i have a 1996 318i and have recently had a problem with it cutting out when up to operating temp??? i have replaced coolant temp sensor and repaired a slit in air hose from filter (air flow meter ) to throtle body ,, but the problem still remains i have also noticed that before it cuts out it only runs on 2 cyclinders 2 and 4 .... i have checked no,s 1 and 3 after cut out and spark plugs are soaked in fuel. if i clean and dry them put them back in and let it cool down it starts again runs for approx 5 to 10 mins then splutters and dies again.
please help

Sounds like worn piston rings or valve guide oil seals.

Cutting out... as in it dies? That's really odd. Dudesky, your thoughts?

thanks for the reply i do know a bit about cars / engines as i am also an owner of a 1972 vw bay window bus and have repaired it many times.
but in my experience if the rings or guide seals were screwed it would smoke like a rasta ??????
