well replaced the battery cable and problem is solved... only to create a new one. It is now running like crap, bank 1 trims are way rich and bank 2 are way lean, lt's are at 25 and st's are around 10-15 on top of that. what could that be? i checked my plug wires, exhaust leaks, can't find any intake leaks? thinking something could have gone funky in the pcm with all this electrical problems?

 

did you check all your grounds?

 

The PCM may need an idle re-learn from the battery being dis-connected. There's a procedure for it, but I've found that driving the truck around and beating on it a little bit usually allows the PCM to relearn itself. If that doesn't work I'd start with typical diagnosis (visual inspection, grounds, check spark, fuel, etc.)
