Considering that you've posted twice to the thread since I moved it, you're obviously having no trouble finding it in the new forum, and the purpose of moving the thread to the appropriate forum is so that other forum members, familiar with the vehicle can find the thread and assist you.

Oh - I haven't sent you to any sites - you probably clicked on a link, that took you there - be patient, either Bex, or xxx will respond to you, now that I have moved the post.

When you start your car from cold, it should rev to about 2000 rpm or so, drop about 500 rpm to 1500 rpm in about 5-10 seconds as the throttle opener closes, and then sloely drop to 800 rpm warm idle. You seem to advise that your car is doing this, right? You need to first confirm that the car is timed and tuned properly - a compression test, done with the gas pedal to the floor as you are cranking, will confirm your timing (post your results). Plugs should be gapped to .028", and not used out of the box. What are the condition of the plugs? Have you ever changed the o2 sensor on the car - it is a service point at 100,000 miles, and fails lean (making the car run very rich) when it's failing. Is your check engine light on with the key on, and off once the car starts??

Thanks for replying Mechanic says he checked compression and it was great. Plugs and wires cap and rotor all new plugs Gagged to 28. 02 sensor has not been checked. When I start the car it runs at 2000-2200 then only after it warms to 180 it drops back to 900-1000 and stays there.Runs very rich smokes alot at Idel car gets about 8-10 miles to the Gallon oh Timing was set 8 btdc thats where Iam at I hope I gave you the info you need to help me thanks. one last thing cel is on with key and off when engine is started.
