Plugs/wires just changed. Dealer checked everything out to be OK. I have SES and it's cylinder 6 misfire. I check it and it's all good. It still misfires under LOAD only. Rev it up and it won't misfire. Throw it in gear and get it to pull it misfires BADLY. Like 75 misfires/second on the one cylinder.

Make sure that the plug wires are on good, especially the middle ones. They're difficult to get to, and it's easy to pull the boot off of the plug when you're putting the heat shield on (I know, I've been through it).
Next thing to check would be the coils. Quick and easy check (this requires two people). Pull both of the wires off of each coil (one coil at a time), and have the other person turn the motor over a couple of times. There should be an arc between the two posts. If there's not, then the coils are most likely bad.

Hey, I had the same problem, only under pull, I had misfires, I checked everything, plug wires, plugs and you know how hard it is to change all them> After all this I borrowed a Snap-On scan tool, it turns out that the center coil pack. It had enough juice to fire withoud a load, but under a pull it failed causing number 5 to misfire like 80 times. It costed me $100 to take it to a mechanic to fix. If I would have known that there were only two bolts to remove, I would have saved $50 of that.My car looks great and runs good. <br />Please Look at my car, it may be one of a kind!!!

If it ran great and now doesn't, you might be burning a plug wire somewhere -- the insulation burned through over the course of a few days. Did you re-use the dividers / loom stuff / etc? Be sure and get them away from the manifolds, they're a main source of burning.

couldn't tell you. I tried fixing the car myself and then I handed over to my parents to take back home and fix. I'm too busy down here to muck with the car so I have no idea. I'll try and find out more details.
According to my Dad the car was running OK after the first repair but the motor wasn't "smooth" so he had the injectors checked out and the car runs better than new according to him. I sure hope so. I'll be picking it up tomorrow.
