so the information i recieved is as follows: cylinder #2
thus causing a change in crankshaft speed
. possible causes are a bad spark plug
, a vaccum leak
, an injector fault
, or high/low fuel pressure
also, my exhaust has a hole or a leak of some sorts around the cat that is in the middle of the chassis. it is creating a very loud and deep grumble and releasing a "hot, burned odor". so i am thinking this is a catalyc converter issue, im pretty good with cars and can install or perform almost any maintenance myself. i hate taking my cars to mechanics because i feel i constantly was overpaying for sub par service.
any help from other WJ owners who have dealt with this issue and dealt with it successfully would be greatly appreciated in finding the cause of the misfire code. then from there i know how to fix all the possible issues, mainly i just dont want to waste money replacing parts that do not need replacing.
note: just changed out the spark plugs to bosch platinum +4 plugs and gave her the first synthetic oil change. was running amazing until about 350 miles after the tune up. thats when the cat seemed to start leaking and the engine light came on and when im idling the motor has a slight constant rocking to it as if it is unbalanced and there is intermittent flutters of 100rpms during idle
