Having some chugging issues (all fixed!) March 18, 2005, 11:09:02 PM My car (87 3.8 bird w/ aod) will sometimes surge when maintaining speed on flat sections of highway. It seems to be the transmission by the way it's feels, but could also be the motor. Sometimes it will also just die when I come to a stop. Today it almost died when I slowed down to take a corner and then accelerated into the turn. It just seems like the transmission is sticking in gear or the engine is flooding out or something. It just started doing this recently. I'm lost here and could use some advice to diagnose the problem. Quote Selected

Or does it do it at any speed?QuoteSometimes it will also just die when I come to a stop.

Re: Having some chugging issues Reply #2 – March 19, 2005, 10:32:41 AM just as a quick test, with the car at operating temperature, unplug the IAC, and see if it stalls out, it not, then its probably not your problem, or at least its least likely the problem Quote Selected
Re: Having some chugging issues Reply #3 – March 19, 2005, 02:09:13 PM It will want to die around any speed when I try to maintain speed, when the pedal is pushed slightly. If I mash the gas, it takes off fine. If I let it idle, it idles fine. It just doesn't like the in between.Okay, I know about the TPS and vacuum lines, but what exactly is the IAC?I changed the Plugs, cap, rotor, wires and everything when I got it about 8 months ago. Is there some kind of vacuum issue? I did just swap out the throttle body, but it ran fine for a couple weeks and just suddenly started doing this after that. Quote Selected
Re: Having some chugging issues Reply #4 – March 19, 2005, 07:22:57 PM I swapped out the TPS with the original one I had lying around. Seems to have fixed the problem. Thanks guys! Quote Selected
