Monte Carlo Issues
my wife has a 2002 monte carlo SS with a 3.8 V-6. while accelerating between 40-60 it jerks like i am lettin on and off the throttle a little. its not a rough jerking by no means. just enough to be aggrivating. i have put new plugs, wires, air and fuel filters on it. does anyone know about what could be causin this? there is not any codes on a diagnostics computer. the fuel guage is floatin pretty bad too. would this be connected or 2 seperat problems?

It could be a plugged catalytic converter. I don't know why it wouldn't throw a code tho.
|
Just would like to say welcome to the Forum!
|
Not sure what would cause that... anyways welcome to the forum, hope you get it figured out. I find it strange that it's not throwing any codes

alrighty, thanks for the suggestions, i'll check it out and see. i did notice it has an exhaust leak about the middle of the car. forgot to mention that earlier. i'll check all that out. a clogged cat could possibly cause it to leak couldn't it?

welcome to the forum

The jerking sounds like a transmission problem, a lot of time tranny codes don't set off a SES light
Could be the torque converter going bad too Check your transmission fluid |
Might be a bad crankshaft position sensor. 3800 II's are prone for those going out.

Not saying this is the problem. But I had a 2 yrs old car that did the samething. I poured in some injector cleaner and took it down the freeway. Man I hit the nail on the head . On the way back from a 15 mile ride. I felt the difference right a way. So once a yr I put in a can of injector cleaner. Cheap fix if thats the problem. Hope its something easy & Cheap for you
