1989 jeep Cherokee Laredo timing specs and how to

I have a 1989 jeep Cherokee Laredo and bought it as a non-op. owner said it overheated all the time. so far the things i have fixed are... replaced the thermostat, water pump, radiator, the head, valves and all that they entail, spark plugs and wires, distributor/rotator thingy and cap, new gaskets on everything previously mentioned plus the intake and exhaust manifolds and oil pan. when i finished and started the engine for the first time i found that is misfiring really badly. it barely can keep running at idle because its so bad. the plaque inside engine compartment says that TIMING CAN NOT BE ADJUSTED. if that is true then i would like to know what else could cause this problem. but if it's not true... i guess my question is How do i check/adjust the timing on the 4.0 liter inline 6 cylinder and what are the specs that i set it to.

    ya, i have manuals, own a timing light jeep uses a chain which cant slip and has not broken. the specs are not in the specs are not in Chilton or hayse which i haven,t found one by any other producer and shouldn't need to. also neither go into much detail other then to say that it is set at the factory and to have a jeep tech adjust if ever should be needed. i cant afford to let someone else work on my car. so anyone else got an answer or advice (other then the obvious).

the easy way would be to check the bulbs elements if 1 of them is burnt all u have to do is replace it.then check the brake switch which is under the steering column u cant miss it the brake peddle rests against it when not being pressed down,which is how it works too.also check all the fuses.if all else fails start checking wires.

1989 Jeep cherokee Laredo over heating and the fan wont kick on, plenty of water in the radiator? How do I check to see if it is the thermostat sticking closed?


when it's overheating check to see if the lower radiator hose is hot. if not therm is bad. If OK, check temp sensor on thermostat housing. signal from there goes to the computer, then to fan relay to turn on fan.
