The multimeter is not mine. We have a shop, regular mechanic shop, no high performance stuff, it belongs to a mechanic. Should I get a different multimeter then? Lastly, I know I should be testing the AFM at the ECU terminals to know the voltages it sends. Were you thinking I OHM'ed the AFM...

Ok, so I should leave the TPS now as it is good? Yes, I mixed up the darn injectors even after I OHM'ed them. Had both of them laid out on rags after cleaned and picked up the wrong set. That could be a problem. I know I have to check Vf right? Ok, I installed the 195 thermostat, so that is...

You will not have a CPS plug, only one knock sensor plug, I believe a different TPS plug and no coil pack plug. Just look around for a 7MGTE harness for sale. Check the classifieds.

Today I finally got the chance to test the TPS and other things. I Used A New Snap-On Multimeter With Aligator Clips And A TPS Pigtail I Got From A Old Horrible Harness I Had Laying Around. Here is what I found. Testing The TPS According To TSRM Incase It Makes A Difference, Since "E2" Is...

He gives hints, makes you wonder and then finally give the full answer. It is the reason why a lot of people get an attitude with him, but I figured that it is his way of helping:dunno:. It is the reason I am not acting like a douchebag like most people would.

I checked today but could not do much, it started to rain really hard. I had a -6 AN oil feed line going to my turbo. I was supposed to use a -4 AN, so I had to change it out. Car was smoking and the turbo is brand new from Aaron at DriftMotion. That is good now. Then I see the housing for...

Ok, I am going to try it. it rained all day today here in New York, so I did not get a chance to do anything. Tomorrow I will, better weather and no class on Friday. Ok, so what I am understanding is 1) I should test the AFM at the terminals of the ECU and 2) It should idle fine without the...

Yes, and the IAT is in the AFM so it needs to be changed.

Well Jetjock, if I have a code 31 on one AFM and a code 24 on another one. Your telling me that they both can be good? Going to swap out my last one today. My wires should be fine since it is a new Toyota harness I got, but I am still going to check the AFM plug's terminals with my voltmeter...

The TSRM says to disconnect it. How am I supposed to test it on the car? I read that testing it on the car wil test the ECU's resisitors. It was on the here. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?Section=FI&P=96 Do I still use the TSRM's specs then?

What am I doing wrong? Codes, AFM?

I know code 31 is the AFM, that is why I am changing it. What are the chanced that my wiring harness from Toyota is defective....brand new. I am the first owner for it. :) ECU, I have not seen a lot of them go bad but I have a spare to try.

No, I took a summer class and I had a lot of homeowork to do. I will try and swap them out tomorrow. I have three. One gave a Code 31, the other I cleaned with brake cleaner, and the other has a inch hole on the top covered with electrical tape. 2/3 are bad, I am going to try the last one...

I am not sure it is a vaccum nightmare. I am getting 21 vaccum. There are only five main ports for vaccum, front of intake behind the alternator, rear of intake, two ports on the throttle body and brake booster. I am not using power steering, so there are no lines that go to it. It is capped...

Did you ever install the COP again? That COP and Jetjock's ignition grounding write up would be a nice combination.

Really, called Aaron since I get everything for my Supra from him, and he said that the injectors can be a problem. I will swap out the AFM though.

I decided to OHM everything and looks like the AFM is bad and my injectors are 13.4-13.5 which are in spec for GE. WTF? I got these injectors that was on a turbo engine that I took apart. GE injectors on my GTE, maybe that is why it refuses to idle but revs fine? Summer class tomorrow, so I...

1)Yes. 2)Yes, Coil Pack Firing Order Was Used. 3)Going To Do That Now. 4)Not Sure, Going To OHM And See.
