Hi my motor has this strange jumps all the time in any gear only when running does it stop. I thought it was the mounts so I cange one which was broken. It did not change, I also have bing using a fuel injector clearer each time refule the car.

What else could it be? what should I do?

MAS/Mass Airflow Sensor. How many miles on the car?

you should have probably changed both mounts and maybe the transmission filter...or it could be maf sensor..fuel filter...spark plugs...

I have recently change the spart plugs (month ago). I dont use the car daily I went back to my mechanic and he told me it could be because i change the oil to mobile 1 syntetic and the last owner was not using syntetic that it shoulg go away with time. Neither the MAF, Fuel Filter or Maf sensor have being change.

The car is a clk320 106000millies Everything is working great I have had it for 4 month's but only use it sporadiclly. The problem started one time the car was really low of gas. When I change oil, oli filter, spart plugs, air filter, air conditioner filter the car felt great, so i am guessing it was not the tune up.

What should I change next?

Another think I realize today is the car is letting out smoke off the muffler at start up.

wht gas do use use? use 91 or 93 whtever is highest in your state...smoke from mufflers im guessing you need a tune up plugs, wires, oil change..air filter? oil filter?

I used 93 texaco always, and I have just change the plugs and oil, air filter etc.. but the wires i did not change.

Mine sorta started what yours was. It felt like it was going to stall at a stop. My indy ran some tests on it and found out I needed the plug wires changed (they were starting to corrode). No problems since and idles smooth as Heidi Klum's behind.
