My buddies 01 gp is misfiring on every cylinder, but is only throwing a code for cyl 1 misfire it also stops missing as soon as you apply any throttle. Also here is this hope it helps. plugs are also factory gapped, and has a new reman injector on cyl 1... I checked all the valves when i put headgaskits on it they seemed to be fine, no signs of burning and didn't leak at all. Thanks! hope y'all can ease our headache.

Have you triple checked the firing order and ensured the coils if labeled are in the proper places?
02-26-2013
Yup firing order is good. I've checked it probably 20 times, and even put a new coil temporarily in place of the 1&4 coil to see if that was the issue. Even though 4 isn't missing as much as 1.
Thanks for the reply.

~180psi. =/- about 5% is acceptable.
You know.. I have seen something screwy like this in the past. Try a crank learn. aka case learn.
