**** - engine problem, quick advice needed!
Got a final 200 mile journey today to get my Spider back to the UK before I take delivery on my new one and the bloody thing is throwing a wobbler (it must know!)
Im leaving for Rotterdam in 3 hours so any advice before then appreciated!
For 99% of the time engine idles and revs fine - however every now and again it loses all power.
When revving the engine when stationary the symptoms are that it will very quickly drop 500-1000 rpm and then come back to the original revs - this happens in a cyclic manner 5 or 6 times before all is normal again. The drop is VERY sudden, not in a smooth up and down fashion like you might expect if it was a problem with air metering.
If youre on the move it manifests itself as a very sudden loss of power (almost as if the engine is going to cut out) and then immediately its back to normal - I guess you could liken it to pinking. Its very disconcerting when in the outside lane doing, ahem , 70!
The AFM is 6 months old and genuine, I cant see any obvious signs of air leaks on the induction. My other thought was throttle pot but im not sure if it would cause these probs.
Im at work but when I get home im going to do a battery and throttle reset but after that im out of ideas and worried! After today the car is getting laid up for 2 months whilst I put it onto UK plates, but I just really need it to make this journey!
