First off I did a search and couldn't find anything associated to my exact issue. Maybe someone can help?
I have a '99 SE 5 sp. w/ 165k.
When first starting the car cold the rpms rev high to 2k and higher. When they get to about 2200 the car then drops to 1500 and slowly up to 2200. Once the car warms to normal temp it seems to run close to normal.
I have removed and cleaned the following, replacing the gaskets in the process:
The TPS was tested and adjusted by the dealer when i had another issue fixed (leaking intake manifold gasket replaced). So, I don't think it's the TPS.
Also, I said 'close to normal' when driving. Every time I push in the clutch to slow to a stop the rpms will sit at about 1500 then fall to about 600-800 rpms. And while driving, the accelerator is touchy when starting to depress it making the car jumpy.
This is starting to drive me nuts.
