Rpm issue
I have a 03 gt thats stock beside flowmasters. The problem is when I shift the rpms wont drop for about 2-5 seconds after I have pressed the clutch in. I havent been able to find an vac. leaks. It only does it while driving. I can rev the engine while parked or stopped and the rpms go down fine. Any clue on what this is?

almost sounds normal to me? 1-2s before it starts dopping, 3-4s before it goes under 2k if you shift at 4-5k. but then again, if it takes that long when you shift at 2-3k then yeah, sounds fishy. I suppose it could be a sticky IAC valve... but i dont know why it would work under no load. has it always done this? (i ask because) i have a spacer plate installed between my throttlebody and my IAC valve and it has screws where i can adjust it to control a vacuum leak which causes the car to do what your's is doing... but i bought that and put it in... |
Ummm yeah, shot in the dark but your clutch could be goin bad. Had any other issues with it? Or do you ride the clutch when not shiftin?

If it's stock clutch than it's about time. Replacement is usually needed between 50-70k miles depending on how you drive it.

It sounds to me like a normal issue that a lot of stangs have. You could try a IAC restrictor plate that usually makes the rpms shoot right down as soon as you press the clutch in. Mine did this before and as soon as i bought the IAC restrictor it changed it immediately. I would say do that first b4 you start going into replacing a clutch.
