Last week on the way home from work a few blocks from home, I nailed my beast (99 L) and it pulled good (kicked down at 45-50?). When it hit the 2-3 shift if fell on its face, sputtered with a funny sound and had no power (similar to hitting the fuels cut off and loss of boost together). Kinda feels like she was wet in distribution department (can't be) so I figure a bad plug. I parked it took the old POS for a while.
Last night I take her for a spin and the Check Engine Light comes on. It is running allot worse than I thought. No power on the bottom or midrange, idles with a faint mis, chugs at times and has a strange sound (fluttering, chuggy, whine?) to it under load. No oil in water, no water in oil, that I can tell. I have the dreaded IC leak (waiting on the real deal to come), have added about a quart or so 3 or 4 times for about 2500 - 3000 miles with 13.400 something on the dial. No chip, just a PRO-M 80 and filter. This was a sudden problem like a snap or the finger.

HELP! and suggestions before I take her in. Last time I had a problem the jughead tech. replaced my MAF and re-flashed my ECM (with me telling him what was wrong) trying to trouble shoot for the fuel pump problem.

When those stock POS plat plugs fly apart, they do it at high boost. did it immediatly run rough after the 2-3? sounds like your running on 7
