When u crank it up it spits & Sputter u have keep foot on the paddel then it picks up the the fuel . already change fuel filter,plugs & wires.Also the radiator fan only works on high speed going down the road it works good when a/c on. This started when the battery cable ground 2 the body then fan came on. Has’t work right sense.
Is the check engine light on? pull the codes and post them.
Have you check all your grounds and wiring for burns or shorts? Check your fan relays.
