Hey guys.
Here's my problem couple days ago i was driving from my work to my sweet home (40 mins drive)
and when i took my last corner to pull up to my house i felt like my car is about to stall (i was in neutral - speed about 25)
i saw my RPM's went down from 900 to like 500-400 than went back up, i was like well fixed by itself.
So today i went to my gf's house it was doing it almost every 10 mins (Only when hot) so,
this night i'm going in my car to start driving from my girls house to home ,
I'm starting car , flooring clutch , putting it in gear , turning my wheel to drive, BAM it stalled :@ (COLD)
so now it got even worst , everytime at idle , or when i'm staying on traffic light, my RPM jumping from 900 to 300-400, and even sometimes all lights coming on for less then a sec (oil, battery , etc. etc.) like it stalled but then goes back to 900 rpm's :@
what you think guys could be the problem??? TPS?? maybe dirty cai can cause this??? upstream oxygen sensor???
or maybe i got feeling that it's somehow doing it because of clutch (pressure disk),
cause everytime i'm pressing clutch something squeze inside of trans :@
what else i dunno??
P'S NO CEL came on , not even once GRRR

I bet your spark plugs need to be cleaned or changed. Sounds like what happens to me.

everyone allways blames the TPS for everything that goes wrong on these cars, but i think for once, it will actually be the TPS lol. it does sound like a bad TPS though

LOL

We don't blame everything on it, but the plethora of problems I had when mine went tits up, covers a LOT of these folks drivability/idling problems. Since it's a free fix, get it fixed, and if it's not the TPS, you can narrow it down.
