Help!!! My 325i runs fine when cold but as it warms up develops a strange misfire. Have changed leads, plugs, rotor arm and cap. Also changed temp sensor (blue one) and checked air flow meter. new fuel filter and cleaned k&n element. oil and coolant look good. happens mainly after getting up to around 60mph and then it gradually gets worse.
All out of ideas now!!

This is just sat at idle after driving about 10 miles.

econometer swings to the left as revs drop?
