Symptoms:
Runs very rich when hot/cold.
Runs rough only when cold.
So far I've put in a working O2 sensor, tested fuel pressure, had a smoke test done, cleaned the idle control valve and tested the coolant temperature sensor. The only thing I can think of is perhaps the CTS wire isn't reaching the ECU. Is this possible/testable?
I'm going to run through the Bentley manual tests soon but I was wondering if there was a test or two that seems to fit my problems.
Thanks.
