2002 Chevy avalanche
MY TRUCK STUTTER WHEN I START IT UP AND WHEN I
GET UP TO BOUT 30 mph or more it’s smooth out but
engine lights start blinking I change the coil pack and fuel
injector still didn’t fix the problem I need help ASAP
the light will only flash when there's a misfire,keep at it.
Yea but where the misfire I took it to a shop and it said that it was one fuel injector i change that still same thing
I change the plugs and wires still same thing
pull the plugs again and make sure you didn't accidentally crack one,not the first time that happened to anyone.
No all of em seems fine
well then its scanner time, to see which cylinder is giving you the issue.
