Cb]Congratulations or your Morgan purchase![/b] Morgan trads seem not as easy to maintain as they were 40 years ago, but that is not true, merely the current consumer mind
training. You merely need new tools. All of my Morgans were/are Efi and I never required another mechanic unless I lived far away from the subject car, I have no formal training in
mechanics or electronics and no special abilities in this area I can think of. I merely find it all fun.

Forgive me, but what makes you think it is the lambdas? Do you have a diagnostic unit? That would be great. It is odd that two sensors would fail simultaneously. BTW, the
MMC does not carry parts for the engines they install. Relying on them does not help them. They have moved on.

😂 You are now in the same spot as an oversea mogger. Most of us too far from any Morgan dealer. In your case, be happy as most GEMS Plus 8s were sent overseas. A
substantial support network was created as Morgan engine providers contracts do not include engine manufacturer support for owners. They will not have much to do with moggers,
though many love looking at our engine bays. (wryly) Your car is also more than 21 years old..probably older than most dealer mechanics now.

It does not have to be. A lot of fellow Morgan owner work has gone before and that will help you. Of course, the GEMS variant has more things that can go wrong and parts are
harder to find but you have Morgan resources. Less used cars have more issues than regularly used one. With a little patience, you can cure all ills and save this Morgan from
the sad fate so many are condemned to these days. You have resources available to you. In your case, https://www.gomog.com/allmorgan/gemsPLUS8.html is a start. Try the
GEMS Manual(at the top) first. From its traffic since posted, it has been one of the premier aids for the entire world GEMS community (non-Morgan as well) for those two decades.
(Now there are also other helpful writings.) Think of your fellow moggers, this Manual and previous mogger experience as tools.

Another major tool is a GEMS electronics diagnostic unit. Do you have one? Yes, its expense is a PIA, but without one it is akin to working without a multimetre (buy one also) in
auto electrics.In fact, with the first Morgan EFI system, diagnosis only requires a multimetre! Do you have all these tools?

I dislike advising telling people to replace components without a diagnostic verification AND a check of the wiring. Too often people present an unsupported and wrong punchline
without describing the specifics of their problem.

BTW, Lambda sensors are generic..like spark plugs or tyres. You merely want them to match your wiring connection or you will have to modify that. (not hard either)
Google 77350 oxygen sensor UK and pick those with same connectors. Figure 50 quid each.
