Question about 1998 Jeep Cherokee
Just rebuilt the 4.0 put it in and started it up. let it idle to fill the rad. and when i tried to bring up RPM's it would bust out like intake AND exhaust valves were open. good compression on all cylinders replaced almost everything except flywheel and computer.......heeeeelp
Are you certain that you have the ignition wires hooked up to the correct cylinders(153624 from front of engine back, #1 on cap 1st post past the lower cap screw, clockwise) That's the only thing I can think of that will give you misfire in both intake & exhaust. Cap & rotor are new?
