BadAndy said:

the pinning happens more from a load on the motor and timming at 11 or more

Did you reset the computer after you cleaned it?? If not, definately do so. The KAM needs to be cleared after any sensor changes are made, so the computer can start from scratch, learning the new sensor. (disconnect neg terminal from battery and hold brake pedal for 30 seconds).

Definately clean the IAT and make sure it's indexed, so air can flow through the element, not the plastic u-shaped thing that partially covers the sensor.

If it's pinging at part throttle, and resetting the KAM does not work, you likely have a O2 problem. I would take the torch to them and see if it helps. As O2's age, the actual a/f ratio gets leaner and leaner, even though the comp thinks it's fine.

The EGR could be another thing to check out. It works only at part throttle.
