Hi guys so after a little help bought the 04 plate streetka February this year and had a slight misfire every once in a blue moon last week this misfire got really severe so I had the coil pack plugs and leads changed still no different took it back to the garage where he put it on the diagnostics and changed the cat converter. So drove away from the garage and the eml came back on the same day and was spluttering and misfiring like never before!! Just wondered what else there Is I can do to get this fault sorted! Gunna try getting it back to the garage tomorrow to get the lambda sensor changed. Any help would be appreciated thanks

compression test ?????

before you throw any money on parts guessing the problem have a live diagnostic scan done. this will let the mechanic see what sensors are reading etc.

were the plugs changed along with the coil pack and leads?

ok well excuse that bit on my post, i obviously missed that bit out when i read the post.

Yeh all changed and been on diagnostics again today which showed a fault with the lambda sensor! So had this changed by the mechanic and ran like a dream for about a mile then started to misfire again! To be fair it is now only slight and only does it in second or third gear when not fully accelerating ! Starting to think this was a Friday car when it was made :-( thanks again guys

Definately a Friday car and not worth keeping for years like I have mine - I loved it when I got it, but they all have the same issues, I had the coil pack replaced last year (or maybe the year before?) Hope the issues get sorted for you
