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?
