Yeah i have the 4 wire o2 sensor for the p28, how can you tell a p28 is for auto or manual are there any numbers or marking that designate it?
The first p28 that mike gave me throws the cel instantly when the key is turned on and the code that kept coming up was #9.
So mike got me another P28 and i pluged it in and no codes on the new one.

Thanks for callin chris....lol yeah oops!!!
