Only feels vibration when braking and there is no fault in the engine, the problem is in the brake rotors , Feels vibration in the steering wheel, when applying the brake ?
SOURCE: Vehicle hesitates when you accelerate .
make sure you have the correct spark plugs(2)check the throttle position sensor on the car,as most people would be driving about with the throttle on the floor car feels fine.but as in normal driving anyone only uses the first half of the pedal and this is where most wear takes place and sometimes causes hesitation when driving.best of luck.

If you have had a bad enough problem with the fuel filter, and it is not the fuel pump I would have to say it is the injectors. If your car is fuel injected there could be dirt in the injectors in which case they will need to be replaced. The problem is you can flush the whole fuel system except for the fuel injectors themselves. Though I am not sure how to check them myself, a mechanic could tell you if this is the problem in minutes. I cant say for sure if this is your problem but I have a 79 corrolla and it is doing the same thing and since I have replaced almost the whole fuel line except for the injectors themselves this is what I am leaning towards. Good luck!

Have a Code P1811 on my 2002 Pontiac Grand Prix. The only thing I have noticed is it gets warm very fast. Haven't noticed any slippage with the tranny...What do I do??
