Thread: Handful of problems after putting motor in

i really dont think its a vacuum leak, of course i havent pressure tested the system. Right now im rechecking the wiring on my maf, is it normal that a white wire and orange wire are surrounded by like empty wire in a gray bigger tubing on the sr20 harness side?

Yeah, that's normal. The outside wire is the ground, and those two inside wires are the 12VDC power and 1-5VDC signal.

I would definitely pressure test the system and check for boost/vacuum leaks. Anytime you touch something related to either, it's good to check to be sure you didn't introduce any leaks.

I pulled the plugs and it looks like im running lean/hot. I dont get it was never doing this before.

you sure

I thought the outside wire is 12v postive

Well all the injectors are deff working, i pulled the rail and first did it by turning the key to see if i had a leaker and i didnt, then i turned the key to see if all of them fire and they do.
Im really at a loss here, i wired my rpm signal for my tach into the ignitor? thats next to the coil, same green with yellow stripe and i still get my rpms
it just idles horribly and hesitates and seems to be running lean/hot
but it still started spinning the tires in 3rd gear that was nice

fuel pressure at idle is around 45

things im going to try tomorrow are maybe a new fuel filter? i was thinking an old clogged one might make it run lean but i doubt it. and a o2 sensor, when i unplugged the o2 sensor it seem to idle a lil better which i thought was odd but still had hesitation
my spark plugs are still gapped a .025 like they were before this all happened
what do you peoples think?

My bad At least you knew where to look. I always seem to get them confused.

haha i search like a mofo if i dont know an answer, except for whats goin on with my car right now lol
