It's all in the codes, Scott. What do you mean, "again"? How did you diagnose the previous "bad coil"? Be careful about throwing new parts at it; gets $pendy quick! Offhand, it sounds like a bad throttle position sensor. But, the codes tell all. Get a scan tool!

They do inTexas. My '99 had similar symptoms with a dirty MAS. Bought the cleaner, took it out and cleaned it and no more problems. It was throwing oxygen sensor codes (lean burn on left bank) but the previous owner had replaced the sensors twice before I bought it. -- We have met the enemy and he is us-- Pogo Anyolmouse
