Car jerks sometimes when going from P to R

Sometimes (about 50%) when i put my car into reverse it will jerk violently and throw a check engine light. after this happens when i put it into drive I cant break 3k rpm. I have to turn the car off in Park and let it sit then restart the car and it works fine afterward. the jerk is starting to increase in frequency.

It's the transmission sensor. I've had mine replaced three times now. You can fix it (see this thread: http://www.suzuki-forums.com/suzuki-forenza-reno-forum/35284-transmission-range-sensor-all-you-need.html) and please report it to Suzuki at 1-800-934-0934

The is NOT a tranny problem.
it is an Engine/EFI problem
it is excessive RPM.
can be cause by many things,
1; bad ISC (dirty and stuck open) (or IAC)
2; air leaks (vacuum) to the intake manifold.
(to name just 2, of many) also TPS idle switch or mode bad.


"when i put it into drive I cant break 3k rpm"
i can not understand this, line. break?

if you have an 3000 RPM idle that is wrong, dead wrong.
they transmission clutch if fully engaged at that RPM and
will jerk on any car. How can it not.?
you could take the car to any shop that employs ASE mechanics
and ask them to Diagnose it. saving huge costs guessing and wasted time and veh. down time...

SOURCE: TRANSMISSION PULLS VERY VERY SLOW IN DRIVE AND ONLY WHEN I ACCELERATE HEAVILY. REVERSE WORKS FINE.

is this car still under warranty? if so take it back to the dealer and don't accept it as repaired till you drive it. sounds like the logic that controls the transmission is flipping out, sometimes they will tell you that it needs a reflash. what this amounts to is that the manufacturer put some not so great programming in the logic when they built the car but now they have a patch or fix that makes it work better but you have to pay them for their time to install the fix. ask them what they will charge you for the privilege and decide if it's worth it to you. there is a recorded technical service bulletin about harsh shifts for your car. well, actually there are two, the latest one a revision of the first. i would try to make this their problem, it really is. hope this helps.

Do you have problems starting the car?If no I have to ask.When was the last time you replaced the fuel filter on this car because this is what typically occurs with a dirty one . Camshaft sensor/crank angle sensors start showing problems starting up the car.It takes forever for the engine to catch They will also throw a code that a mechanic can read with a scan.These codes may not throw a check engine light so a scan is a must. good luck

For some reason my 98 honda accord 2.3 engine. Its starting to jerk slightly when I drive over 45 miles an hour nd I break to a complete stop thats when I feel the jerk. Sometimes the jerk can be harder...


Front brake rotors need to be turned and new pads. Adjust rear brakes. the front brakes are doing all of the stopping. (overheating the rotors, premature pad wear).

Jerking when car is in reverse


Check your transmission fluid. the car needs to be driven for about 20 minutes and you need to leave the engine running but in park. The fluid should be at least to the cold level and should be pink in color (use a white paper towel to clear the dipstick after you pull it out once and then put it back in again. If the fluid is dark and runny, start with a drain and flush to see if that does't help things.

Hi I have a 1991 Olds Cutlass Supreme, with a 3.1 liter engine. My problem is when the car warms at stops it runs rough. Sometimes shuts off. Sometimes when crusing at speeds 30-50 the car sort of jerks...


My 3.4 liter 91 Cutlass Supreme has similar problem when warm the engine misses (car jerks). But its fine at idle and without any accelerator pressure. The SERVICE ENGINE light also comes on intermittantly. I am going to test the ignition coils.

Ford Contour (2.5 V6 manual) jerks badly with throttle modulation


Check the lower motor mount near the drivers side. This usually is a problem with these cars. It costs about 140.00 or so depending where you reside. Also check the passenger side hanger bearing on the CV shaft if this is loose it will cause jerking too.

I have a 1997 trans port when u are driving it jerks and the faster u get the worse the jerking gets but when it is setting still its fine. when u go 10 or 15 miles it starts doing it so bad it turns off


You have bad motor or transmission mounts check it with someone stepping on the gas and the brake and have them put it in forward then reverse watch how much engine play there is or how far it travels back and forth if it's more than a half inch that’s your problem, if not post here and will give you the next procedure to check.
