gc 5.2 sputtering/bucking/backfiring
i decided to give my 5.2 a tuneup a couple weeks ago so i went out and got basic plug wires, cap and rotor. i did it all and ever since then my jeep runs like ****. if i accelerate slowly it will buck and and backfire and it also does it when im cruising so its impossible to drive the highway. if i accelerate fast or floor it , it will run fine and strong. i do not have any lack of power by the way and i changed the wires but still has same symptoms. How can i test my tps? is there anything else that would cause these symptoms. thanks
