If the muffler shop cracked the carbon canister, that could be causing a leak. Check the canister for leaks. Use the soapy water trick.

Is that JWT ROM tuned for Z32 MAFS? Stupid question, but you never know...

My friend had a similar problem on his SR20DET, horrible whack idle, richness up the ass and NO LEAKS (we literally did everyting and anything that could have been done to any and every location that could spring a leak)... turns out there was a plug on the harness that was loose, he pushed it in and it was all gravy.

I doubt thats the case for you but its something to look into.

Good luck man

I'll check that tomorrow. I figured that if it was leaking I should still be able to rev fine.

Yes. I have heard stories of jwt actually messing up recently and tuning for the wrong stuff. Prolly rumors.

Checked and double-checked. Wires were also checked for right splicing.

Thanks for the help.

tighten up the bov a bit? injector/maf issue with ecu?

seriosuly, check maf.

I ran the car again tonight.
Checked bov
checked tps
checked mafs...I used a multimeter grounded to the battery. The feed from the battery was right ( 13V ) but the 0-5 volt line read the same as the battery. I'm guessing this is 90 percent of my problem. I don't know what to do besides clean it with electrical contact cleaner or whatever that stuff is called. If anybody has any ideas on fixing the mafs or anything else please let me know.
