sorry I was looking at OBDI codes.
sticking pedal? you mean when you press it, it stays there for a while?
Iddle air control may be the problem but many other things
can turn the IAC light on.
did you turn the cap in the throttle body and clean inside. it's very important.
anyway it is on the passenger side of the intake manifold. to the right
of the first cylinder intake. you will see 3 little cylinders. one of them is hex sided.
the other two all round. there are 4 screws that hold the IAC to the intake manifold.
there are two small hoses(coolant) entering one of the cylinders. you will have to drain
your coolant to take the IAC out. it is kind of a pain to get the 4 screws. once you
take it out you will see a metal pintle which will be covered with carbon most likely.
carefully clean the carb residue with carb cleaner.
before you take it out you need to disconnect power from the IAC. RPM should drop
immidietly. if they don't then something is wrong with IAC.
check your EGR push it from the bottom. the plate in the bottom should move freely.
you can check resistance of those parts. but I don't remember the correct AMPs.
this is complete manual with instructions for everything.
