Well, I just built an Engine for a friend of mine about 2 weeks ago. He gave me a call sunday night saything that he has alot of steam coming from under the Hood, I Asked where was it coming from and he said its coming from the back part of the motor. I asked have you driven the car anymore...

Maybe Im doing something wrong.... Im going back outside now and rechecking it again. I dont think I had the E and t Jumped when I did it yesterday or maybe I did. Jump the T and E connector so that the CEL is flashing, Put the Multimeter on the VF and E1 (or Neg Battery Terminal), Rev...

Ok all, I went outside this morning, Started the car up, Ran until completey warm, Jumped the T and E connector and with the muiltimeter connected it to the VF and E1 which was showing 5.00, Pulled the small vavuum hose off the Intake and and shot some Carb cleaner inside, The engine...

I will have to try that in the morning. I will give you an Update if the Signal changes. If it doesnt then what should I check or do next? if it does then what?

Simpson Model 467 True RMS Digital Muiltimeter with Dialog Display. I used both the 2V and 20v Switch

Yes sir but let me go and make sure one more time. Checked again, bouncing between 0.03 and 0.04 at 2500rpm T and E1 jumped

Jet, Try anything at this Point. I have another harness coming if the guy will ever ship the dam thing out. As of today, nothing yet.

hehehe.... Its all good, VF and E1 is 0.04-0.05 and bouncing between them, Engine completely warm

Only codes now is the Code 43 (Starter Signal) which we talked about that already. I Checked VF and what Im getting is that At Idle with fans on Im getting 0.17 with A/F at 16.8, Now if I sit there and with my hand hit the throttle really Quick the VF Signal will go from 0.17 to 0.00 and...

Will do, Changed it back to 40 and it didnt make any Difference really, Still Idle at 725rpms showing a A/F ratio of 17.1 or so and Im getting a faint pop sound from the Exhaust which Im assuming its the a/f

Adjusted the AFPR from the 40 psi to 35 psi as we talked about. Low tune on the MAFT Pro is 00 across the board so Im not pulling or Increasing as I see.

So I took a reading without the jump connector. VF and T voltage is 4.93 consistant. I still have the car Idling so as soon as the fans Kick in I will check the voltage again to make sure that the engine is completely warm. VF to E1 right now is a Consist 0.03v and A/F on wideband is...

Yeah, I will get you those readings tomorrow, After Adjusting that screw as we talked about It started up pretty good without the Stumble like usual. Doing the PVC hose as we Speak so that is correct. I need to find another EGR Valve assembly as I have the back Plate but I cant find the Assembly...

jdub, Im correcting all of those things that we talked about and Im making sure the other things arent clogged. I also as you mentioned think its a Harness Issue but once I get all the little things corrected, We will see where it ends up at. I need to email the Person that we talked about...

Ok... So I go and Install a 190 stat, It takes longer for the fans to Kick on which is good I suppose but one they come on, they dont want to go back off. I use a Muiltimeter on the T1/E1 and its a Solid 4.99 with engine at 2500rpms. A/F is 17.4 at Idle but its not Sputtering like it did before...

Yep, 18 1/2 Years here. Looking forward to retirement which means more time to Tinker with the Supras. Not for sure where in going to retire as Im originally from North Carolina but If I like it up there enough I might just retire there. I dont mind the cold but I hate the Heat. Been here for 4...

I will be moving to Fort Lewis Washington in Late march, Early April and the normal temps up there are alot different than here thats for sure. Going down to the Store and getting a Thermostat now. Hopefully this solves my Problems and I can feel comfortable again. Ive been Afraid to drive...

Ok, great....... So would you recommend me getting a 200on/185off sending unit or just stick with this one. I mean if its not going to hurt anything then I will go down to the parts store right now and Pick up a thermostat.

Well, If I check the OX signal at teh check connector its setting a 0.07 and doesnt move but If I go to the O2 setting on the MAFT Pro, Its reading anywhre between 2 and 3v, mostly around 2.70 or so after warmup. I heard and since Im uping a 185on/170off sending unit that I counldnt put a 190...

Yes, My O2 sensors are working, Ive replaced it with a new one and I have also checked the reading on my MAFT Pro for 02. Im running a Aftermarket 3 core radiator with Ford Contour electric fans and my Temps just go over a 1/4 gauge most of the time unless Im sitting Idle for a long Period...
