Truck seemed a little down on power and gas mileage went from 12 to 9 while towing my boat. Put in new plugs (NGK TR55IX gapped @ .039) and six new coil packs. I drove around the block and now when I'm barely on the gas she's sputtering. No SES light on, should I wait to see if it comes on? Could it be from the fuel trim not being completed properly? (I forgot to do it). Could I have a bad coil, they all tested good before installation. Any ideas? Truck is all stock except for K&N drop in and exhaust.

ANYONE want an lightning???? This love hate relationship is going to be the death of me!!!!!!!

Thanks

sounds like either you have a bad coil, OR did like I did and forgot to plug one in fully

 

I think I found it! Brand new coil on the #2 was no good. Started swapping out and luckily got it on the second one. We'll see how it goes from here.
