SR struggles and dies out...

I have a problem with my black top S13 SR, there is dark black smoke coming out from the exhaust, engine struggles and studders and won’t rev past 2000-3000 rpms, engine than shuts off at 0 rpms. What could this be? I changed the spark plugs- not it, could it be the MAF? Could it be the EGR sensor? Maybe broken cylinder or valve? Injectors? Someone please let me know…thanks

MAF

3

it is something alone your intake.

the same thing will happen if you have one of your major IC pipes loose, the mafs not being plugged or malfunctioning will also do this.

4

What else could it be besides the MAF?

5

Massive vacuum/boost leak

ignitor on the way out

faulty ECU

Injector stuck open

timing way off

CAS fried

no compression

Take your pick

6

check the codes on the ECU

I fixed the problem guys, it was a tube from the SMIC that came off when I was driving, it was hidden behind the actual intercooler core so that’s why I couldn’t see it. But I found it and put the tube back on with newer clamps. Thanks for all the tips and info. guys, you really helped me out! Thanks again- P.S Special thanks to Varun, Bing and Michael Lee (Racing Revolution) you all helped me out a lot.
