I have been reading post trying to figure out what the possible problem could be...I am even more comfused than ever before...I am not sure if its the fuel pump or pressure....opti..or plugs and wires...I would like to get a reference for a good b-body LT1 mechanic who really knows these cars as I dont have the time to get it running like it used to...I was getting about 22-24 miles to the gallon I might be getting 12 now...it stumbles ..idles rough...and you can hear it missing through the exhaust..please recommend a good mechanic or someone knowledgeable...dont care if they are working out of their back yard...just dont want to replace every part in the car trying to find the problem
