Normally, with the car warm, on occasions, when I start the car.. as soon as I remove my foot from the clutch, the RPM's drop to about 200 and then back up to operating temp.

Now, I haven't started the car in about two days.. on today's cold start, the same thing happened. After releasing the clutch and hearing a click (clutch release right?), the rpm's went up as normal to 2k and dropped immediately to 150, huddled a bit, and then back to 2k, and proceed to warm up like a baby.

Only thing I can think of is a possibly bad IACV. Any ideas?

I'll get a video soon! Maybe tonight after the gym.

Thanks guys

 

Ive been searching also. I see some instances of this coming from the MAP. I
ll give that a try before cleaning the IACV.

 

I have the same problem.. could be the maf or spark plugs or bad coil mabe.. i too need to check them out...

 

same issue for me, start run for a few seconds then almost die like on it las turn then kickss back to 15-2k rpm then run good the rest of the day . I think I read some thing the computer rembers the way you drive say when u are coming 2 a stop in second gear and you get to less 15mph then shift to netural your rms go way down to almost stall

 

I haven't yet changed the plugs, but I will tomorrow. I'll also try the MAP whack though i doubt that's the culprit.

I didn't know the ecu remembers stuff like that.. thought it just needed a reset after mods like cai and such to retrain/remember driving habits. I'll have to do some more searching. I'll let you guys know how that goes and if anything I try fixes it.

 

for sure let us kno ^_^
