c200 w202 hunting on idle and stuttering

[Tinkerer]

Well .... if it is the same one as fitted to the C220cdi ... you could come and see me (Long Stratton area) and play swapsies that might rule it in or out. Part no. is A 611 094 00 48.

how can i tell if it is the maf, once ive done the coil pack

vv

it is very likely to be the maf.
Meter pin-5 wrt gnd, expect ~2v at idle rising to ~4.8v at full revs.

I know I am being a plank DM, I get the pin 5, I get the gnd but what is 'wrt' ..... be gentle with cos I know it will be so obvious!

hi im having a problem with my 1999 Mercedes c180 1.8L petrol.
i fitted a 02 sensor and a camshaft sensor a while back but its still showing up as faults,
i was told it is because i bought them cheap on eBay and the o2 sensor is a split cable so i had to join them and im thinking this might be the problem,last week i replaced the water pump and i know there not a fast car but there was a Hugh difference but every now and then its like the car goes into limp mode and goes all sluggish like im driving a 10 ton tank,then the following morning its fine again,here are the results when i plugged my computer up to the car,any help would be great so thank you for reading and i hope i posted in the right section.

this is only some of the photos wont let me upload anymore

O2 Sensor issue

Hi there

im hoping this is the right place to put this, i have recently bought a c200 s reg merc and the only thing that is wrong with it is just like previous posts is mine is running sluggish and every now and then you go to accelorate from a junction and it just has no power so i have to take my foot off accelorator and press it down again and away it goes.

also when traveling along it seems to suck back on power as well so i have had it plugged into 2 different diagnostic machines and the first one came back with o2 oxygen sonsor mix stop/ too lean or somthing along them lines so i went and bought a new sensor and had that fitted and then got the codes reset but was still doing exactly the same thing so then had a mobile merc tech come to me and he used there equipment and came up with the same code message.

the MAF sensor looks new and (excuse me i know nothing about the correct names of parts) is it the air intake flap looks really new as well, clean as anything so now i dont know what to do?

im going to send the sensor back as i think that might either be faulty or not compatable with my car as it was a universal part and they said it would be ok but obvioulsy not and eveything points back to the o2 sensor and no matter how many times i clear the fault as soon as the car is started then it comes back.

anyone got any ideas plz

is the Maff that you have fitted a bosch one or after market? did you have the Maff fitted or was it on the car when you brought it!

sounds like Maff to me
