The main problem is we have now replaced the Catalytic Converter 2 times now in this care. One time in Dec 2008 and just today. You can be driving the car and all of a sudden it starts to spudder then will shut off, the weird thing is it will start right back up? We had to have the Catalytic Converter replaced this time so it would pass inspection, we were told that since engine light was on and computer said this was the problem it had to be done to pass inspection. Has anyone else out there have problems with 2000 Pontic Sunfire? If you did please let me know what you did to fix this. We are about ready to get rid of this money pit soon. We only drove it about 1200 miles in the last 2 years.

yesterday my 03 sunfire started sounding a bit gurgly when at an idle, to it down the highway and it performed well. At the bottom of the exit ramp heard the gurgly and a bit of a jerky motion will sitting with the brake applied, reached my destination in less then a mile and there was no clearing out the gurgle and the slight jumping it was doing , and yes i could see it in the rpm gauge it almost never bounces , but it was slightly.\r\ngot back in it an hour later and the low idle gurgle and jumping was still there took it back down the highway and performed just fine, same issues at the next exit. took it home and had another person move it for me and it was progressivly worse, had a neighbor look at it and we listened to the engine, sounds fine under the hood, but not in the cab, he suggested that it go on a machine and see if any codes are coming up on it , no dash lights appeared .
decided to move it up on the driveway , which has a slight incline to it and as i was backing it up it stalled out. now it will not start at all , but cranks over like it wants to. i had no choice but to drag it down to an auto shop and have it put on a computer this morning and no codes are coming up on it and no dash lights are coming on, no check engine, oil, etc...it appears from the computer check and my problem guages that it has no issue, but will not start, and yes there is over half a tank in it. not sure where to go next from here ??!!?? the plugs were found to be fouled out and were replaced but still will not turn over.... any ideas?

#252 of 304 2002 Sunfire 2.2L Just won't start???? by alwayszebra

May 05, 2010 (7:05 pm)

I have this 2002 sunfire which was sitting for about 6 months. I put some gas in it as well as some gas tank cleaner stuff. Then I charged the battery because it was dead, and turned it over fine. Got insurance for it about 5 days later and then went to turn it over and nothing, so I checked the battery eye and it was dead. I bought a new battery yesterday and it turned over just fine, I ran it for about 10 minutes and even drove it down the street. I turned it off and 1 minute later turned it back on no problem. I went upstairs for about 45 minutes and came down to go get dinner and nothing, it wouldn't turn over the dash lights were all blinking dully and then I noticed the light switch was on. So I turned it off and turned the switch off and tried again, but I still didn't hear the fuel pump engage nor did the starter click at all. Even if the lights were left on for 45 minutes there is no way in hell the battery should be dead it is brand new. When I turn the key I get nothing at all now. Can someone please help me as I have no idea what to do??????

#254 of 304 1997 Pontiac Sunfire stalls when outside temperature gets to high. by therockatmsu

I have a 1997 Pontiac Sunfire that stalls when the outside temperature gets to high. It is a 2.2L, 5 speed, with 235,000 miles. I have had a computer plugged up and only saw a misfire on the codes. I have replaced all plugs, wires, and coil packs. The engine runs perfect until the temperature outside gets hot, maybe 80 or better. During winter months it is fine and at night also. It is a very strange mystery. When it stalls it trys to keep running but it sounds like a engine that is choking down. When you cut it off and let cool for 10 min or so it will crank and run fine till it warms up again. Any suggestions would be greatly appreciated.

Sounds electrical. Does the car just stall the engine, or cut all power completely? The heats causing an open circuit somewhere. with the high miles, i would check for any engine control relays(i.e ignition, injection, ECU, main) and replace them, fairly cheap. Is the Check Engine light on? Scan it. After that, a possible sensor is breaking down from the heat, take it to a trained professional. worst case is the Engine Control Unit is malfunctioning.

First the battery light, then the abs light, then the gauges going crazy, then the stall, a new battery and 2 good hours before the final shutdown. Is it an ecm or an oxygen solenoid sensor, or should I warm up the bike?

I've had the same problems. Who knows how to do the antitheft key turns? Can it be disabled? How much does it cost. Too cheap to buy a new car.

#258 of 304 Traction off light, ABS and service light coming on by ladyvic

Jul 06, 2010 (12:27 am)

I have an 05 pontiac sunfire with a little over 50,000 miles on it. About a month after I got it, which was at about 5,000 miles, The ABS, Trac light and service light started coming on. Took the car in at least 15 times, the only problem they found was the wheel sensor. Still having the same problem til this day. The car will sometimes sputter or shut off when backing up while turning the wheel. Nobody can seem to find the problem. I'm tired of paying $40.00 each time for diagnostics. Also if I slam on the brakes which happened to me twice, the brakes seem to act like they're not in the right position as I feel it thru the pedal. I don't know what to do anymore about it.. of course the warranty is over... Please help someone
