Rough running on V230

[marknexus]

Hi everyone!

First time posting on the forum as i have just become the proud owner of my first merc!

However(!) I seem to have a problem with the running of the vehicle.

It is a P reg V230, 62k miles auto.

When cold the engine runs like a dream, however when hot, it starts to misfire, runs roughly, lacks power and spits and pops back though the intake. It also seems worse when the car is under load.

I am suspecting (hoping?!) its either a plug or more likely the igniter pack breaking down - but would like some more advice before starting work!

I have a few other issues with the car but they will be posted seperatey under the right topics!

Thanks in advance for any help and advice offered!

Hi Mark and welcome,,can I just query when you say V230

Yeah its the 111 engine

The most likely cause is the throttle flap faulting.

get the codes read first.

Thanks for your input guys. I changed the plugs and one coil and it seems (touch wood!) to be behaving.

If i have a repeat problem I will get the codes read as suggested.

Thanks again!

v230 with a misfire

Hi guys

I have a 97 v230 petrol that has developed a misfire? I have changed coil packs, ht leads, plugs and had the ecu tested, the ecu tested fine but i still have the misfire. It appears to disappear above 4000 revs.

Any one experienced this before, I understand that these have alot of history with the ecu so I was totally shocked to find that it tested fine??

Hi , there can anyone let me know the best way to get at the plugs and coil packs on my v230, do you have to take the inlet manifold off or???
