Yes. If the timing is off all kinds of bad things could happen. Have a mech. check it. As well as get your Jeep check with a ODB computer.
What year Cherokee? XJ or Grand? Engine?
If you have overheating issues I would look to the cooling system first especially if you have an early XJ with the closed cooling system. (Pressure bottle on the firewall & NO radiator cap on radiator.) These early systems are sensitive to ANY leak in the system and will boil out coolant if there is a cracked bottle, leaking cap etc. Also, those systems are now 20+ years old & likely ready for a new radiator. Just be prepared to examine the system front to back if you have a RENIX XJ that has not been converted to a newer system or had the early system rebuilt. (Early system is fine so long as you maintain it. Aftermarket replacement parts are still available at this time.)
It is almost impossible for you to get the timing "off" in an XJ Jeep Cherokee (or Grand Cherokee) with the 4.0L inline 6-cylinder engine. The 'distributor' (not really a distributor but skip that for now...) has a lock-down tab on it which prevents you from 'adjusting the timing' by advancing or retarding the distributor. DO NOT GRIND THIS TAB OFF! If someone has pulled the 'distributor' out they may have put it back in 1 tooth off - generally won't run other than to spit and fire occasionally.
Renix XJ's (1990 & older) have no OBD port that you can read outside of using a real-time analyzer (Sun Analyzer, etc) at a dealership or garage. No Codes are generated or saved on Renix (pre-HO) XJ's.
HO XJ's (1991 & up) all have OBD1 or OBD2 depending on how new they are.
