The title pretty much explains it.

The problem is, whenever im sitting at an idle, i can be in neutral put my clutch in and nothing changes. However, the second i let it out there is a drastic change in RPM's and most of the time stalls out.

I have been told that it is some sort of fuel issue... I dont really understand why that would be...

The only changes that have been made to my 1993 Ford mustang GT is a complete exhaust, intake, and an underdrive pulley.

I tried searching the forums for other possible threads that would explain this, but found nothing. Please, if anyone knows anything about this "issue" respond to this thread.

Thanks for your help.

 

Something is connecting when you engage the clutch even out of gear, so I'm going with some kind of tranny issue.

 

Maybe The Way Your Clutch Is Adjusted, I Just Read In One Of My Mustang Mags A Quick Way To Tell If Your Clutch Is Adjusted Properly Is. Let The Clutch Out In Nuetral (if You Can) Wait A Bout Ten To Fifteen Sec Then Push The Clutch In Count To Nine And Go Directly For Reverse If It Grinds Its Not Adjusted Right. Dont Know If Thats The Prob But May Help?

 

are you giving ti any gas?i had a 94 cobra kinda doing the same thing.i so, ckeck your mass air sensor.pull it out of the housing and check the sensors for grime.did you happen to clean your k/n filter?some times after cleaning it, it wil leave oilly grime on the sensor.this will not let the car move from a idle if it is really dirty.let me now what you find.

 

Dave, the car isnt hard to get into gear EXCEPT for reverse... and the clutch can come out without engaging the gear right off the bat. It takes a little while.

Boosted and harold, its too dark for me to check it now... i will let you know tommorow when it light out and i can check.

Im also pretty sure its not a tranny issue... I just had the tranny replaced with an upgraded T5 (forget the name for it but its like grand somethin somethin) The car has been doing ever since i got it. I also had a different problem and im not sure if its related:

Whenever at an idle... it sometimes begins to rev and then slow down over and over. I was told this is because the hole in the butterfly valve on the carburator to let in air at an idle was clogged with carbon. I tried working on it today and sprayed the valve with some carb cleaner and it seemed to fix it. HOWEVER, the problem with the clutch is still there.

Now, its not that big of a deal... i just have to flutter the gas everytime i shift out of neutral... but i dont like having issues with my vehicles when i dont understand the problem.


Anyways, will get back to you guys tommorow, thanks for taking the time to help me.
