slow roll problem

Hey guys, do you know what can cost the car to have slow rolls going forward? When ever I releast the gas pedal from a stop, the car will go only 2-3 mph. It almost feels like my car is breaking on its own But not to a complete stop. When I jack up the car, all my wheels are free from locks or any breaking.

My car will not roll forward more than 2-3 mph from a start. It feels really slow. Kinda feel like someone is pulling me. Like I up shifted at low speed. 3rd gear At 5mph

Did you try the same thing except manually shifting into first? Does the same thing happen?

Try a throttle reset too.

It also feels the same when i switch to manual shifting. when ever i lift my acceleration pedal under 20 mph, it would slow down instantly(light breaking on it's own).

I think I experienced this in my coupe. Basically when you let off the gas pedal and let the car coast it feels like the car is being slowed down by the engine. Like engine braking. I also checked my brakes to see if the tires spin freely, but I don't think it's the brakes. Its probably the load from the engine and the all the accessories and supercharger that is making it slow down faster.

I know that my C230K sedan can coast for a while longer than my C32K. And my C230K has a wheel bearing that is going bad too so it is making some noise, but it still drives fine.

hey bro,
it happened with my coupe!

try the throttle reset, or changes of oil. Did you ever change your tranny oil, brake fluids, etc?

it feels like as if you put it in "cold" mode and u can basically let go of your foot at a stop, and the car wont move at all.

Did you ever get it fixed?

I had a new tranny in my car last year. All oil in my car have been changed last year(break, engine, tranny). I think this engine braking is the reason why i get 9.5 mpg in the city.

It sounds like your throttle position sensor, or pedal travel sensor may be going bad.

As others have mentioned, I would try a pedal reset, then a trip to the shop if not successful.

Going to send my TPS to BBA Remanufacturing next week to have it rebuilt as they are VERY expensive. $400 plus 7-10 business days.
