Arright guys, I'm looking at this 1997 Volkswagen Caravelle VR6 (don't ask), which has a 2.8 engine, don't know which other cars that engine sits in. Anyways, the guy who's selling it is a bit of a self-made mechanic type. The problem is that sometimes the engine suddenly loses around 40% of its power, before it goes back on 100% again, which ideally shouldn't happen obviously. Is this a common problem on these engines? The seller said this might be that the power switch for the fuel pump was bust, I'm not going to trust him on that though. Also, the engine vibrates when at high revs in 3rd gear, he said this might be because one of the engine mounts was close to breaking. Does this take a lot of work to fix? Anything else I should look out for on this car? It's been an ambulance before, gone 244 000kms, although the engine and transmission have been replaced and refurbished within the two last years, with initially around 70k on them.
