O2 sensor. it really could be almost anything. loose dizzy will do that too. sounds to me like your rpms are still a bit high when at low idle.

 

have you run the ecu diagnostics yet?

No. You can unplug the O2 sensor while it's running and it won't do anything but run on a pre-set table of values for fuel injection operation instead of using the O2 sensor for mixture/richness feedback. Been there, done that.

ECU wont do anything cause the computer from 95 pathy down doesnt keep the history of systeme problems...resets itself. Which is why im guessing it runs fine after i turn her off for 10 min

Have you even TRIED to run the codes?

 

By the way, the ECU does store error codes...particularly the ones that make it run in Safe mode. It will record and store the codes until you disconnect the battery or the ECU.

Alright alright, my mechanic is a godsent and found the issue. Had nothing to do with sensors or anything of that sort, the sensors where just doing their job lol hehe. Apparently its the engine not holding the vacuum, has to change some gaskets... if its the head gasket its easy.... but the bottom one might be pricy due to labour.

 

Thanks for all your help guys!

 

Jason :wacko:

sssh the head gasket is the lowest major gasket you can change. below that is just yer water pump, rear main seal etc.... head gaskets are easy if you've done it...expensive if you pay someone else to do it.

you have to take a lot of crap off to get to the heads, so it's time consuming. if they charge by the hour expect to works some o/t to pay for it. ;)

good luck and i really hope it's nothing that serious! have them check all your vaccum lines first
