New to the forum.
I have a problem of a bouncing idle. Watch the video . Basically once it warms up it drops and bounces until you put your foot on the clutch, then it goes up to 1100 rpm This seems to happened after replacement of the clutch master and slave. I also was messing around and cleaning under the hood. Everything seems to be intact. The BAC has been removed and cleaned and it works . The butterflys are clean and free gunk. I checked for vacuum lines they all seem ok . Opened connectors and cleaned them... Any ideas? |
a .wmv file?
|
Windows media player file, yes.
|
Update:
unplugged the clutch pedal switch and now pushing the clutch does nothing to hold the idle steady. Rpm just bounce continuously |
For testing purposes,unplug BAC solenoid(black plug) while idling and post back what happens.

Have you adjusted the throttle position sensor to make sure it was in spec? The clutch switch that you unplugged is a cruise control cancel switch. Have you checked to make sure the cruise control cable is not binding or holding the throttle open slightly? Its one more thing to look into.

I would at least check the tps to ensure its in spec. I've had to adjust it in previous GSL-SE's that I've owned on occasion. Are you positive that there are not any vacuum lines that were knocked loose or any connectors that are not seated properly? Did you check to make sure the throttle cable and cruise control cables are seated properly?

I will check the tps and cables once I get back from NYC in a few days. I need a break from this lol.

Back.
Boriquaguerrero: Yes I have this and following it. mazdaverx713b: Yes TPS checks out. Im looking for hoses cracked or loose or not connected. Although I found the air pump belt is loose but this would have been loose when the car was ok as well so I dont see this as the problem. Drove the car today on the highway with no problems or hesitation. Drives ok. Only occurs when at idle, I had to verify. |
Good news
I was reading this post and it made sense since everything was working before. I remember the PO had said something about having to adjust idle but I never paid attention . I did clean the butterflys. Anyways I lowered the idle down to 875. No more bounce. So what he must have done was raise idle but NOT cleaned the butterflys. Anyways I appreciate the help !
