When im driven my lights dim in and out and my check engine light is on. can anybody help me out

 

Does your battery light come on? I had an alternator problem, whining noise and battery light was on. not check engine light. dunno what that could be. maybe some kinda electrical problem?

 

get the code from the check engine light, that will tell you a lot. check the rescources sticky for the how to.

 

any got got the diy for installtion for the alternator?

 

I went to get my alternator check (it was good)
I went and got O2 sensor. (still the same thing)
One morning it was getting to bad, to the point the that i would put it nutrel
and the batt. would die and the engine cut right off. so i thought of the fusses in the inside. look at them and it was the alternator sensor fuse, it had blow out. when I replace it, everything was nomal.
