i have a 1988 350 TPI in a 1956 bel air. it has a painless wiring harness, the engine is rebuilt and every sensor is new. it has a new computer too, but the original prom. it keeps throwing codes 32 and 36. mass airflow and egr. both are brand new. any ideas on what would cause this? it always idles at about 1800 rpm unless you kick the throttle once then it goes down to 800 but as soon as you get on the gas again it idles up again until you bump the gas pedal once. the linkage is not binding up. i checked it. also, now it has started to miss out really bad while accelerating or just cruising around. it acts like its running out of gas or sumthing. the fuel pump is new too and the pressure checks out. any help would be great! thanks
