Car runs fine when its unplugged but plugged in stumbles constantly, I've search and replace the parts that seem to be a common issue for this(IAC,Cam sensor,TPS,MDI,Mass Air Flow) I'm still getting the problem only thing left to replace is spark plug wires and boots, I plan on doing this anyway but would like a backup plan in case that's not the problem, anything else that could cause an issue like this?
Have you checked all vacuum hoses for leaks? And have you tried leaving the car's battery unplugged for 30 minutes ( to reset the vehicle memory ) ?
Yeah I went to some mechanic shops and had them test for leaks, I've disconnected the battery every time I've installed a new part, seems to crank and cut off immediately, was told that's normal but recently the car wouldn't stay running unless the maf is unplugged, I replaced the cam sensor recently
Good luck finding the issue, I had a similar problem, it was my 02 sensors. Car ran fine with MAF unplugged (got 12 mpg) and misfired with MAF plugged in, code P0300. But I messed with the o2 sensors before the issue. There's a bunch of things to check, best of luck to you sir.
Did you happen to ever figure this out? Mine is doing this as well and I've replaced MAF, IAC, TPS Dizzy. Just got a new crank sensor because that's the only code I have and ordered another TPS because I broke mine.
still working on it however i think the problem is similar to what the previous poster stated, which is an o2 sensor issue i plan on having mine replaced soon and will let you know if that was the issue
Did you ever get the o2 sensor replaced? Issue fixedd?
