• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Some help again please!

ok heres the problems im getting.

1. P0102 Mass or Volume air flow circuit low input
2. P0133 o2 sensor circuit slow response (bank 1, sensor 1)
3. P0134 o2 sensor circuit no activity detected (bank 1, sensor 1)
4. P1381 misfire detected, No EBCM/PCM/VCM serial data
5. P0300 random/multiple cylinder misfire

Took the car out to start breaking it all in. No codes all day until i was on my way home. And these codes are the result.

Checked all plugs, wires. plugs were gapped at 55 before car was started last night. pulled them back out and they are all between 60-65 now. How the hell does that work? could that be the cause of the random/multiple misfire. they are 103s. mods are in sig. Coils and ICM are brand new. Could the o2 sensor be shot and causing misfires as well?

Also while driving and it shifts into 4th, and i hold steady throttle just driving, the RPMs arent steady. What could that be? its a fully rebuilt transmission so could it just be it needs fully broken in still?

On my way home i needed to get on the throttle to go up an incline and as i did i heard the noise like a whistle which i thought i have a pcv issue so when i got home i pulled the oil cap to see if it would suck my hand in but no go.

Im not going WOT but when i go to 1/4 throttle i get KR up to 9*. How is this possible when i have a S2 IC on? Should i go back to the 3.4 for now till i have the tune? The 3.0 is on at the moment.

Yes the cam will probably cause a p0300. I would put the 3.4 on for now, you are moving a lot more air and probably running lean as hell.
 
on my aeroforce i was reading LTFT B1 and at bout a 1/4 throttle they were -16 between -22. thats bad isnt it?

I should go ahead and uncheck the 300 code then on HPTuners?
 
well thats better than lean. im gonna check injectors now. vacuum was at 16 in Hg. when unlugging maf it runs ****ty so i know the maf inst the problem. o2 wasnt fried just some wires needed fixed. is there anything i can do with my standard hptuners to kinda fix running rich or wait for someone that knows how to tune to do it?

300 code was deleted. how do i go about checking if my injector table is set for 65 lb injectors?
