'06 G/C check engine light on after spark plug change
Just changed my plugs and cleaned the throttle body. Now the check engine light is on. I thought I read somewhere here about this problem, but can't find it.
Replaced the plugs with the factory NGK plugs and cleaned the T/B from advice from here( remove, clean gently w/ alcohol, remove IAC and clean gently). Light is on solid, runs fine. Tried the key dance, didn't work.
Thought I read somewhere here that this is possible due to the PCM adjusting to the new plugs, and after a few trips, the light going off???
'06 G/C 3.7 v-6 90,000 miles
Thanks in advance
