Before removing the 3800SC / Automatic 4t65e-HD from a 1997 Riviera, I checked for codes. The car always started perfect but had NO Power. Now the engine is completely rebuilt, EXCEPT for the sensors. So maybe these codes will say which ones I need to replace. U480 menu 1.DTC DTC 02 IM no fault 01 pend 01 PO 305 01/02 Anyone ? Thanks
Misfire cylinder #5. Check plug and plug wire for that cylinder. If that doesn't fix it, swap the injector with another cylinder to see if the misfire follows the injector.
the engine is sitting on the cradle already rebuilt so I can't do that. I was under the impression that it was something about the MAF ?( Maybe I should send out the injectors for rebuild)just to be sure. are they the same injector for 3800SC and 3800NA ?
