I have a 95 DE-T. relevant mods: t25 turbo, safc-II, blow through mafs, SR injectors.
Today I was driving and felt a little sputter around 4.5 grand, and then it was fine. Got to my destination, turned car off etc. Came back out, and drove about 1/4 mile and the car just died. I could still start it back up, but it would idle super rough, and only rev to about 2k, and sometimes just die. I played around with the mafs, checked the wiring, tightened all I/C piping clamps, and still the same thing. After a while it just started working again, so I drove about 100 feet , and it died again. Then I just unplugged the mafs, ran the car, plugged it back in, and it was fine and drove all the way home. Replaced the old o-rings on my injectors with the new stock SR o-rings. I then drove about 5 miles, running great, and all of a sudden it died again and idles rough. This is where I'm stuck now.
So basically: Rough Idle, wont rev past 2k, intermittent problem.
This just started happening out of the blue, today. I havent had any issues like this since I put the turbo on, about 3 months ago.
What do you guys think?

your maf might be telling you that its time to change it out...or there is a wiring harness problem. signs that you stated tell me its your maf or IC piping.
the wiring has been bugging me. Right now i have the wires connected with wire-nuts, but I am going to solder them tonight. Its been raining for 3 straight days here an I wonder if those splices got wet and started acting up?
I'd love to throw in another mafs, but I gotta find someone to sell me one. I doubt I can find any local, im in Milwaukee, WI

wont rev past 2k is a MAF issue. Either its dead or the wiring is fucked.
Rough Idle is common on KA's, could be excessively rough due to a vaccum leak or the maf is too close to the TB, or the orings but you fixed that possibility.
alright well today i soldered everything, i had wirenuts on all the mafs stuff. I wanted to make sure it was wired correctly before I finalized it. I'm hoping it was just moisture getting into the wires/nuts, arcing or something. I drove about 5-10 miles so far after soldering, and its been fine since.
We'll see if it holds up.
I also mounted a Fire Extinguisher in my trunk incase my amazing wiring skills fail me.

nothing bad wil happen to it unless u taped up everything good so the wires arent tuching but my car was doing the same thing till i decided to move the wires around the maf then found the problem i guess the pervious owner had cut the wires or something so i soldered everything n works perfect planning on switching it to a z32 maf anyways going turbo
