Ok..i made a b18c swap on my eg4 and untill yesterday i had a chiped p06 ecu + a vtec controler.. And today i changed the p06 with a stock p30.. The engine is starting fine - no eror codes - .. But the engine is runing very rich - lean .. It has NO POWER until 2500rpm.. I cleaned EVERYTHING (throttle body, iacv, spark's , intake , air filter, dizzy ...).. Can anyone help me?
