hello members, i have a 91 EF std. got a b20 swap with CRX SI harness, LS matifold, b20 throttle body and injectors, distrubutor. running on PR4 ECU. My friend and i did the dpfi to mpfi wiring. Right now i have a problem where my motor fires up and it will shut off right away. on the ecu there was a code 10 but i replace the sensor and that went away and now is not throwing any codes at all, any luck or tips on what i should do? Thank you very much.
