Engine/Transmission Missing problem
Iím having a problem diagnosing a missing issue and need some advice. I have a 1991 Bronco with a 351 EFI engine and auto 4 speed with OD on the dash with about 72,000 miles. When Iím driving at speeds around 35 mph or more and then let up on the gas to slow down a bit, when I press the gas pedal again, I get what appears to be a hard engine miss. Usually just one, but sometimes two. After that the Bronco accelerates just fine. It ideals great, runs strong, only this one issue.
I brought it in to a carb shop and they put in a new EGR valve and gate, they also vacuumed out the intake system. They checked everything possible and said itís perfect. When I got it back the miss is somewhat improved but still there. Does anyone have any idea what could be? Could it be the transmission causing this miss felling?
