Help! Fuel Trim problems I have just re installed my ls1 back into my firebird.....I have done something wrong. It will barely run just sitting, and will not handle a load of trying to drive....I have a scan tool to monitor different factors, the fuel trims are crazy. The car will run fine when da fuel trims are idle around -+1% then the long terms will max out both positive and negative until the car finally stalls? I have no vaccum leaks and 02's are switching fine? I'm stumped, any advice?
