Need HELP ASAP PLEASE WITH SR NOTCHBACK

[seanforney]

Guys,


I am having a nightmare problem that we can't figure out with my car. Need any advice that we can get to fix it.

Motor, fresh swapped SR20DET Notchback Kouki Motor, FMIC, and Turbo Back Exhaust, other than that ALL STOCK!!!!

OK, the problem, car is running super rich, has almost like a couple certain spots, once it gets to a certain RPM that it starts to miss. Once it builds boost it cuts out.

We have changed the following: CAM Angle Sensor, ECU 3 times lol, Wiring Harness, Cool Temp Sensor, Knock, IACV, MAF 3 times, Fuel Pumps, Injectors, FPR, Have checked boost leaks, Spark Plugs, Coil Packs, Coil Pack Harness, Injector Harness, I mean we have literally tried everything, Compression is great....

Is there anything you all think we may have missed, please let me know, I have a drift event this weekend and am trying to get it running right.

Thanks in advance everyone....

Check your MAF wiring.

Done it, but cant hurt to check it again.

I can all but guarantee your ECU is thowing a code because the symptoms you're describing sound like the car is in limp mode. Just based on past experience I'm guessing it's the MAF wiring since that seems to be the most common reason for it, but check the code and it will tell you exactly where the problem is.

Ensure you are running the correct maf for your ecu. FYI it is NOT the same maf as a sohc ka or s13 sr. I'm guessing thats your problem since you said you swaped out 3 mafs. Usually most people only have one maf if they are running an s14 sr casue they are nowhere near as common.

Still nothing....

Start with the basics...double check the mechanical timing, then double check CAS timing when you put it in.
