Hey Guys,
With a ton of help from mxmikie I have a new cylinder head installed in the van. It even runs and drives believe it or not. The thing is I am getting some pinging from the engine under light acceleration, and the idle is very high around 1400 rpm's. If I ground out the test plug to set the timing the idle drops down to 8-900 rpm's as it should. The engine runs great aside from these issues, and I was wondering if you guys could help me figure it out. Anyone able to point me in a direction? I have the static baseline timing set at 5* BTDC as the manual says with the test plug grounded out. The pinging is always there, but when it happens it is under light throttle, not cruising or heavy acceleration. Stock 2.4 litre SOHC with a new head, timing belt, plugs, cap, rotor, wires, etc...
Any help would be much appreciated.
Chris
