I was getting the engine light coming on, but I think I have fixed the problem, but the light is still on and I want to reset the PCM...
Is it as simple as unhooking the battery or is there a better or correct way to do it?

Thanks,

 

Yep just unhook the battery for 15 minutes or so...

 

you can also pull the feul pump fuse for 15 min

 

unhook the batter and hit the brake for 10 seconds. it's not enough to just disconnect it because there is always power stored up somewhere. Hitting the brakes discharges any power that might be left over anywhere in the car and dumps the CPU.

 

Thanks
