Did my plugs today, it went extremely smooth and problem less problemless...... Until I went to drive it, sputters like its mix firing, shakes the whole truck sometimes, no cell bit my edge is pulling p1071, bank 1 too lean....any thoughtsthoughts??, thanks.

 

I would go back over your work, check for stuff unplugged, and maybe retorque the plugs.

 

Double and triple checked. I've checked vacume, its frustrating because it really is undriveable and its not throwing any codes now that I've hooked the battery back up. It feels like a cylinder or 2/is dead.

 

That kind of thing will drive you nuts. I'd double check your coils are plugged in good. I noticed that the wire connectors for my COP's don't always want to click when I fasten them together unless I fiddle with them. If the truck was running well before, it's got to be something simple. Seems unlikely, but you could have purchased a faulty plug. Wish I had a better answer for you. Good luck and keep us posted.

 

Thank you sir, yea today I literally took all the plugs back out, inspected them, inspected all the cop, insulators, springs, wiring etc. Then I drove it about 6 miles trying to get a stupid code telling me what's wrong haha. No luck. Its got to be something simple. I will keep posted.

 

SP515 plugs?

 

Yes. 12 bucks a peice haha

 

Hmm, try the battery relearn process:

Did it also. I just remembered I unplugged the vct solenoid to check for corrosion , but dont remember if I plugged it back in. I'll anxious to get to work and check it out tomorrow. It then again, I would think that for sure would throw at last a soft code, and dont think it would have anything to do with the code I originally got...

 

Hmm... Maybe the cop boots, and did you use dielectric grease in them? Just throwing ideas out there, hope you get it figured out
