99' Z28 miss and backfire on acceleration What Could I DO?
#1
i have a 1999 Z28 LS1 it misses a little bit at idle but it misses really bad when you accelerate. I have changed pluges, Wires, cleaned MAF, new injectors, 2 new o2 sensors, new fuel pump. Still misses
MODS:Slp air lid, K&N, Headers, no cats
TROUBLE CODE: P0174
If you have any ideas please let me know Thanks
It runs good while it is cold before it gets up to temp
TROUBLE CODE: P0174- System too lean (Bank 2)
What else can I do?? I have changed maf. O2 sensors. Injectors. Plugs. Wires. It currently backfires and misses.
