P103 issues Hey guys,
I have a 73 Corvette with a 5.3 swap. I've gone through 2 different MAF's and still throwing the code. With the replacement it was running fine, but started running like *** after giving it a WOT acceleration to around 90mph. Now has P103 and idles like dogshit and stalls frequently. I've erased the code, and it immediately comes back. Any suggestions?
Car has a 228r car, 799 heads, a fast92 intake/tb, stock 02 85mm MAF.

Can you post a log and a tune? What is your Mass Airflow Sensor (Under Engine Diag, airflow tab) fail frequency set to? That's what will cause this code. Stock setting should be 13,500 khz, on a 0411. What PCM are you using?
