My car is shaking when I put it in reverse and a little bit when in drive. Prior to this I changed out my plugs and wires and the car was acting up by backfiring and shaking violently.


I am thinking that with the back firing ans all ,you put the ht leads on in the wrong firing order and had 2 wires crossed
when replacing the new with the old you fixed the cross wires but reintroduced a bad plug or a bad ht lead.

My 2003 ranger 2.3 is idoling rough and sounds like its backfiring in side the engine seems to run fine when i accelerate


Could be that your cat is clogged up,the way to check is to remove and look in both ends,mine clogged up and caused my head gasket to blow between cylinder 3 and 4 on my 85 Nissan 720,part of the inside came apart and was blocking the air flow,causing my exhaust plugs to blister.

Shakes ONLY under acceleration? Goes away when you back off of the throttle? Are you sure?
Please inspect the front and both side engine mounts.The half shafts will cause that sort of a shake(whole car) when they go bad(inboard CV joints).
Aggravated OR caused my a motor mount that has shifted to one side,binding the half shaft.
Common in Chrysler mini vans!!!!!!That is why the front motor mount is adjustable.
Check the engine mount on the short half side first.

2001 ford taurus, 3.0 vulcan motor. just rebuilt the whole motor, backfires out of the intake, seems to be out of firing order. i triple checked my work and can't find the problem. whistling sound of...


Back firing out of the intake is because the valves/cams are not set right. When you did the timing belt . did you set the crankshaft mark at top dead center of the compression stroke. If it's at the exhaust stroke this would cause backfiring and violent shaking.

My 2002 chevy impala shakes whem i accelerate the gas between 40-60 mph. I changed the tires and 2 motor mounts but it still shakes


When you changed your tires were the wheels inspected to make sure they weren't bent. If on of your wheels is bent even just a little it could cause your shake. You could try rotating the front ones to the back and see if it makes a difference. I would inspect your wheel bearings and front CV axles and joints. If one of those it bad it will cause your shake.

common causes for back firing, low fuel pressure, or restricted injectors, breakdown of secondary ignition coil, internal ignition coil arching, or a dead spot in throttle position sensor.

Wheel shaking?


There are many things that can cause front end vibrations, I will give you a list and hopefully the information provided will allow you to narrow it down. Usaully front end shake is caused by a tire that either has a shifted belt in the tire or the tire weights could have falled off and the tire and wheel must be rebalanced, another reason for shake is if the shake occurs when applying the brakes it is a warped rotor and the brakes must be replace in the front end along with new rotor installed, the last thing that it could be is a loose or worn out front end part perhaps a tierod end. If i was you I would try rotating the tires from the front to the back and see if the shaking goes away if it does it is most likely a bad tire (shifted belt) or the tire needs to be rebalanced at a auto garage. after checking that first then jack up the front and grab the wheel and move it back and forth up the down to check for play or loosness, as I said if the shaking occurs while applying the brakes replace the brakes and rotors.

03 winstar won't start, shakes ,back fires, fires 3times dies.


More than one issue, maybe? Also consider other experts' solutions.

First, it sounds like the EGR valve is sticking open. The exhaust valve is supposed to be closed when idling, otherwise open. It recirculates exhaust back into the manifold; can't idle car very well when the valve is open, but should not cause backfire.

Backfire, is generally an ignition timing issue: the ECM (electronic control module) is responsible for that. Check it / replace it.

Worst case: small break in one of the head gaskets (not likely, but symptom is the same).

Vacuum leak, too???

Hope this gets you pointed in the right direction!
