Ok maybe not THE hardest, but I believe it could possibly qualify. ICP sensor leaking oil which in turn ruined the wiring harness. The computer is ignoring the ICP totally here, and this is why it was starting and running like this. When the computer ignores the ICP sensor the PCM opens and closes the IPR abruptly, looking at other sensors (CPS, EOT and EBPV) to determine what the ICP should be. Usually it sets it at 700 and 3000~ psi and that's it. I believe this is why it had such an un-stable idle. Got a new sensor and wiring harness and all is well.
