hi guys been reading a lot of threads concerning the dreaded mcsf well ive had a dodgy batt for a couple off weeks but been good starter unless sat for couple of days but last week got half way to work ( 5.00am) car cut out and mcsf came on car refussed to start again was told prob batt problem so replaced it but no difference car starts & runs fine till it gets hot then cuts out without warning so bought a coder and this shows PO335 crankshaft position sensor "A" circuit is this just a case of changeing said sensor. any advice would be helpfull.
