I bought my truck with 130K last week. This weekend I put a timing set, cap, rotor, plugs and wires. I also adjusted the valves just a tiny turn past spec. When I took the plugs out they were at a worn out .056 gap. I gaped the new plugs at .034, but it seems the next time I started the truck right after I did the plugs, which was the last thing I did, the truck has a slight miss at idle. Fine power through out, but just that slight occasional miss at idle. PLEASE HELP!!

 

Your sure its a miss and not an exhaust leak? Put the vehicle underload in par and see if it still makes it, then drive a bit and check. Look for exhaust leaks too..

I would duble check you have the correct firing order and installed everything properly as well.

 

What specs did you adj your valves at? What kind of plugs did you get?

 

never mind. I didnt seat a plug all the way. Lucky I was able to seat it. hope I dont have to heli coil a cylinder next time
