Recently the 2.4 in my '00 Voyager van has begun to detonate or ping on mid to full throttle acceleration under load. If you back off it stops. The motor has 155K miles on it, and has always run well. It has had regular oil changes and maintenance. It is slightly overdue for plugs and wires. The only reall engine troubles I've had relate to the plug wires cracking and arcing due to heat under the hood. Is this an issue that anyone else has had? Could I be detonating due to carbon buildup? If so, how do I tell this? What else should I be checking?
