    Car has been running with no issues EGR had a small leak on connection to my SD headers so I put some RTV on it last night after getting home from work...did not unhook anything just applied RTV around connection...went to go to work this morning car would start then die within couple seconds...applying throttle would keep it running for a extra second or two and would die...pulled codes on my Aeroforce and it is throwing po520 po443 and p1133...I have had zero issues since I installed the SD headers couple weeks ago...front and rear o2 sensors have ZZp extensions and are ziptied away from exhaust...Anyone have any thoughts?

    My first thought is maf, but I have to go search out what each of those codes stand for.
    I drink..so consider that when reading my posts.

    P0520 Oil pressure sensor malfunction
    DTC P0443 Evaporative Emission (EVAP) Purge Solenoid Control Circuit
    p1133 = Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor 1

    Looks like it may be a vacuum leak, O2 issue or maf.

    That's what's weird is it ran fine with the egr leaking and now it won't stay running with the leak fixed...anyway the o2 took a crap and is causing it to not stay running?

    No because your O2 doesn't take over until after at least 10 seconds. Insufficient switching means it's not goig lean/rich like it should. Easy way to test is unplug it. Don't beat the car..but see if it'll stay running.

    You probably leaned on the maf when you were fixing it. Personally I'd try the things I suggested. Especially since I'm me, I always like my advice.
