Runs Great Cold Then

I Have A 1994 Taurus sho And Been Having A Issue That Is Driving Me Nuts,When I Start It In The Morning Perfect Nothing Wrong,Then When it Warms Up It Starts Pulsating(Like A 1000 Rpm To 400Rpm)just as an example so YOu Can See The Rythem.And When I Shut It Down It Doesnt Want To Start Back Up,Unless I hold the gas pedal to the floor,but once it cools down everything is perfect,and starts right up..

Waterpump leaking onto the crank sensor maybe?

 

[rubydist]

Are there any codes?

 

[itwonder]

I'd start with the idle reset procedure, run KOER and KOEO tests, and check codes. Then I would clean and inspect the IAC. Is there any misfiring or roughness associated with this?

 

[matty]

ill check those,the water pump has been done front 60k plus clutch and rod bearings.

Unfortunately, you can't completely rule out a WP or CPS after doing a 60K. I had a Cardone WP that was installed during a 60K fail after 200 miles.
