LT5 Misfiring at All Speeds - ZR-1 Net Registry Forums

Big D · 07-17-2015

hi everyone, couldn't figure out the miss so i put in new coil packs, wires and plugs. Still missing at low idle and while idling down the road. Also, get a bad hesitation off idle. Still screams to 7 grand though. So tonight, after putting the new plugs in, i have isolated the miss to number 6. Pulled the wires on all other plugs and the idle changes noticeably except for number 6. Pulled the #6 plug and it is bone dry, never saw any fuel in the short time it was running. The injector ohms out correct. Fuel pressure is good also, holds after shutdown. Could the new primary injector at # 6 be questionable?
