My customer had a valve drop on his 2006 Equinox. He asked me to replace his motor with a used one from a reliable used motor and transmission dealer.
After installing the used motor there is a P0300 trouble code. I double checked all my work. I replaced the spark plugs with new AC Delco Iridium OE plugs. The coil pack and plug wires are off of the original motor which had no problems prior.
Can you please give me the cylinder identification and possibly give me a few pointers on where to look next.
have the same problem?
