Engine Performance problem
1985 Ford Mustang V8 Two Wheel Drive Automatic 175635 miles
why is my timing when I checked it, advance to approx 28 degrees at about 2000 rpm, then retard to 12 by 3000rpm? I just purchased the car and noticed it will get weak under full throttle after about 2500 rpm and stop pulling by 4000. It's currently set at about 14 degrees at idle. The plugs say lean condition, and it seems to be thru out the rpm range. What should I look at first?
Sorry. Let me clearify. This is a 85 5.0 CFI intake, electrically controlled timing. Guessing this is a control issue. Thinking along the lines of o/2 sensor. I've checked my plugs after a short drive and after a long hard pull with emmediate shut down and check and have found the plugs to be showing lean condition. Little short on money after this purchase and am looking for help thru the net so as to work out a game plan of attack on this issue.
A lean condition from idle all the way thru red line seems to be the issue causing the computer to pull timing after 2000 rpm. I appreciate the ansmer to my question. Felt I needed a little clearification on my engine type. Sorry for the lack of info.
have the same problem?
