I just put a rebuilt engine in my 92 wrangler, and had the trany rebuilt. the engine runs and you can drive the jeep. the problem is the speedomiter does not work and if slowing down for a stoplight as the rpm comes down when you put it in neutral it does not stableize at idle, it drops till the engine stalls. the electronic speed sensor and camshaft indicator have been replaced.

most cars will not pass emissions with out them. some places may also want the catalectic convertor on the car.

This sounds bad, even in neutral it stalls, you cant even push it. i would start by putting the transfer case selector in neutral and see if it rolls, if this jeep is only two wheel drive then start by jack the front wheels up and do this for the four wheel drive also, this is to see if its in the trany or the wheel, check and see if you can spin the wheels in the front, if this is two wd then if the wheels dont spin then you have a problem with the brakes but what concerns me is that it stalls in neutral, i would have to say the problem is in the trany and if this is a stick shift trany i would say the clutch broke and will not release but when its in neutral it should roll. anyway do the same in the rear wheels, jack them up and see if the wheels move, if they dont then remove the driveshaft at the rearend and then see if the wheels move. if the wheels turn with shaft off then theres a problem with the trany oor transfer case if its 4wd, if its 2wheel drive then its something in the trany, if the wheels dont spin with shaft off then start truck and see if it still stalls but dont let it go into gear with driveshaft off you will not be able to stop driveshaft when disconnected, just see if it stalls in neutral. good luck.

I dont think there are any injection parts in this 92 engine, just good old carburator. Which is most likely causing the surges. And you should definitely take it to the garage, it could eventuelly blow up and wreck the whole engine for good.

sounds like possible timing problem ( chain and gears or distributer or ignition wires )

If you have an actuator box on the passenger front axle that may be disconnected or broken. If not remove the cover from the front differential and check the gears...they may be broken.

the wiper needs to be tighten some more, there is a nut that holds the wiper to the motor tight that nut.

I have a jeep wrangler and to have it towed you are suppose to put the transverecase in neutral after you first depress brake pedal put trans in neutral then start engine shift auto trans into drive release brake pedal make sure there is no movement, shut engine off with key left in acc position shift auto trans into park, disconnect neg battery cable (damage can result in trans if shifted into park while transvere case is in neutral with engine running) you should refere to your owners manuel

it might be getting to much fuel check the fuel screw

I had the same prblm with my 1989 Jeep, 6 cyl straight, and it was because of the EGR valve, easy to replace and not too costly. EGR valve is screwed on the motor, driver side, and there is a ±1/2" rubber hose attached. Easy to see if device comes apart, cut by rust.

Could it be an exhaust leak? A minor one can make a ticking noise.
