hey im a noob.. YAY ... but anyways im trying to learn a lot from this website and i have already... so thanx for the help... but i have a question ... wat the hell is an obd1 and an obd2.. and some one else was talking bout a p28 or something like that.. if someone could tell me wat these things are that would be great... thanx..

 

obd stands for on board diagnostics, the 0 1 and 2 refer to the generations.
0 is 91 and back, 1 is 92-95, 2a is 96-98 and 2b is 99-00 and i think up not sure on the 02 and up. a p28 is an obd1 ecu.

 

And an ecu is the engine's computer.
