Need Help ASAP...CAR Jerking/bucking badly

[kentpsmith]

NightRider, thanks for closing the loop on this.... Like you I have about 240k on my '97 Q. Mine stumbling seems to get worse with heat. When the car is cold I hardly notice a problem. And with winter here, it doesn't seem as bad as a few months back. Now I have to drive the car for 1/2 hour or so to notice it. I suspect the coils. Just curious if your MAF problem changed with heat.
