1. Poor gas mileage.
2. Slight pinging (only at 1/8 throttle opening).
3. Spark plug insulators on new plugs are (bleached) WHITE.
The engine is NOT overheating. I did a complete tune up, checked the EGR and it is working fine, replaced all the vacuum lines, and checked the ignition timing. All good. Still pings. I'm stumped. :-(
have the same problem?
