My 1989 vette is having problems, hard starting, low idle bucking, and popping.When RPM picks up the car seems to run smooth.Fuel milage has dropped to between 12 to 14 mpg.
So far changed fuel filter
pinned computer got code 12(all clear)
checked timing
Checked for fuel leaks (NONE)
looked it over for frayed wires
New thing it did yesterday after running small trip 10 mins
wouldn't start checked the fuel valve on on rail and had only air come out for 2 seconds like it was starving for fuel or fuel boiled?
Will stop at A/Zone today to check fuel pressure
Does anyone have other suggestions?
