my son just got jeep,it looked nice has bfg 35x12.5 on 10.5 rim.
he drove it just around block..than next day found it wont go over 40mph..
exhaust leaked and intake..my son had tried to replace gasket.
thats the best I can say..he called me..
I come, open hood he starts it..engine shakes so bad it wants to fly out.
its a mess.
I find 2 cyls not firing by pulling plug wire while running.no change in rpm with wire off.
plugs fixed that..
I only did cold compression test..125psi all 4.
than I find tps .has 5v..than.18 volts to 2. 4 on tps travel.
I replace and now have .email@example.com on tps travel.
it starts,stays running,high idle, just lack of power under load,no backfire,but u can hear bog and spuddering in exhaust.
times it feel good,,, cold start and go you will hit 5th @ 45 as if it was fine than bog starts
I smelled thinner vs gas when I took carb off for tps..
I have tank out now..and checking sensors,
