Not sure if this is the right place lol, but...

It's not that big of a problem but we're told it will get worse.

I have a 98' Mustang GT and it it idles at very low RPM which is normal in most cases, but also when you are in 4th or 5th gear, even 3rd, and running at 2500 RPM and and hit the clutch to stop it will stall out, now to combat this i've learned to pump the throttle right after i press the clutch to prevent it from stalling out. Anyone know what this could be?

 

possible IAC issues...

it is notorious for causing idle issues. You can try cleaning/replacing it.

 

if its not that what else could it be?

 

if i replace the MAF where would i dyno tune it? because im thinking that replacing it and getting a new intake might solve the stalling problem, and maybe the IAC could fix the idling issue, how would i clean the IAC?

 

look in the stickies. you can clean your maf also.
