Just an FYI, if you replace your harmonic balancer with an aftermarket one like this one http://www.titanmotorsports.com/timoda2jcrpu.html, you will need a new serp belt that is two inches longer. I got a 77 inch one and it works perfectly with the AC and PS.

I did my 1JZ swap and used an MSD tach adapter from DM(http://store.driftmotion.com/static/i-msd8920.php). My tach works fine, and my speedometer works fine too. I did disable the ABS since I forgot swap out the speed sensor on the trans, and I got tired of looking at the ABS light.

I got an AEM ECU in it now, and it runs like a champ. If you have not had your capacitors replaced yet, I would go that route first. Driftmotion will do them pretty cheap if you don't feel comfortable soldering them in yourself

I sent it to you. Thanks.

Thanks.

I have an AEM series 2 ECU, stock injectors, stock twins, AFPR and 3" exhaust. It runs good, but constantly oscillates at idle between 800-1400 RPMs. I am using an AEM wideband as the O2 source also. Reading other posts, I suspect it might be an IACV problem, but can I just remove it and...

OK, I checked my crank sensor and the cam sensors using my meter and oscilloscope, with the troubleshooting steps from the 2JZ FSM engine troubleshooting section. All check out OK. Anything else I can check out before I drop the money to replace the ECU? I am looking at getting the AEM ECU from...

any idea how I can check them to see?

I got the new coil packs in, it is doing the same thing still. There are no fault codes. When I first start it, I can take it up past 2000, but after a little bit (20-30 seconds), it keeps shutting off at 2000. My wideband and AVC-R both show the injectors shut off, so it is like it is...

OK, so I have not replaced my coil packs yet, but I did put some heat shrink around the two that had cracks. It made no difference. If it sits for a day, I can start it up and it will rev normally for a few minutes, then it is back to the 2000 cap. Still no codes. I know I need to replace the...

#3 coil pack has a little crack underneath the rubber boot. after I pulled them all and reinstalled them, it went to 7500 once. Since then, it has been limited to 2000. If I go full throttle, or creep up on 2000, it shuts off at the same point. I'll see if I can find a coil pack locally, if...

Shouldn't that cause a code to show? Is there a way to check short of replacement?

All tight... thanks

I am in Florida, and it rains just about every afternoon this time of year. I drained my tank when I changed the fuel pump, so the gas is pretty fresh. It does it in the morning before it rains too.

Melbourne. I will pull the coil packs.

Melbourne.

Oh, and I replaced the caps in the ECU when I did the swap.

I did my 1JZ swap about a year and a half ago and everything has been going great until last week. It won't go above 2000 RPM. When it tries, it is like it hits fuel cut, as soon as it gets below 2000, everything is fine. I was getting codes for O2 and TPS, I replaced both, both faults are...

good find!

I did my 1JZ swap into my 90 for just under $4000, and it was money very well spent. Before you drop the new engine in, do all of the preventative maintenance while it is easy to get to. Water pump, timing belt, etc. Do some research and be ready to wait for those oddball parts to come in the...
