Sorry for the late post back, Problem solved.. I removed the whole harness to find this issue.. Seems that the +b wire from the ECU passing through the firewall was cracking due to age.. cut the old wire out and re-ran a new line.. runs perfect... Although I have a new problem lol.. that is for...

The tranny makes a "whine" sound in park, neutral, or drive.. However the sound gets quite after the car warms up.. Think its a fluid starved tranny? I will drop the pan. and change filter / fluid. Also I was gonna adjust the kickdown last night after reading this, the kickdown cable it...

New plugs in, gapped to specs in TSRM, NGK coppers. Throttle response feels a lot more responsive. Old plugs looked like I was running really fat. Found a issue on why I am probably feeling a breakup, my #1 plug wire is worn down to the thread insulation.. I am sure it is arcing over and...

I have checked for codes.. No codes and no CEL.. just steady blinking. I think I am gonna pick up some Autolite coppers tommorow and gap them as per TSRM and see if that will help. -Matt.

Well, Kind of both :aigo: The car seems to bog at 3000 RPM and drop down to about 2500 RPM and will make like a machine gun breaking up sound as I go higher.. Unless I go WOT and the auto tranny kicks down.. I know its strange.. :1zhelp: -Matt.

Also maybe the plugs are causing the break up? They are about 1yr 2months old. -Matt.

The KS wires at the ECU plugs should be transparent.. You may be looking at the wrong wire set.. There are 2 brown wires running from the AFM -> TPS -> Water temp sensor -> HAC sensor to the ECU. -Matt.

Ok so here is what I did today.. Did the KS re-wire, put a new KS in, re-calibrated my TPS, set timing to 10 BTDC... Still have strange bogging issue.. it bogs down right at 3k RPM, doesnt really want to go above it unless I go WOT and let the auto kickdown.. Perhaps its a AFM issue?? I am...

I do not have a wideband yet, I am shopping for one as we speak. have only put the car in to boost 2 times, I am gonna stay out of it until the wideband arrives. I have no codes being thrown. I have wired both signal wires in to 1 sensor. It is not a knock sensor problem I dont think, I can...

Hello everyone, I just finished my "build" of a NA-T setup, let me 1st go over everything that is installed and then the problem. Car: 88 Turbo supra Engine: JDM 7mge (Did not have the money at the time for a new 7mgte) Ajusa HG, ARP Headstuds, 304SS 2.5" IC pipes, HKS SSQV, HKS Super...

Not totally sure about the surface finish.. However I have been using the Ajusa for almost 2yrs.. VERY awesome gasket.. I would def. buy one again. -Matt.

I am sick of this old wire harness!! I have had nothing but troubles with it the whole time I have had the car. Car still does not run... -Matt.

I have been using a 14mm 12pt deep well made by craftsman for doing the ARP headstuds.. The only thing I can think of that we might have different, I am using the NA cams.. I dont remember having any sort of cam clearance issues.. -Matt.

Stock boost levels on the Felpro will be fine.. I actually prefer the OEM gasket if staying low boost.. I understand the money spent.. We all shell out good cash to make the head gasket problem as reliable as you can make it.. I have been through 2 Oem toyota gaskets (not counting the...

Just happened last week, Friday. Was at a stop light waiting to turn.. everything was running fine.. went to give it gas and it blew the fuse.. I am running an auto tranny. Its strange, I can keep it in park or neutral and rev it up to redline just fine, but put it in drive and try and go...

So you thinking its a possibility that the EFI main relay could be bad? I have never tryed touching it when my car ran fine.. but today that sucker was to hot to even pull out of the relay socket. -Matt.

Just take it slow and do things right and you will be just fine.. If you have problems or questions as you go, just do some searches on here. You can learn a lot from this forum. On a Felpro HG, dont plan to push to to much boost.. Also just a note on assembly with ARP headstuds, make...

Hello everyone, Before anyone gets there undies in a bunch.. I have used the Search function very extensivly for a week now. Now its time to ask some Q's. Car will hold a idle for a hour+ no problems. I put the sucker in drive and give it gas.. sometimes I can drive for maybe a few feet...

I realize this is a old post. I just noticed a situation that has not been covered. Could help someone down the road.. Digital Multimeter's tend to have a good continuity testing circuit.. However! Most meters will only give you a short indication when the circuit resistance is less than...

Thanks! I am sure I will need it.. I LOVE my supra.. seems it hates me at times though.
