RPM's hang returning to idle.
I have started experiencing the weirdest issue i have ever seen and I have no idea what it is.
If I rev the engine, even blip the throttle past 1200 rpm just slightly, on the way back down the rpm's would hang at 1200 for 3 seconds and then drop to normal idle. If I am in gear, slowing down, force the rpm's down below 1200 rpm and get off the clutch, they will bounce back up to 1200 for 3 seconds and then come down to normal idle. At first I thought it was my throttle cable getting caught, but thats not it. I thought maybe the IAC but it responds properly to the AC turning on and the fans. I am completely baffled. It started happening just out of the blue. |
You could try adjusting your dashpot. It will have a similar effect if adjusted out too much. Although it wouldn't really explain why your idle would just back up to 1200rpm. Something to check out, mine had a similar issue (Link) until I backed off the dashpot.

I should have probably mentioned that I dont use MS for idle.

does it happen if the idle valve is disconnected?

Unless you want to tell me that if I disconnect it and the symptom stops then my IAC is acting up.

I have the same thing and I like it. I find that it helps me in stop and go traffic. it helps with the engine not to bog down. I thought I had a stuck cable too but it seems to be normal behavior.
I will agree that this is an inadvertent benefit which is why it doesnt bother me that much. Still strange though. |
