check idle stab. control. when my car had a similar problem , unplugging it
worked temporarly, however engine runs at 1200 + rpm.

spark plugs, and compression good. ? check fuel distro plate movement ?

Don't know the exacts of your car, but if its a similar 5 cyl as I have,
those are some places to start, hopefully someone can help you more than I .

Already did the idle stab control.. that is the big roung thing with 2
outlets on the front of the engine in front of the intake correct? I
replaced it as the engine had been racing up the 2000 rpm and then
dropping back to 1000.. bouncing up and down.. so i changed the idle
stabalizer... Today it began running at about 1100-1200 rpm...
yesterday 500, today 1000... I am going to check the fuel and air
filters this weekend.. and i will check the timing again. What would i
specifically want to chk on the plate movement? just make sure it's
not stuck i suppose. will do, thanks again!
