When you step on the gas pedal it hesitates during acceleration. Does it sound like fuel filter needs changes or spark plugs?

I replaced the battery and I still have starting problems / starts when jumped
but won't start afterwards / cleaned neg battery cable but no luck / can you help?
This has been happening fort a few weeks

I have a coolant leak but I always keep some in it.

After reaching 40 miles per hour, transmission starts jerking. Happens more often once car warms up. Mechanic said it was because of unmatched tires. Ours are same size, just different brands. We don't believe this!

either have a lifter bad or rod bad, what is the cost to replace either? Do not want to replace the motro, need to get thru the winter with it.

for couple of days didn't want to start right up, then it died while driving turning a corner and after sitting 30 min finally fired up ,but while trying to start it there was strong smell of gas coming from tail pipe. A day later it wouldn't fire over at all "crank no start" now after messing with it spraying wd40 while cranking it over it starts"ruff" but then keeps clean steady idol. Also have some interior electrical issues when turning my steering column clicking under dash with blinking lights, could electrical have anything to do with my "crank no start"?

First time this happened I was driving a trailer from PA to TX. I just got into Texas, it was very hot, and the Jeep started bucking violently. Engine light went on. I found a Jeep dealership, they read the codes. I forget which cylinders and injectors came up. 1 guy told me is was serious, another guy was awesome, he said I could safely get home 7 more hours. I let the car cool down, it got me home.

Since then my Jeep has been to 5 repair shops since August 2016 with multiple misfires (bucking), each time a code comes up it is a different set of cylinders/fuel injectors.

What I can do to cause the car to buck.

Hot day
AC on while towing a trailer up a hill

Mis/bucking starts at 60 mph. I can get it to stop by backing off gas. If the engine cools down it will also help. If the AC is off it helps too.

Even the hot day and AC will not always create the problem.

One shop did fuel cleaners, fuel kit, new plugs, new air cleaner, it improved mpg, but did not fix problem.

The car has been in 2 shops for 2 weeks with them trying to replicate the problem.

Anyone out there have similar problem?


Thanks for any help.

Check engine light comes on and off. It will crank up and go dead and ECM has what looks like oil in it

smoking after driving for 5 minites

The 15 amp fuse keeps blowing. I found a bare wire and fixed it but not certain that was problem. I would like a diagram on all fuses and the proper area it's for?

No check engine light on. Car drives perfect until i stop at lights. Feels like its going to shut off. When drive its fine. Rpm drops to 500

I filled it up with gas and it started missing, then, it would start and go dead but will crank right back up. It also back fires from time to time. I replaced the crank position sensor and have done a few tests on it. All i have seem to have found is it looks like oil in the ECM. I have never seen anything like it. What do you think it might be.

Also the same Mechanic told me I needed a rear end.

the mechanic said I needed an oil change. Ieft the truck there with him. Only for him to call me back to say my transmission is bad.

Only Happens/Hear it When I Step Hard On Gas Pedal From Standing Still , Take Off in 1st. Gear

I bought this vihicle brand new and have only owned it for a year and 3 months. My lights come on and the key remote works, nothing was left on for it not to start. It makes a click when I turn the car over but nothing else happens. Please help

i park next to another jeep it will disable there jeep to unlock or lock. i pull away they are able to unlock and lock there jeep

top of rear shock is not connected to anything what part do I need besides shock? bracket and or any bushings??

I had a thought about my dome light filling with water during a heavy rain. Maybe the drain tubes aren't large enough to handle that much water at one time? I wonder if replacing the drain tubes would work? Has anybody tried?

Roars a little and a little vibration also kind of hops a little when backing up incline parking brake doesn't seem have any tension on it not sure if it's rear end or possibly ebrake hanging

ABS light on, hooked up my ABS reader and it says can't communicate, check connections and make sure key is on.
Even tried my Superchips to set for tire size, same message can't communicate. Why can't my readers communicate, and to what module?

fluxuate about 250 up and down while idling and driving most of the time, not just when the faults are showing.

Did not disconnect battery.

Removed the fan shroud.

Removed the serpentine belt (I did remove 2 pulleys to alternator and the one to the right and put them back on. Not sure if this would throw anything off?)

Removed old water pump by taking out all bolts (I think there were 7 total), disconnecting rubber hose containing radiator fluid to the left and rubber hose on top of water pump, and metal hose to the right (unsure what this was).

Connected new water pump and reconnected all hoses and bolts.

Put on new serpentine belt.

Put fan shroud back on.

When I went to go crank the engine, ignition cranks, but will engine will not start. I used jumper cables from my other car, but it seems it won't hold and dies really fast.


I did some research online, and saw some people saying that I could have messed up the timing? Is this correct?

Losing power fast, did I mess up something with the alternator?

Any help would be great. Thanks.

When I push down the 4x4 lever,it quiets down a little,and the part time light stays on all the time. Had a hard time taking it off of 4 wheel drive last time I used it,but the jeep runs good,just worried.

Take off throttle body hose oil n the air filter

After it the throttle body was replaced it started but why I cut it off it didn't start no more an why was oil n the air filter compartment

What can I do to find out the solution an source of problems

It happens mostly when I am traveling above 50 mph and when I slow down to around 40, and then speed back up to 50.
Sometimes it also happens when I am beginning acceleration. I have 60,000 miles on it.

runs worse or just a bad. Has a bad miss. Compression on cylinder ok. driving me nuts.
