing the same thing again.
We decided to change that battery as the car got so when it did not start he would require a boost. That helped for about another week.
Now even with the new battery and a boost we can not get his car running at all. The odd time with a boost my husband can get it started but it will not keep going then it just will not start again with a boost.
He borrowed a error code reading machine from a friend but the car is not putting out any codes. He has tested the battery conections. Does anyone have a solution for our problem it is getting annoying. My husband is mechanicaly inclined but everything he checks appears fine. Does anyone have any suggestions please.

Don't let me get started with my sunfire. I have a 96 sunfire 2.2 engine I replaced the alternator 5 times since I bought it in 2001. Mine did the same thing every time (lights dimming, all lights coming on.) I asked my Mechanic why and he said these cars are known to go through alternators. Also These cars and the Cavaliers, BonnieVille, grand am, and the grand prix are all known to have problems with the blower motor resistors going out. I have a sunfire, brother has a cavalier, two friends with cavalier, and one friend with a grand prix. All of us had same problem. The heat started going out one setting at a time. Till finally #4 went out and the heat/ac would not come on. If it ever happens to you, you can repair it yourself. you need a 5/8 or 5/5 socket and a ratchet and ext. a swivel would be better. Drop the blower motor out and right behind it you will find the resistor, remove the two bolts and pop new one in. I'm sick of mine, in the last month I put new ball joint driver side, new brakes & rotors in front, new caliper passenger, new trans mount, cv boot, rear struts, now I need new motor mounts, omg what else.

#191 of 306 2000 Pontiac 2.4 is missing when I accelerate- especially going up a hill
Mar 03, 2009 (3:26 pm)
So, I guess I am a part of this club Anyway, my car has 160,000 miles on it, had been running just fine, but over the past few weeks it has started missing/stalling while I drive, I haven't had any trouble starting it and it's not completely shut-down on me... yet. No check engine lights coming on. The fuel filter has been replaced, the spark plugs have been replaced, and I've ran Sea Foam through the thing, all to no avail, I've got it in a shop and guess what? You guessed right, they're not coming up with anything yet. At first they thought it was the ignition tower, after fooling around with that it didn't make it any better. I'm getting ready to pull my hair out , and I hate that feeling you know, so I beg of you, do any of y'all have any suggestions? I truly appreciate it!

This may be a solution. I have a 1996 Sunfire, 2.4L, manual transmission. Although it never stalled it would buck and hesitate when trying to accelerate. Turns out the ignition coil went bad. The spark plug could be seen arcing with the cover off. The brand new replacement was bad, as was the brand new replacement after that. The one from the salvage yard is working fine and the only problem with acceleration is the manual transmission with 133,700 miles on it.

When you had the spark plugs replaced, did you do them yourself? If you replaced them yourself, did you gap them? These cars use platinum spark plugs , which are usually about $6.25 each. They are supposed to be gapped already but don't rely on that. I bought a set that wasn't gapped. Get a gapper, usually about $1.00. take each spark plug out one at a time and REMOVE ONLY 1 WIRE AT A TIME. if they are gapped to big slighty tap the plug, hook side down on a hard , clean surface. Then run it through the gapper till it's where it needs to be. (repeat tapping if you have to)
If i'm not mistaken the gap should be 0.85 but don't quote me on that. Check each plug Check under the hood for the gap settings for the spark plug. If you cannot find it call autozone, murray's , pep boys or your local mechanic and ask for the gap settings for 2000 pontiac sunfire 2.4 engine.
If you replaced the wires, did you replace them one at a time, starting with the longest? Always start with longest to shortest and one at a time. Did you strip the hole the spark plug goes into. If you did, you will have to take it to a mechanic and have that hole rethreaded. I stripped mine and my car did the same thing hard to accelrate up hill I had to smash the pedal to the floor.
I got curious and checked the plugs , come to find out, I stripped the hole. Sounds to me like it is missing because of either the wires or the plugs. If you replaced the wires yourself(no mechanic involved) you should double check them and make sure you have them from longest to shortest comming from the spark plug hole to the coil. If they are off even one wire, that can cause missfiring and hesistation. If the spark plugs aren't gapped right or even if one is off, it can cause your symptoms too.
Is your airfilter hose attached tightly? Check to make sure that is clamped down to the airfilter housing next to the battery(on my 1996 sunfire it's next to battery). I hope some of this helps sorry so in-dept but I like to help if I can.

After my husband spent about 2 weeks chasing the problem it turned out to be a wire. Apparently because the computer is located up under the front right inner fender it is a common problem in this car where if you hit say a snow bank or whatever it damages the inner fender and can leave the computer exposed to the weather and in turn causes corusin to the wires
So when he removed the inner fender to get to the computer he tested the wires and on our sons car it turned out that there was a orange wire running to the computer that was corroded he simply cut a piece of the wire put it back together and the car has worked great since.
How his problem started was at first it would not idle - then it would stall - and was real slugglish. Most of the lights on the dash would come on - then eventually it would not go at all.

Thank you both so much for your help! I am going to the mechanic with this and I'll keep the board posted on what I find out. Luckily for me the mechanic is getting pissed off at the problem and won't stop until he figures out what is wrong with it! He's also very reasonable, so I hoping this won't cost too much!
Thanks again y'all!
