WTH!?!?
Brand new GM Opti, replaced b/c the one on the car was corroded and I could not turn it by hand, the bearing had 'seized' up....

Now it is hard to start, idles fine once stared. quick blip of throttle and it hesitates.

Code 36 Hi-Res MALF

Harness is original but does not have corrosion.

 

You could have got ahold of a bad one Shon. Hit the connections with some contact cleaner and give it another try. Its
worth a shot.

that will suck major donkey dongs...going to try a new harness, this one is old and has been on/off a good bit and think it might need replacing.

 

Be careful with the pins inside of the opti. They dont always line up with the plug and are easy to bend. Hope the harness change solves the problem. http://www.optisparkharness.com/opti...s/default.aspx
