Ok here is the problem. On May 6, I bought a 1994 ES Talon with the 2.0l 4g63 motor. It has 65k on it, and is in very good condition. About one week ago, the check engine light went on, and when at an idle the rpms jump about 300-700, and when the clutch is in or when not in gear (slowing down) the same surge appears.
I connected an ohm meter to the data port and came up with a code 43. Which is for the egr system. I tested the thermo valve sensors, all working. I test the vacum to it, good. I figured all that is left is the egr valve. I removed the valve, and it was fauled bad, alot of carbon deposits. I used carb cleaner and a wire brush to clean it. I then vacum checked the valve. It seemed to be working.
At this point I thought every thing should be fine. I put the valve back in and started the car. It was fine. But after a 10 min drive later that day, it started again, but this time with no check engine light.
I have checked every sensor under the hood twice with the ohm meter and still can't find another problem.
Does anyone have a suggestion?????
Any help will be appreciated!!!!! Thank you Philip
