1jz drift....

i dunno thats odd

the fuel filter is inbetween the gastank and the diff. a real tight spot but not bad.

i dont see how the fuel filter would just clog up like that unless from sloshing around the gas it just shook something loose and then got caught in there.

i dunno

where you at the drift event in phoenix?

no i was in the drift event in utah.

but um i just finished switching out the filter.... same problem.... now i think its my turbos.... the car is running really rich also. i did check the spark plugs and coil packs, they all seem to work fine, the plugs were just covered in carbon (black)... maybe my injectors.??
so i found out when i rev the engine up to 11boost in neutral on the boost gauge the car starts sounding like its out of gas, feels like a rev limter but i dont have one. what are the symptoms of the turbos going out? or at least one?

map sensor, lost its vacume source?

How are you intercooler piping looking?

I'm going to go with the ECU has a problem. The injector drivers in the 1JZ ECU's are faulty and will cause the injectors to lock open. Since the injectors are batch fire on these like the 7M's, it actually locks two injectors open on paired cylinders. This can been seen with a mulimeter by testing the current at the injector clips. Two of them should be seeing a constant 12v signal without pulsing.

check vacums first. anyone could have popped from you being on the throttle. Have you zip tied any of the vacum lines? This may be a good time to o so.

Also check your IC piping.

Sounds like the ECU to me.

Boost leaks wont cause the car to bog, it's map tuned, remember? Get a volt meter and test the injector signals. If that's not the problem, go from there. It's a good start for diagnostics. Then check the map sensor.
