mazda 323f 2001 y reg runs perfect then cuts out when trying to restart misfires.
 

Hi new to this so here goes purchased a mazda 323f Yreg knowing it runs perfect then after a while cuts out and wont start if you try for a bit its hard to start and if it does run it misfires and runs very rich while misfiring if left for 5 mins runs perfect again ive change the M.A.F sensor (mas air flow) which there was no change ive changed the cold start sensor and the fuel pump and filter so im left with the coil packs or the cam sensor or the crank sensor , ive read other posts on here with people with the same sort of issue but there hasnt been no response to say if fixed or not i like :D the car but my patience is wearing thin :mad: can someone shed some light on this thanks.:cool:

Have you checked for any fault codes?

When was the last time the spark plugs were changed?
