1990 Jeep Cherokee Problems
Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.
A ticking type noise may be noted from the engine area due to an exhaust manifold that has cracked where the pipes are welded; cracked manifolds should be replaced.
The throttle body may accumulate an oily, black residue in the bore and on the throttle plate causing hard starting or possibly stalling when coming to a stop. The throttle body should be cleaned during regular maintenance but do not spray cleaners directly on or at the throttle position sensor (TPS) as this can damage the sensor.
The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.

1990 Jeep Cherokee Reviews
Bought my 1990 Jeep Cherokee Laredo new, it will be 21 years old in May, 2011. What a fantastic vehicle this has been. True, I don't drive a lot compared to most people, and the vehicle has been constantly kept in my garage when not being used. But the repairs have been few and not much above normal maintenance required. No accidents, a few very minor dings here and there, from shopping carts, mostly.
The Consumer Reports rating on this vehicle in 1990/1991 timeframe was about 6/10, so perhaps I just got lucky.
Also true, there are basic design problems with it, like the cooling system. The coolant recycle plastic tank has been replaced by myself 3 or 4 times. Various little things are gradually stating to fail over the past 3-4 years, which is expected. But overall - it's been the best vehicle I have ever owned and when it finally dies, I'll miss the damn thing.
That 232 CI straight 6 (4.0L) engine, is the same basic motor design used in the early 1960's Plymouth Valient and Dodge Dart for years - and those have easily gone 250,000 miles. Kinda scary...
