Possible Fuel Delivery Problem...
- Thread starter nmskull66
- Start date
WOAH fella start with the basics has PM been performed/up-to-date (ie tune, fuel filter, etc)
some people describe bogging and actually felt misfires
are you setting p0300-0306? whats your gap? if there is any chance when you installed the plugs that you may have experinced binding while tightening/off angle/ dropped plugs/ moron or drunk buddies helping you might want to drop the dime on a new set of coppers to eliminate a broken porcelin/bad plug as the culprit.
if its actually a fuel bog it could be a bad tune/tables, injector issues, crushed or kinked fuel lines, clogged fuel filter, incorrect/failed FPR or a weak fuel pump (a good shape GT pump will not have any issues with what is essentially a mild motor (an L367 with headers and 3.6 correct?)
unless it was weak to begin with -if you have done the PM and when you pulled the filter out you got dark fuelout of the upstream side, that pum may have been working really hard for too long and the vanes no longer seal properly, its time is....well
whats happening, rpm, mph, bottom of each gear, didja just fill it with bad gas right after finishing it? throttle position? do any work other than the topswap? just by yourself or were there 6 dead hookers in the trunk? details mang!
cliff: rent a fuel pressure gauge from a parts store and go for a drive

is it truely a bog? bogs can be fuel and spark related and act differently

FAIL... Get that tuned quick, you might have the same BS that Steve had in his regal
7*+ of KR on a "Dyno" tune, yeah..... From a newb mistake that a professional tuner should have caught, shit, or they could have just felt it give up at 5800 rpm on the dyno, I'm sure the graph had a decent fall off
