So I'm pretty much done. New hoses, gaskets, spark plugs too idling nicely I adjusted the timing but shes choking and dying when I give any amount of throttle. I'm giving everything attention even jiggling the afm before each start. Only code that's still up is 51 but that makes no sense, I cleaned my throttle body and sensors. The only thing I can think of now is a new fuel filter?

I think code 51 is the tps sensor. Could be the filter, but I don't think so, especially if you are getting the code.

Yeah you're right. I cleaned the connections and it looks to be in amazing condition. It's the sensor right on the tb if I'm correct.

Ya should be.

I got a code 31(afm) too which i thought I cleared but it's still showing up. I don't have engine temp or oil pressure readings either.

Are all these sensors going bad because I dropped in a jdm motor with a usdm ecu?

So much fun!!!

bad AFM...had the same symptoms when mine was unplugged

+1, change it out, Made a huge difference on my supra.

ooh wow.. crazy how things make such a huge difference. Any estimates on what a afm would cost?

What are the chances my tps is bad also judging by the 51 code?

Code 41 is the TPS code

if its idle is also shitty, then it's the AFM. if it just stutters a lot under acceleration, it's most likely the TPS. Could be both or could still just be the AFM but my bet would be for TPS
