Thread: Phoenix Area SR20 Gurus!

Anyone interested in helping to diagnose and fix a stock RR SR20 in a B15 SE? I want to give it one last shot before we put her on the selling block but I'm running out of ideas, time and patience. It was turbo'd with all of the essential B14 parts then put back to stock. It now misfires like crazy for about 10 seconds before it dies. I want to get it to daily driver status and it needs to pass emissions. I'm in the North Valley and this is the car:

Thanks!

if you want to bring it by my shop in chandler I can help you out.

I would love to if it drove lol. Northside to Chandler sounds like an expensive tow unless you know someone that can get it there.

im always around to help turn some wrenches buddy.. let me know! hows the timing plugs and wires looking on it?

I swapped all of those from my working SE and still no go. Thanks for the offer...I may take you up on that.

Check all your inputs...maf tps o2


Hook up a scanner and figure out what your long term fuel trim is

what parts did you change exactly when it started misfiring? Things like injectors, MAF, etc. If one of those, could be injector O-Rings or bad MAF. Check the codes to see what it says is malfunctioning.

sounds like a simple fix. just trace everything down.

I replaced the engine harness, entire intake manifold, ecu, fuel rail, MAF, fuel pump, and everything else that goes to the intake manifold. I am getting a few codes; P1320 (ignition signal primary), P0180 (fuel temp sensor) and P0105 (manifold pressure circuit). I havent pulled the rail yet but checked it before I installed it and it all looked good. I am having a hard time finding the time to do all of this and either a second set of hands or someone that has a shop would be helpful.

Hard to tell from those codes where to start.

Have a scanner?? You need to check all your PIDS and make sure everything is reading somewhat within range. None of those sound like a misfire besides the MAP circuit and the primary side, but not knowing the b15 ignition system differences from the older chassis, I unfortunately cannot tell you where to start without seeing the system.
