ogden,
Utah
i just put a new motor in with 272 cams, springs, retainers, ss valves, 3 angle valve job, 2g pistons on 1g rods, arps throughout, cometic head gasket, so new anything on the motor
and 850's, stg 3 dsm chip set at 850's, afpr, full intake and frontmount, full exhaust, cop setup, gm 3 inch w/ translator.
the timing marks are on
timing is set at +5*
so it misses at idle and my wideband reads at 17.5 and some times more and some times it runs fine and go's to 13 or so.
and it misses and jerks at a steady cruise as well and reads at like 15
but when i give it gas or WOT its fine and its at 11.1 and hauls a$$ ????
so i swapped to stock injectors, mafs and ecu and still does it
so i ordered some new plugs the 7es plugs
unpluged one coil on plug at a time and runs worse when i do.
used a noid light to see if i was getting pulse from the injector clips and their fine
i dont know what to do now
can someone please help!!!! thanks!!!
