So I have a 90 cherokee with some weird stalling issues. It will start and run fine in park or nutral but will stall when I put it in gear. Also when running if i touch anything electronic (breaks lights ect) it kills everything immediately like a short also wile running if i tap on or move my rear driveshaft it stalls. I have replaced the cps, distriburater, cap, plugs, wires, and countless other things. I also did some testing for ant shorts and could not find anything shorting out or drawing power. I'm really at a loss and its my daily driver so I really need to figure it out soon. tha
Hi there. Seems that the troubleshooting is leading to the transmission. When the vehicle goes into drive or reverse, if the transmission is lock up or the converter clutch is active, the engine will stall. When tapping on or turning the driveshaft and the engine stalling could be an issue with the chassis grounds and engine grounds. A ground will not allow the engine to operate properly. The wiring on the vehicle could be rusty and not make a good connection. If you need further assistance with your engine stalling, then seek out a professional, such as one from Your Mechanic, to help you.
How to Identify and Fix Common car Problems ?

The most common reasons a Jeep Cherokee engine stalling are the fuel system, the air intake system, or the ignition system. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
There are three major causes for a stalled engine: A lack of fuel, a lack of air flow and improper ignition. Running out of fuel is one of the most common causes of engine stalling, but dirty fuel injectors or a plugged fuel filter can also be the culprit. Your engine needs air to run properly as well.
The most common reason for intermittent engine stalling is a faulty crank shaft position sensor. This sensor relays engine speed to the engine computer. When there is no signal form the sensor the engine stalls. There are other items which can also cause this concern so please don`t just zero in on the cranks sensor.
Common reasons for this to happen:
An issue with the mass airflow sensor may manifest itself when a car starts and then stalls soon after starting. Fuel Pump Relay: The fuel pump relay functions much like a fuse for an electric fuel pump. The fuel pump relay engages as the vehicle is started and starts the fuel pump.
Some of the most common sensors that lead to engine stalling include the mass airflow sensor (MAF), engine coolant temperature sensor (ECT) and manifold absolute pressure sesnsor (MAP). The idle air control valve (IAC) and exhaust gas recirculation valve (EGR) are also well known for causing engine stalling.
When your transmission doesn`t have enough fluid, you may experience it stalling at red lights or stop signs. Though it should start right back up, taking your car to an auto shop for repair is key as your transmission lines may be leaking and may need to be replaced.
If the engine stalls while idling or driving, the engine may be running out of fuel or not receiving enough fuel pressure to keep it running. The most likely cause of this kind of stalling would be a fuel pump that is not spinning fast enough or is intermittently cutting out.
Common reasons for this to happen:
A defective TCS or torque converter solenoid can also cause this issue. Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine.
The most common sensor which can lead to your car stalling is the manifold absolute pressure sensor (MAP) or the mass air flow sensor (MAF).
There may be lots of reasons a car stalls at intersections, including low automatic transmission fluid levels, moisture in your gas, broken sensors, or issues with the EGR valve.
Typically, a vehicle will start and then quit because of an issue with the fuel or electrical system. It is important to monitor fuel levels as well as warning lights which can signal to the driver that a vehicle may quit unexpectedly.
Engine stalls are a common sign that your air/fuel mixture is off or your spark plugs need replacement. The stall can also be caused by faulty spark plug wires.
Bad solenoid may be causing vehicle to stall.
Stalling could be caused by faulty torque converter clutch.
The most likely issue is that a component is clogged. A clogged fuel filter is the most common reason, although a loss of power in your car could also indicate problems with the fuel pump or fuel line. Impurities or debris may be blocking the system, which causes the loss of power in a car.
If your powertrain control computer is misreading idle speeds, this can cause a high idling malfunction. When your car`s throttle is malfunctioning, this can cause your car to stall or idle high. Often this is a result of dirt buildup in the air intake. Other times it can be a problem with a cracked intake tube.
Faulty spark plugs can cause the car to exhibit starting troubles. Worn out plugs does not produce sufficient sparks, which is needed for starting the engine. This results in the engine to stall and fail to start quickly.
Will a bad O2 sensor cause rough idle and loss of engine power? You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling. Bad oxygen sensors disrupt all kinds of essential engine functions, including engine timing, combustion intervals, and air-fuel ratio.
Again, this is due to the computer not being able to meet the changing demands of the power steering system, causing the engine idle to drop too low. The engine`s computer will not recognize the demand for power, so it cannot compensate, causing the engine to stall.
Malfunctioning spark plugs can make an engine stop for a while and resume its normal functioning. It can happen when you are driving. The engine can also sound rough when idle. The misfires affect the proper functioning of your car`s engine due to failing spark plugs that have no power to ignite the fuel-air mixture.
The Jeep death wobble is a mechanical defect in your Jeep vehicle. The death wobble is caused by loose, damaged, or misaligned parts in your Jeep`s suspension or steering system. Due to the mechanical defect in your car, the parts can shake loudly or violently when you travel at high rates of speed or on rough terrain.
Immediately turn on the vehicle`s hazard warning lights. They`re the universal sign of distress. If you`re unable to pull completely over onto the shoulder, or if the car is stalled in a traffic lane, do not attempt to get out of the car! Similarly, never try to cross a highway on foot.
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
