This is my first post here but have been following and searching this forum for years with anything I needed help on and it has been great.
I finished rebuilding my engine and got it in my car it revs freely up to ~3000 rpms in park but has no power while driving.
What i have:
2004 grand am
bored 20 0ver
engine balanced
wot tech street/strip cam
stage 1 ported heads with 3500 valves
comp 26986 springs
arp head studs and rod bolts
pacesetter headers
diy ported upper and lower intake (not even gasket matched)
Still has stock air box and stock exhaust with gutted cat i thought it was clogged.
Getting a check engine light for p0336 and tried to get a local guy with tech 2 to do a crank sensor relearn and he say he couldn't because the tech 2 show 2 other codes one for no oil pressure I added an autometer gauge and the other for low voltage for 02 sensor.
I currently have not had the pcm tuned yet is there anything other than a tune that will help at this point? I feel like it is running lean.
After searching i realize the low voltage to oxygen sensor is probably because i attempted to cut and extend the pre-cat sensor. Does any have a better suggestion on extending the wiring to reach the bung on the headers?
I have a new rear o2 sensor can I use that for a front O2 sensor I believe they have the same plug and are both 4 wire?
