Recently bought a 2004 XT3 and would appreciate some advice from you guru's! When the engine is cold, it's a nightmare to drive on a light throttle opening in say 2nd gear in heavy traffic and is just really jerky. Once warmed up things seem to be back to normal. Could this be an O2 sensor playing up or is it likely to be a TPS problem? I bought it privately so don't have the option of taking it back to the dealer to sort out!

TIA for any help.

To start with, take the plugs out and make sure they are the proper iridium type. They are expensive but if not fitted the car will give exactly the symptoms you describe.

hi
it is not a sensor in question but poor injection giving no diesel fog before ignition. and once each cylinder becomes warmer -- the final temp at compression is sufficient to evaporate diesel injected before TBC/spark

@ anchorman, as it's only done 56k would it not still be on the original plugs?

I'll certainly check them as soon as I can; just remember reading something about them not needing to be changed until around 60k, so kind of assumed they're still the originals. I know, never assume anything :yes:
