Why is it that my 2003 Base Acura RSX is jerking when I step on the gas for a quicker acceleration? It jerks but doesnt really make a sound. And It just isnt a smooth acceleration. Feels as if the V-T

First thing to check is engine /transmission mounts. A fails mount would let the engine rock in the engine compartment and would be able to feel as a jerk under accel and braking. Also check for play or wear in the CV joints on the drive axles.

have you checked your fuel filter first, then check your fuel pump

hi,

check the transmission fluid. if its not this then I would suggest taking it in to a parts store to have the codes pulled on it..jm

Sounds like a basic miss or fuel problem.
Have you had the computer scanned for trouble codes ?

try checking fireing order of spark plugs sounds like some wires may be on the wrong plugs if this was helpful please give me a good review

If you means you press the gas, then for a second it doesnt move, then it jerks into movement, you need to get your transmission checked. If its not that, It could be electrical or you are just pressing on the gas pedal too hard when you go from a stop.
If you are say, going 30 and accelerate up to 40, and somewhere in between like say 35, it jerks, you have a SERIOUS transmission problem. Take it to a mechanic and expect to pay $$$$.

1ST THING YOU NEED TO DO IS CK TRANS FLUILD ON FRONT SIDE OF TRANS AND MAKE SURE IT IS NOT LOW,AND MAY ALSO START BEING SIGNS OF TRANS ISSUE,NEED TO HAVE CK BY TRANS SHOP IF FLUILD IS NOT LOW SO YOU WANT DO ANY MORE DAMAGE IF CASE OF TRANS ISSUE,HOPE I WAS A HELP

Sounds to me like the timing is off! it COULD be bad gas though! run that tank through, and refill, then see how it feels!

There will be screws in front and one or two pointing down on assembly.
You can go to autozone.com and register for full free online repair manual for your acura. It has diagrams and step by step directions on everything. Plus much much more

Regarding the heating issue, sounds like your thermostat is stuck open so the coolant isn't heating up. (May need replacement) Does your engine temp guage show it running colder than normal?
