Hi Guys, first major problem with my car that I've owned for 15 years. Car was parked up for a few weeks and then I took it out for a spin,ran fine for about 40 minutes and then it just cut out on me,started to idle really rough,,would not pick up on the revs at all. Left it for a while ,I cleaned the plugs and it started,running really smooth, but now it only runs for about a minute then cuts out again. will not pick up on the revs, and a very rough idle/misfire before it shuts down. Sensor of some sort??
