HELP!!!!!!
I have a 1989 jeep grand cherokee v6 automatic, started backfiring in the throttle body and lossing power, when starting up you give it some gas it will die. Ok I have put new fuel injectors and fuel pump on it and new spark plugs and wires, new alternator,new air filter,new TGR value, new fuel filter, have checked the exhaust values , timing, replaced the catalytic converter, I have checked the piston rod they are fine.
I am stuck as to what it could be any ideas or help would be a blessing.

backfires threw the intake happen when eather... a valve is hung open burnt, cam lob gone.... or when there is not enough fuel... and the spark/flame go hunting past the combustion chambor....
check the crank position sensor ?
