My monte carlo is a barrel v8. I have a problem, when i start it and it is idling it runs fine but when i go to put it in drive and try to run it it pops at the catylytic converter and it back fires and turns off and then it is hard to turn on. I have changed oil,oil filter,fuel pump, rubber hoses coming from carb, plugs and wires,distrubitor cap and rotor,fuel filter, and rebuilt carberator. I need help timing is adjusted as well.
all has been changed that I think is the problem do you guys think the catalityc converter is bad or a timing issue?
