Hard to start and stalling when driving etc.

Hi Guys

I am new to the forum and am hoping that some one may be able to assist with an issue which has been ongoing with our car a W168 A190 2000 model.

Symptom: Progressively hard to start, stalls at any speed from idle up to 100km/hr.

Thought dirty fuel as it was giving that indication so changed fuel filter and put in fuel doctor additive, issue arrived again a week later.
Started to misfire so a system scan came up with a fault code of misfire cyl 2 so replaced spark plugs drove ok still not 100% on start but was much better.
Driven for approx 40 mins to an hr car started to shut down (stall) at 60km/hr rolled for a while till it started again and no fault being shown via engine light.
Has gotten progressively worse now takes for ever to start, smells rich, stalls out at any time.When taken from idle up it does seem to misfire or something like a rev limiter effect at half throttle??????

So far have replaced Fuel filter, spark plugs (twice),crank angle sensor,coil pack, cleaned throttle body checked for vacuum leaks etc etc. still no fault code being raised but haven't taken back for another scan.

Great little car love to drive it but at my wits end as the only items to replace is the camshaft position sensor and big bucks fuel pump circa $400 ecu $500 to $1000..... ideas ?????

Welcome. I have no knowledge of these but the obvious question is which model is it - that might help with answers.

Had something similar with the wifes 2004 A160 when we purchased it over a year ago.

Ended up giving it to a mechanic who passed it on to an auto electrician. (Because he couldn't find the cause either)
Auto elec found some sort of gearbox sensor was giving incorrect information to the computer.
He replaced the sensor and everything just fell into place.

Later on the car was stalling for unknown reason. Turns out the "Summer/Winter" switch on the consol had coroded and again was sending misinformation down the line.

The problems with these W168 series is that the problems can come from left field. Somewhere you would'nt dream of looking.
I've had 1 or 2 little issues along the way and now, it just goes straight to the mechanic. (Who's a Honda specialist - go figure) He's solved the problems same day and most importantly.the wifes happy!
