Stalling

I have a 98 sunfire, 2.2 liter, A/T, 122k miles. Since we bought the car used 2 years ago, it has stumbled and sometimes acted like it was running out of gas. The problem was very inconsistent. Sometimes it would happen several times a day, or not for a month. It will do this in town or on the highway. There was no engine codes. I checked fuel pressure, replaced fuel filter, replaced wiring harness at fuel pump. None of this helped. Last month codes showed up, P0335( crank sensor circuit malfunction) and P0342( cam sensor circuit low voltage). I replaced both sensors and cleared the codes. It seemed to run ok for a few days, but than it actually stalled on my wife and would not restart. When I showed up to tow it, the car started and drove home fine. The same engine codes keep returning and it is hard starting sometimes now. I replaced the fuel pump relay, but it acts the same. Any ideas?
Do you

I am having the same problem with my pre owned 97 pontiac Sunfire. Mine is a 2.4 liter twin cam engine with 111,500. I also had my crank sensor replaced and I cleaned the throttle body, and I dont think it's a weak ignition spark because the engine runs so soundly. I thought I could check the fuel pressure, and maybe replace the fuel pump, but I dont know if it would help out at all. What do u think?

My car is a Pontiac Bonneville 1998 and it stalls once a week and will not start either a few hours or days later my car will start perfectly fine like nothings wrong. I got my crank and cam sensor fixed and it worked fine for another week and stalled again. I then got my fuel pump replaced and the screen replaced and my gas gage fixed. Most of the time it stalls when I roll up a window. I dont know what to do noone knows whats wrong can you help me?

Wow - I have the same problem.

I deal with Saturn of Belleville because of convenience, decent service, and because I used to own an older Saturn (and it's all GM).

I had this same problem with my Sunfire. Once a month, to about one every couple/few months, it will suddenly start to act like it's out of gas (or I say air or water in the gas tank). It teases that it's going to stall and usually does after acting this way for a while. It will restart with a great deal of reluctance, sometimes the first time, sometimes not for a couple of minutes.

I took it to Saturn a couple times and always it was the same thing - the EGR (Exhaust Gas Recirulation) valve. Finally, September 2006 I had them replace it - pretty pricy. It didn't do the stalling/sputtering thing for almost a year. I thought it was fixed. Sometime early Summer it did it again. I took it to Saturn and they said they took the EGR valve and cleaned it (or something - no charge so I didn't analyze it). Then just last week the same thing - this time Saturn wouldn't help me unless I paid a $42 service charge, so I decided to stop going to Saturn. I didn't want to pay for service for an in-warranty part that was defective for the second time (that's another issue). I think this problem is just something that "happens" - maybe a poor timing belt, who knows. Possibly it could have been a recall issue if it happened to more vehicles.

Point being, I think it's the EGR valve as it fixed it for me for a few months. It just seems there's no permanent fix and also won't cause the car to break down permanently so only an intermittent, hour or two long issue.

MEM!
