Well... she runs smoother and the hesitation seems to be gone after swapping out the coil pack. I just filled up, so I'll be able to see if my mileage went back up from the ~21-23mpg it was down to.
Oldandslow, did you install a new replacement coil pack?

Re: Misfire and stuttering under load.
Definitely keep us updated, I have the exact same issue as y'all do, if I keep it under 10% throttle or so it'll rev to redline however. I took the coilpacks out and redid the wiring (GD coils) to them, it seemed to help some. The coils looked ok but maybe there was hairline cracks.beatersubi wrote:Well... she runs smoother and the hesitation seems to be gone after swapping out the coil pack.

Re: Misfire and stuttering under load.
Filled up today to find that the car got 25.4MPG. Not the best that she's ever done, but a definite improvement. And the with the stuttering/hesitation gone when she gets into positive manifold pressure, I'm less hesitant to take her there.

I read through the whole thread and realized that you never smoke tested the car. I had almost the same exact issues which is on here due to the intake manifold being cracked. Try smoking the car to see if there is any leaks.
Thought I would throw that in since I experienced a lot of issue like you and would of never thought it was my manifold (I even changed the manifold gaskets and didn't see the crack )

Re: Misfire and stuttering under load.
That's a good suggestion. But I think replacing the coilpack has resolved my issue. This might help the OP, though. Oldandslow, did you ever check for leaks under positive manifold pressure?subiedoutlegacy wrote:beatersubi wrote:Filled up today to find that the car got 25.4MPG.

Re: Misfire and stuttering under load.
Well I finally figured it out. Took it to a local speed shop and the dude there was super knowledgeable. Had a whole table of spare parts ready for when I got there. He threw a used maf on and voila! Car runs great now! Check engine light has gone off as well and stays off. It's still slow haha but at least the drive-ability is there. Now the only thing wrong is my speedo reads 12 mph too fast. At least that's not a huge issue.
