Or does it act up more than an OBD1 car? My 94 Z28 would throw SES lights all the time off and on, just like every LT1 (all OBD1) that any of my friends own/have owned...

Just wondering if OBD2 is the same, better, or does it light up even more often?

 

did u ever think something was wrong with it?? never had any problems with my 94. came on once, fixed it........went away.

 

OBD-II has more monitoring functions and trouble codes to go with them. I guess that might make you more apt to get a code, but just like OBD-I, it won't throw a code unless something is detected.

 

AIR pump... always a stupid reason. Same with my friends cars.


Anyway, thanks guys.
