Hi lads and lasses,

 

On my CR170 (71k) I'm getting small, short but frequent losses (not complete) of power in gears 1, 2 and 3 at low speeds, happening at constant revs and during gentle acceleration. The engine also idles unsteadily at a standstill. This doesn't happen all of the time.

 

I'm able to accelerate out of the issue. It seems to happen only at low revs, but can make the car lurch a little bit especially when trying to keep in at constant revs.

 

Car is into the dealership tomorrow to get its air-con and the door button fixed under the 12 month warranty supplied when I bought it, and I was hoping someone could give some more insight on the issue in case they try to fob me off.

Sounds like crap in the fuel. Replace the fuel filter + clean any residue out of the fuel filter housing + check it again.

Make sure you lubricate the new fuel filter seal "o" ring and be carefull refitting as they can leak
