Yea Scott my normal mechanic sent me off to the dealer cause he thought it may have been the actual engine sensor, however, the dealer is telling me its the distributor itself. They quoted me $1100 to do the job and Im thinking that seems quite expensive. My mechanic is now sourcing me a distributor and I would be surprised if the whole job took more than an hour to complete. I would also think that a second hand distributor would do the job as this is quite a rare thing to happen apparently.
