why does my check engine light comes on when i accelarate in my 2003 GMC denali
with the air condition on i giver it a good bit of gas the check engine light comes on but
not with the air condition off, Unless i'm going up a hill and gun it and then the check
engine light comes on? i changed the two up stream oxygen sencors, spark plug wires
cleaned the fuel injectors,New air filter.
What is the code for check engine light?
When i had it checked no reading can been found is there a fuse that will not allow the code from being seen if blown?
