im located about an hour south of tampa i tried unplugging the ecu and battery it cleared the codes and the car ran great except for a lil extra smoke due to over fueling i think its a grey ish color.... and way it ran awsome then a check engine light came on and i lost all power.... but if i just eased on the gas it took for ever to get to four thousand rpms but after that it runs great.... all i did was block off my egr valves engine vacume. any more tips
