This one is driving me nuts.
I have been chasing a rough idle and intermittent stall problem
The car would run fine while cold. Good power, no hesitation, steady idle. No cel's. Once at operating temp, temp gauge 1/2 way and stable, it would give the out of gas behavior. No codes. Just acted like it out of gas. Feathering the peddle a bit would bring the rpm up but still sputtering. pull over put it in park and idle is fine, revs up like normal. Put it in drive and hit gas either hard or soft and it dies. Let it cool down and limp it home. Drives just fine while cold so Im thinking it’s the tcs. Replaced tcs and cleaned maf while I was at it. That seemed to do it. I drove for about 3 miles and the sputtering started again. Same symptoms. No Codes! Let it cool down limp home. I cleaned throttle body, IAC valve, checked everywhere for vac leaks. Cleaned pvc valve. Ran it several times trying to get a code but none present or logged. Took it for a test drive and it ran fine. Drove 30 miles and no problems. Sweeeet.
Stopped at gas station filler er up and started sputtering and died. Same behavior. I remember when I first noticed a rough idle the fuel tank was ¾ full and only began acting normally AFTER I had less than ½ a tank.
Charcoal canister or purge valve seems likely but both parts are expensive. Anyone have this happen can verify for me?
