2002 Chev. Impala w/3.8 & 24k+ miles. Initially the upper intake exploded. I replaced the upper intake, The MAP sensor, 6 injectors, Fuel pressure regulator. After reassembly started motor and it would hardly run. Had code for cyl 4 misfire, replaced plug wires for cyl.2,4,&6. Started engine& it ran on all 6 cyl, but idle was very unstable. Next code was for O2 sensor, so I replaced it. Still idle rough,replaced the IDLE AIR CONTROL &THROTTLE POSITION SENSOR. Now getting code for multiple cyl. misfire and it will not Idle at all.I need help
