All,

My '05 X3, just after ignition, was a little rough. I thought it was bad gas but the engine light came on.

Time to replace some fuel injectors or just run some cleaner through it?

Before you start replacing stuff or even assuming you know what needs to be fixed why don't you confirm what's wrong ?

Fault code reader.


Lumpy idle when cold often comes back to perished hoses for the PCV. To access them requires removal of the intake manifold. It is recommended to consider replacing the starter motor at the same time as they can go at 80-100k miles.

Interesting. Just had the PCV and hoses replaced last year. That problem also comes with black smoke out the tail pipe.

Ill have the code scanned.

Had the codes scanned yesterday. Bad gas possibly. Will try the injector cleaner. If this doesn't work I will clean the injectors myself .

I went to O'reilys and had them scan the car. Several codes can back and it was determined that 4 of the cylinders where not working properly due to possible bad spark plugs. Will install today.
