Sounds like you need to check you spark plugs, wires, cap, rotor, ignition module.. I just replaced all of these on my truck and solved this problem. Though, you may want to check them 1 by 1 because you may only need one of the other.. all simple things to check if you have never done it before.. if you have done it before, then it should be no problem to you at all! Probably wouldnt hurt to go ahead and change your air filter while you;re in there working on you truck, that is if you havent done it in a while and it looks fairly dirty.

Pops while pushing the gas back fires smells like gas shakes while pressing the gas on 91 jeep cherokee l 4.0


Pops, while pushing the gas pedal, and back fires and smells like gas and shakes while pressing the gaspedal, on 91 jeep cherokee l 4.0
spark timing way off. or burned valves.
i dont think a 4L can change cam timing. (gears)
that is gross misfire,
so bad it backfires to the throttle body and air cleaner
in all cases is bad spark timing, or worse burned valves.
bad rotor & cap,?
doing a tune up get rid of that carbon tracked bad cap.
and timing magically works.
ever do a full tune up this decade or in last 60,ooo miles>
?

What causes shaking while accelerating


Mrs Amanda when you said on pushing the gas pedal is shaking do you mean the whilst accelerating with engine running ( reving) you do receive a shake? or when pushing the pedal you do feel on the pedal with engine off a shake? If it is the first check for any spark plug or spark plug HT Lead not working and cause the engine to shake. If is the second cause then check for your pedal connection cable etc.

ENGINE HESITATES WHILE ACCELERATION

LOSS OF ACCELERATION


It can be fuel pressure issue or it's the problem with accelerator pedal or its clogged filters causing there.

There are many other possibilities. I suggest you to go through the list of help links mentioned below, these will help you to confirm where the actual fault lies: -------

HI my 94 mazda protege was running fine untill 2 days ago,when I started it in the morning after few minutes on the road(warmed up) it started hesitating and sputtering when accelerating. noticed when...


when my cars do this I check the fuel supply first.....should be a small filter near the throttle body somewhere that could be prob. then check electric/fuel related items. there are several different items with these symptons, nearly always related to fuel....go to a good websight like autozone repair guide for help....also a haynes or chilton manual available at parts houses will save you lots of bucks----i never take my cars to a garage...this is general info, but i hope it has helped...

The upper intake gaskets may be leaking. They are made of plastic and metal and will leak air. Do not remove the cover on very top of manifold when changing.

Hesitation on acceleration engine runs fine otherwise


My 99 Audi A4 2.8 Quattro was havinga problem starting at times. It would idle poor upon start and then it would come up in rpm where it should be. I had hesitation from a start and after coasting for more than 5-8 seconds, the car would shake violently upon acceleration at about 1/3 throttle. I cleaned the Mass Air Flow Sensor. This helped but did not solve all my problems. I then replaced the Mass Air Flor Sensor. Little to no change there ($108.00). Lastly, I replaced the spark plugs. I bought Bosch plugs ($4.82 ea.). This got rid of all the symptoms. I had bad lugs and possibily a dirty MAF!
