Ok guys since i have gotten my car back up and running its been throwing a check engine light, i had a code 1 and a code 21 well i grounded the engine and the code 21 went away but the code 1 stayed. Well i drove the car to work and back (roughly 80 miles) and the car started cutting out really bad and sounding like a subaru, i pulled the codes again i had a code 1 and a code 43(fuel supply system) so at that point i went and got a new o2 sensor, replaced it but still running a code 1, no more code 43 though.

Now for my main issue, when my cel is on (code 1) the car runs and idles normal no issues, but when my CEL turns off (this happens when i shut the car off for a few minutes then turn it back on) the car idles super low, super super rich and cuts out at cruising speeds. I am confused by this and dont know what the hell the deal is. Car is running stock p28 crower stage 2 cam, aem cam gear set at zero, dizzy set at tdc, edelbrock intake manifold, b16 throttle body, stock fuel system. Please help me as i want this to go the frick away.
