Could be fuel or ignition.
If the coil or ignition is weak, you may not have enough power to fire the plugs under load.
And if the fuel pressure is low, you may not have enough fuel under load.

SOURCE: Vehicle dies while driving-no acceleration possible

TRY CHECKING THE WIRE CONNECTORS ON THE PCM WHICH IS LOCATED ON THE PASSENGER SIDE FIREWALL. IT HAS THREE LARGE MULTI-WIRE CONNECTORS HELD IN PLACE BY THREE BOLTS. WIGGLE THE CONNECTORS WHILE TIGHTENING THE BOLTS CAREFULLY SO AS NOT TO BREAK THE FRAGILE PLASTIC ENDS. HOPE THIS SOLVES THE PROBLEM. KEEP ME POSTED PLEASE. THANKS FOR USING FIX-YA. GOOD LUCK

SOURCE: 1997 jeep grand cherokee. low idle 500 rpm, runs

Most of the time an engine is supposed to idle at 5-600 RPM in Driveif it's not you can up the idle. But you also may have a vaccume leak.

SOURCE: I have a '97 Jeep Grand Cherokee Laredo 4.0 liter that won't idle

Check your throtle postition sensor. It monitors what postion the throtle is at and sends that info to the ecm. It will go bad and cause that problem.

I've got a 1996 jeep grand Cherokee with the 5.2 v8 fuel injected Holley throttle body. My problem is while driving at soft or low acceleration it accelerates fine, but if you hit the throttle hard it


I would check the voltage on the throttle portion sensor with the engine off from idle to wide open throttle.If there are any dead spots, replace the sensor. If the tps checks out, you should check fuel pressure. If you have good fuel pressure, you may want to make sure there isn't a lot of slack in your timing chain. I don't believe you mentioned the mileage of your vehicle. Best of luck.

My 1997 Jeep Grand Cherokee Laredo is starting to have a ''slight'' hesitation after I shut it off and re-start it again. WHen I accelerate at first it hesitates a bit. I let off the gas for a few seconds...


A slight hesitation after engine shut off due to engine running rich meaning not meeting golden air:gas ratio of 14.6:1 so fuel residue in chamber continue to burn for the last moment. The same rich fuel problem that was why you had to let gas off during acceleration. Need to Check out the O2 sensor Check out MAP sensor Good luck

Battery dont charge


Check all the connections. The battery clamps should be tight. Wires on the alternator should all be tight. Have you watched your battery charge indicator when the Jeep died to see if it was falling below 13 volts?

You have a vacuum leak. Look under the dash and check the placement of the vacuum hoses that activate the vent doors. One or more may have slipped or may be cracked.
