Yeah it's aftermarket the weird thing is that it was fine driving it the past few months then randomly started doing this. Maybe bad BOV?

So when I get to Normal running temperature is when the symptoms start occurring. After I shift or just rev the engine and don't touch the throttle the idle bounces very low around 3-400 rpm, if it doesnt die, it will catch itself and continue to idle at areound 1,000 rpm and act like nothing...

Alright for sure I'm going to try the gapping and wires thanks for the advice :)

Thanks! I'm loving the boost :) I tried plugs and replaced some vacuum lines, but still missing gonna try wires next.

I wasn't getting signal to one of the wires from afm going to the ecu, ran a wire from afm to ecu and it works! Now that's figured out, I'm getting a miss fire when not boosting any ideas? Super happy to have my car running again!

Drove it around to see if the missing/crappy running a 0 vac would go away but it didn't then blew efi fuse. What would make that blow?

The main relay seems to be working as the car still starts and idles. Could this mean my ecu is toast? Codes 31 and 51 went away? Im very confused... Now it's just the 51 and not the 11 any more...

Could my throttle position sensor cause this code to be thrown? I tested it and if I'm doing it right it might be bad? Getting tired of throwing money at this engine...:3d_frown: Oh and throwing a 51 so I think tps is bad But why 31?!

OHHH ok sweet ya I took my A/C out well thanks that helps A lot now I'm not so worried about that one! I think I just need to go through the wiring really thoroughly...

Lol no I didn't know It was a lex Afm when I got the engine I just bought the stock injectors too... The person that had the engine before me had standalone and so the harness has been chopped a little. I haven't tested the afm yet like I should but none of my friends have GTE... just GE. I...

I thought so just wanted to verify. I'm throwing a 31 and a 51. I have checked the wires at the ecu and at the afm. Was told it was good and being used but now I'm questioning if it is a broken afm?? Is there a common place where wiring breaks or somewhere more specific I should check I'm...

Ya have a GTE block I just didn't know there were two cause i went from GE so I got two today and still runs like poop, but I think I have a lexus afm and only the stock 440cc injectors I'm thinking that/s why my engine is running so bad, might be why its throwing a 31 code?

I think this is right? And possibly why my engine is cutting out?!?

Okay sweet so I just gotta get one more thanks a ton guys!

Well figured out today that I am missing a knock sensor...

Ironically the engine I bought didn't come with the sensors...:3d_frown:

And also I don't know what these plugs go to?

Yeah I have a 3" down pipe on right now I am planning on doing it 3" all the way back but I cant get it running good enough to take it to the shop! Ya I thought so too I have checked over and over and over... and I cant find any leaks I tested the IC and it seemed to hold pressure, the tubing...

Well the resistor and tps didn't help I don't know what to do...

Oh okay sweet that's what I wanted to know hopefully my ecu isn't already damaged, I'm gonna get the resistors tomorrow to see if it fixes my issues
