hello, i am getting a cel # 6. i was told that was the coolant temp. so i was wondering, would that disable vtec? at first when it showed up, the first hour the vtec engaged. and about 4 hours later after i got off work, vtec didnt engage.
and also, to fix this, i would need to switch the temp switch and thermostat right? any other problems i need to look into?
