Car speed slows down and speeds up runs a little rough when speeding back up it does a jerk.


Dear Debbie,
Fuel filter costs about $ 20 plus installation, catalytic converter about $100 up to $ 600 plus installation..
Go for the fuel filter first.
If it is not that, do a diagnostic check before you do the catalytic converter.
The "cat" seldom is the problem.
God bless your efforts.

My Toyota Camry 1993 has a few problems. First off when I accelerate it jerks back then goes and sometimes when I let off on the gas pedal it will jerk back again as it slows down. Also my gas pedal...


Examine your engine mounts and the 'dogbone' at the top right of the engine. The jerking symptoms you describe do sound like a failed mount. The front lower mount is a hydraulic cushion type, and the chief sign of failure is oil leakage from it.

As to the wobbliness and bumpy ride, that sounds like the front suspension struts need replacement. You need good quality spring compressors to try that job yourself.

It is a crude test, but if you can easily bounce the front corners of the car up and down, and it keeps bouncing when you let go, then the struts are worn out.

2003 Expedition jerking/cutting out.


Had same problem: cutting out at low rpm, jerking, a huge clunk or shudder at higher speed (like transmission was going out), and rough idle. All these symptoms were intermittent.

CHECK THE FUEL FILTER!! Changed the fuel filter and thing runs fine!!
