BLACKOUT22

I had a CEL light come on. It had 4 codes. 3 of them were a misfire on cylinders 1,7,8. So I replaced all coil packs. Now my truck has no power when you get on the gas. So I'm assuming that has to do with the "bank 2 lean" code. Any ideas on what this could be? Any help is much appreciated!!

Have you cleared the codes and trigger them again?

Also disconnect your battery and hit your brakes. Leave it disconnected for thirty min. Reconnect, fire it up, and let the pcm relearn.

Why did you replace the coil packs? A bad coil would be indicated by a Rich condition not a lean. You either have a massive air leak or faulty injectors, low fuel pressure, bad MAF or something in that aspect.

The lean code set the misfire codes, not the other way around.

I replaced the coil packs due to it reading a misfire on cylinders 1,7, and 8. They told me that there was a bank 2 lean code as well.

so all 3 COP's went bad at the same... doubt it..

I replaced number 7 maybe 2 weeks before it threw codes for 1 and 8. That's when they also told me about the bank 2 lean. I have 130,000 miles 07 fx4. All original coil packs. I've replaced 4 out of the 8 so far
