I just recently got my 04 wrx tuned at topspeed. I was the super late friday night appointment, sorry once again. Anyways the car runs great and pulls hard and smooth. I was just wondering however sometimes when i push the clutch in when coming to a stop light or sign the car will idle down very low and then jump back up to normal idle rpm's. The car will sometimes even cut off and i will have to re crank it or pop the clutch and jump it. At first i thought it was because i had very little fuel but then i put 3/4ths a tank in it and it still does it probably 1 out of every third time i have to stop on the road. Just wondering if you knew something else that could be causing it. Thanks again for the great tune. Taylor
this used to happen on an old jeep I had. And then on my friend's pontiac, and then on my old forester. All three times it was a crank sensor...? So maybe it's that? Sorry, I know I'm not scott. Hope this helps.
Thanks for the info. It didnt do that untill after it got tuned at topspeed so i don't think thats the problem unless it went bad in that particular time period.
I didn't do much with your idle... Make sure all your hose clamps are tight. In the future, if you need anything feel free to e-mail, call, text, or PM. Posting in a general forum doesn't notify me... I end up getting calls that somebody is trying to reach me... Thanks, Scott
battery is new. Also, has grounding 'mod'. Oh wait, we are diag'ing the OP's car. yeah, check those...but i doubt its the problem.
