i got the 1jz running and it's running rough, my tach doesn't work but it's idleing pretty high i would guess around 1200-1500 rpm +/- and it's also missing and if i try to give it gas it bogs out and dies, if i try to creep into the RPMs the Rpms do rise but won't go higher than 2500-3k rpms(it begins to cut out and won't go higher, if i try to force it above that it bogs out and wants to die), soooo to me it seems like it's in limp mode :1zhelp:

checked for codes... i'm getting code 12... TSRM says cam sensors, crank sensors and ECU. i'll double check the ECU for leaking caps but last i checked they were fine. so would i would like to do is test the resistance in the cam and crank sensors and see if they're within spec before i go buy new sensors and find out that's not the problem.

any help or advice will be appreciated

P.S. i did try to look into the 2JZ TSRM to seem if i can find info on the sensors and i didn't see any unless i missed it.
