If you barely push the throttle and it's sputters, try unplugging the EGR valve and see how it runs.Make sure you have vacuum to the EGR valve.Start engine and on the outside see if you can put your finger under the EGR valve and see if it sucks up. Be careful and not let the engine get to hot when you do this test.

SOURCE: acceleration hesitation

Depends how long since your last tune up and mileage. I would do a normal oil change, oil filter, air filter and plugs. If she still does it, try checking for a vacuum leak. Start the vehicle and spray "lightly" carb cleaner around your vacuum lines. If you have a leak the engine will increase in idle suddenly. Replace the line or part. AS A LAST resort and pretty rare is the distibutor. They usually run about 75.00 to 110.00...hope this helps.

SOURCE: Poor performance, hesitation, sluggish and shaking

Those are cylinder misfire codes. PO300 is random misfires (meaning 1+ cylinders misfired) and the other 2 codes are for cylinder #1 and 2. Did you change the ignition coils yet on 1 and 2?

Do you let the tank go to empty before refueling a lot?

SOURCE: 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.

Hesitation is usually a dirty throttle body and idle air control motor.

1989 jeep wrangler wont start it was running today for a while


Check the carb out sounds like its pushing to much fuel in butterfly could be stuck or choke on constant any warning lights on the dash i.e. engine managment light this could be the lambor sensor in the cat if this sensor has gone then it could be telling the fuel system to push more fuel in.

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

89 wrangler get warm won't idle the takes along time to restart


These jeeps are carbeurated, with heavy emissions systems forced down the throats of Jeep. There are insane Vacuum systems that are too complex to deal with. What I did, (I have the 4.2L) was go out and purchase the Weber kit. I am not selling the part for them, I am actually a happy owner. Mine would die every time I came to a stop. I swapped out the junk and popped in the Weber. I have had no carb problems what so ever. I even eliminated the messy vacuum system! I payed about 200 bucks on Ebay, but from Weber direct they cost around 300. Good luck!
