Jeep wrangler bucking

I have been having a problem with my 97 jeep wrangler.  sometimes when i accelerate my jeep starts bucking, almost as if it is not getting enough gas, and sometimes it also sound like it is backfiring while it is bucking.  also, when i go up hill sometimes i will be flooring it and will only be going 25mph, and the bucking and sounds will occur.  any ideas??? my 1997 jeep wrangler 2.5L bucks and when mash the gas it sputters, backfires and rpms drop like it is reving down really quick, and then cuts off. I have no engine codes, fuel pump and filter were replaced a year ago and i checked the injectors they were fine. someone please help me out. my email bamaboy_81@yahoo.com

How long has this been happing..one tank of fuel or more, could have been bad gas, replace filter,, put gas dryier in fuel tank..if it continues could possibly be transmission related..the reving down doesn't sound like transmission though if tansmission was slipping it would rev up..good luck

Jerking accelerating


similar problems: After 20min cool down jeep was bucking/lurching that I traced to bad o2 sensor in exhaust manifold (which you've replaced is seems). The second problem of bucking/lurching, backfiring under certain driving conditions I traced to the battery sliding into the computer wiring harness, disrupting sensor input / output signals. I cured this problem by placing a 1" spacer on rear battery clamp, pushing the battery forward. Been years and no return of problem.

1994 jeep wrangler 4.0 idles fine but when traveling cuts in and out and backfires when accelerator is pushed, i do have a cold air intake and jet performance module just recently added


1994 Wrangler with 200,000 miles on the odometer. Similar problem here: Severe bucking and backfiring, and engine misses when traveling down the road. I did an entire tune-up (plugs, wires, distributor, distributor cap, and ignition coil), but got the same thing. I thought it was dirty fuel injectors, so, I poured a bottle in a few times on fill-ups. The final solution, was a bad alternator. My mechanic said it was sending voltage spikes to the computer, causing the engine bucking and back-firing problems.

95 jeep wrangler splutters, jerks, backfires during acceleration


The ECU controls all of that. When they start to go bad they do very strange things that are hard to diagnose. They run about $300 bucks of you do it yourself. They are simple to do. Shop around because it is an electrical component and many places wont warranty them but some places do if your lucky you can find one. I also would not rule out your timing or distributor. I dont know you or what you have checked but could be the rotor or could be carbon tracking inside the distributor. Even the slightest crack in the cap can mess everthing up.

89 Jeep Wrangler when I accelerate it hesitate slow down its fine,accelerate it hesitate,and sometimes it will ****


Start by checking the choke. While the hood is up reach in to the carb and give it the gas.If the choke is normal then check your distributor cap for cracks(especially hairline ones,then check your rotor etc.
Best of luck

How do you know if your torque converter is bad on Jeep wrangler


First check fluid. Make sure it's full and clean and does not smell burned (compare to another good car)
Converter failure is usually most obvious when trans shifts to OD. if shift is late or makes bang noise going in, you likely have a problem. to check lockup, after od engages, lightly touch brake, trans should momentarily shift out of od. Whining is usually due to low fluid. Also check transfer case and both differentials for proper level and leaks.
