ok ordered the upgrade injection system MPI Spider replacement. and it suddenly would hardly crank so i thought what the hell i went ahead and put another new fuel filter went with the 10 micron wix brand last one had roughly 15k miles it was fram brand. well black mud looking stuff came out, i installed it the tahoe crank right up and ran great ugh. but still has rough idle at times not bad, guess now i know i don't have to bust butt to get the new MPI installed. they say that the MPI swap helps the idle issue and really helps fuel mileage plus more power and response. just an update.
here's a pic of the newer style replacement
