I have a 302 in my 86 Ford F150 that runs great under load and at speed, but has a miss while idling. The motor is in excellent condition with about 10,000 miles on a complete overhaul. Here is what I have done so far:
Anyone have any ideas?
- New plug wires
- New plugs
- new cap and rotor
- stock rebuild other than mild porting to remove emission humps
- shorty headers
- Added heat shields to plug boots due to headers (misses with and without the shields)
- Scanned for codes, but found none
Anyone have any ideas?
