My 1999 Chevrolet blazer 4wd. 4dr. 4.3l vehicle has code po452(evaporative emission system control sensor). Can it be checked without dropping the fuel tank? I have read online from another person's post that this could cause automatic transmission to not shift properly while driving. Is this all true?
have the same problem?
