1jz problem Please Help!!!
Well ive had my swap done and running good for a while now...Yesterday i decided that i needed to extend the ecu wires finally.. THe car starts up but it dies a few minutes later...Also i try to give it gas in the park position and and it bogs and wont make it past 2k rpms....Did i screw up on the extension of the wiring or could it be something else?

Yeah THe Rpm signal is still good but the idle is extremely low , LIke 400rpm and after i leave it on for a while the car eventually dies...this is in the park position!! SO use shielded USB all the way to the Knock sensor? I only used the USB for that little portion which i extended? Could that be the problem?

re:
sounds like problem i am having
my stock ecu is not as extreme, i can start to drive it, it bogs real bad getting ready to stall, then fixes w/e and is good to drive
the power fc bogs at the same spot, but doesn't fix itself and continues to bog...will not rev past 2700rpms
no dying at idle though
i am currently redoing the fuel. then i plan to check the afrs, and then the timing.
change ur filter, since it's only $10(if you didn't do it during the swap)

What do you mean by "extend the ecu wires"?
I had a similar sounding problem when my MAP sensor was not plugged in properly. Have you double-checked all your electrical connections?

By extending the ecu wires meaning. I cut every ecu wire one by one and extended it and soldered it. I dont know what could be wrong here.? I look into the Map sensor deal...Any other ideas?

im with you ^^^^ this happened to me on a sr20 swap i did. if it happend after fooling with the wores then thats most likely where your problem is. a grounded/crossed/unpluged map sensor wire will do that. get a volt meter and wire diagram and make sure all the volts are right in the wires, also make sure your grounds are good.
