My car has recently started to stutter a lot and feels like its misfiring. At idle, it sounds rough and and you can hear the engine stuttering slightly. When driving it, particularly at lower speeds, it hesitates as you put the foot down and splutters its way through the rev range. At higher speeds out on the motorway it runs better as long as you have your foot planted otherwise its doing the same thing (stuttering) as at lower speeds. It's a pain when trying to move along in slow moving traffic.

Recently changed all the plugs a few months ago and all still look fine. VSS needs replaced and I have a new one but surely that wouldn't affect the running to that extent - especially as its doing it when idling??

Any ideas before I start replacing every sensor in the engine bay??

Thanks

Sorry, I meant to state that in first post.....no, the problem appears to get worse as the car warms up.

That may explain why it gets worse when it warms up. £69.43 from Euros right now....probably wouldn't do any harm to change it though.

Mine ran like crap when I had issues with the green temp sensor.

Ha!....you mentioned coil packs which gave me an idea. I swapped all four over with a known good set and problem solved! It's running as it should now
