Hey all, having an issue which just cropped up in the last week and a half or so. When up to temp sitting at a stop light the car stumbles a bit. RPM drops for a sec, once I hit the throttle its fine. Also, when cruising in OD at 1500 rpm the car does the same thing. If I push on the gas enough to shift into 3rd, RPM comes up and is fine and if in OD above 1500 no issues. Last weekend I had the car scanned and its not throwing any codes. Any idea where to look first? Thanks.

 

clean the iac passage and t/b mabey?

 

Right on, I'll give that a shot.
