Got it fixed, it turned out to be low power supply. Looks like I'll be needing a better setup. Glad to have it running good and thanks for the help.

Radial: The injectors are wired as 1&4, 3&5, and 2&6 together. I think the fuel filter still should be improved for the current setup. Good call on the bypass. Miekedmr: The AEM does work with the stock ignitor and coils, I had another ignitor and swapped it out with no difference. Hvyman: As...

Racer, yeah the compression is great thankfully. Radial, I hadn't thought about the injectors clogging. When the tune was done it was running perfect, the misfire started happening very intermittently at the end of the tune when he was just doing some minor things. We considered it done so I...

The boots have all been shrink wrapped twice over.

Spark plus are from 1-6 from bottom to top. 1, 3, and 5 are clean. 2, 4, and 6 are fouled.

I have a pestering misfire that has progressed, I am puzzled and am in need. I own an 89 NA to 1jz convert. It has an AEM v2, Bosch 750cc injectors, upgraded rail and pump. I have an extended wire harness that was checked and is good. Fuel pressure is good, coils are well insulated, not sure...

I have an 89' Supra with a 1jz swap with the capacitors replaced about a year ago. Click the pictures for larger shots. I drove the car home one time and tried to start it up the next week with it not firing on cylinders 3 & 4. Plugs are good, coil packs are good, and the resistor are all good...

Awesome, I couldn't get ahold of a tester so I wired straight to my tach. No movement at all. I'm going to go ahead and get the igniter. That tool does sounds handy though too, I may have to come up with an excuse. Thanks

Since I have done the swap not long ago, the tach had never worked. It was an NA originally, but I have put in a turbo tach and have a converter. None of that made the tach work. So now I'm doing what I should have started with, the wiring. Well I have no signal when I jump the tach straight to...

Thanks for pinching in on the info, guess I'll start my look for a tach/cluster. Would've never guessed the airbag would have made a difference. I haven't seen a turbo supra in a car yard for a good while.

I haven't, I have only jumped it before I put on the msd converter with no change. Figured the convertor would allow me not to have to mess with that anymore.

I've searched and tried several things, just can't get it to work. I have the NA tach in and the MSD 9210 converter with it wired to RPM1 on the ecu and then the output to my black tach wire to the dash. I have very little movement on the tach (under 1k when I give it good throttle). Maybe I...

I've got an 89 that runs and drives great, but I can't seem to figure out how to get these gauges working. My speedometer doesn't work but its the na stock one so I will figure it out later. The oil pressure gauge doesn't with a new 7m sender and the illumination doesn't come one, dimmer doesn't...

I've got a turbo guy in town. My brother actually has some IHI's but he would need a custom made adapter. I'll let him make the decision.

Thats what I thought, just wanted some more opinions before I wasted my time pulling them off again.

At the alternator fusible link right.

Its oil, a little dirty but oil for sure.

Its smoking good, really when it warms up. Its not coming into the manifold, thats why I was assuming the turbos, didn't know what kind of seal would go inside them?

On my brothers 1jz, I am not sure where the large (12ga?) wire goes directly from the alternator side post. I imagine eventually to or near the battery to charge? Just wanting to make sure I am wiring it to the right spot, not his radio, radiator, or kidney.

Alright after I got my brothers supra going and we left the cat and back portion of the exhaust off. I started it up and have been running it, but it appears to be slowly dripping oil out of the exhaust. Is this coming from bad seals from the turbos? This car had been sitting awhile before I was...
