Slight rough running (like slight miss) hot or cold from idle to 4000 rpm. Completely cuts off at 4000 rpm. New idle air control. Cleaned throttle body. Could it be something to do with some sort of split intake system?? 127,000mi. Was running great. Ideas??
4.6L DOHC Lincoln Continental. So I fixed the idle stalling issue. Was bad coil on no. 3. Runs great from idle on up. But, still completely cuts out at 4000 rpm and above?? Any thots?
