This is the error code which comes up on diagnostics and having thought that perhaps the new one I bought was a dud I put another one in but still no luck.

Drove about 3 miles this morning and it ran like a dream yet on the way home it was jumpy and sluggish again.

Its definately intermittent for sure!

Ive read in here about the possible earthing problem with the MAF but has anyone else had similar problems and found it to be something else?

The only thing I can see beyond the earthing problem is the ECU.

Planning on giving the earth on the MAF some beefing up a bit and will see what happens but if it was that then why would the crank sensor keep showing on the diagniostics?

Even when cleared over and over it was the only thing that came back up which is odd...
