Looking for opinions on this. I just got my 96 T/A back from the dealer after having major surgery. Intake gaskets, timing cover gasket, optispark, water pump, thermostat, crank sensor etc...
Prior to the service, I was avergaing 20 mpg. I am now getting about 10 mpg.
I just made a 6-70 mile round trip on the interstate and burned thru half a tank!
Any ideas on what could be going on here?
Thanks
Wes

 

i would talk to tech that did tune up and find out exactly what he did and retrace all of his repairs
