My 1985 GMC Sierra has began to bogg down and stall if I continue to drive it. The carb,pcv, plugs and wires have all been changed.
fuel filter maybe pump
Does it still have Cat. converter? And also change the fuel filter..
The only fuel filter I've found has been in my carb that wa changed when it was rebuilt. Will the fuel pump cause this seeing as though it runs great for about 20-30 and begins to bogg down?
it could how ever so could a miss adjusted carb, spark does it start back up right away after stall
