again, that would be consistent, this is intermittent. I've pulled the code in the recent past, and have gone through many tanks.

Thats highly improbable.

I should mention that thats 6K I have put on the car, its an 01 AP1 with 124K on it.

Could a cam position sensor cause this? Could it have gotten damaged against the firewall when the motor was lowered to let the transmission out?

Freeze data is the PCM recorded data similar to Data list. anyways, i would go ahead to check the valve lash, than do an Induction service (often called Top engine clean) to see if it shows improvement.

Yeah check the TDC sensors on the valve cover.

By the way try the MAP whack. My friend had the same issue and bought a bunch of stuff and the MAP was the culprit.

Search map whack

It could. It fixed my friends. He changed his O2... same, he changed the plugs... the same... refilled the gas... the same... we were going to swap coil packs but he decided to try the map whack and he's been trouble free since.

We tried a brand new MAP already and it did not fix it.
