My 4/4 has been fine in the 6-8 weeks of ownership but today, on starting her up, the engine was missing and sounded really rough. The engine light has come on too.
The dealer says that it might be the 'limp home' mode, as I've travelled over a couple of speed bumps at the local school

He's asked if I'm happy driving it until they can have a look, which is fine if it is purely the limp home mode - but what if it isn't? I don't want to bugger the engine up driving it if there is a more significant problem.

Not sure what to do now but think that I'll ask Life's to collect it and investigate.

How do you avoid this kicking in again?

If the ECU has gone into limp mode you won't want to drive it anywhere, it won't do more than around 30 mph. The most likely scenario is the connection to the MAF sensor has come loose or got some dirt into it.

You can buy an OBDII reader from ebay for 30 odd quid, that will tell you which sensor is causing the MIL light to come on. Which model 4/4 do you have?

1800 Zetec (black top)

Well I've left her parked up at home and the dealer is collecting her monday afternoon.

I did fire her up this morning and the problem ws still there.

Of course it would be just as a fine spell is hovering over the North West right now.

Well initial findings are that the fault is mine alone, although it's going on a diagnostic thingy in the morning.

When I've washed the car, I've thrown some cold water, from a bucket, over the bonnet to wash off the suds etc.

The water has dropped through the louvres and flooded the channel where the plugs are.

Hope to get her back tomorrow.

Embarrassed or what.......

Ah yes, did no-one tell you about that? It's a good idea to put a bit of plastic sheet over the engine and under the bonnet before washing. Lots of god Morgan advice is available at TalkMorgan, Mog Group (Google groups) and MogTalk (MSCC discussion group)

No one mentioned it and I didn't think it through really. I didn't even read the section on TalkMorgan!

Life's collected her, changed the HT leads and plugs and all without charge - even though the fault was entirely mine.

What can I say - except excellent service and thanks.

Embarrassed - oh yes!

Glad its all fixed, I had the same issue with my CVH 4/4 earlier in the summer after some pretty impressive rain. A new set of HT leads sorted me out - didnt see your thread til today.

The thing that puzzled me is that I have been out in torrential rain before and usually rinse off suds with a watering can and it never caused a problem before.

The CVH engine, being SOHC, doesn't collect water like the Zetec can. When I had the CVH in mine I never had a problem either. Now I have the Ecotec, I am a bit careful, but the plug cover seems to keep everything nice and dry.

If you are thinking about buying a Morgan at the moment, then I would say do it, you can't lose. Second hand values are very high at the moment, so you can buy one now, secure in the knowledge that if you decide it's not for you and you sell it on after a few months, you'd lose hardly anything (you may even make money, depending on the model).

Of course, if you do decide to go ahead and buy one, what will actually happen is that you will immediately fall deeply and irrevocably in love with the purity of the driving experience it offers, and become a complete Morgan addict like the rest of us.

I suspect you're right..... smile

You will also need the patience of a saint and the lower back of a well tuned athlete who does piltaes on a daily basis!

Re the 'limp home' Couple of years ago, mine ( 1999 ZetecE) went into that mode just outside Alencon on the way back from the LM classic. I tried all the obvious stuff ( plugs etc) but in the end it turhed out that a mouse had crawled into my air intake and munched the air filter element! ( We were staying at the Arbor which many of you will know is in the woods off the Mulsanne and surrounded by trees and grass)

Needless to say, I've now fitted a mesh over my intake and also changed the filter for an ITG - apprently mice can't stand the taste of the spray.

How do I know it was a French mouse? - Mike Duncan insists that when he took the thing appart thos bits of the mouse that wre still in there had a striped jersey on!

This really is a true story!

If it gave up and was eating cheese, there's your answer right there....

Are Morgans bad for lower backs?

Try one for a long test ride.

I don't think its the seat comfort itself, more the climbing in and out, especially with the hood in place.

Personally, I avoided using the hood whenever possible.

The seats are usually very comfortable, but getting in and out with the hood up can be tricky until you learn the knack of it. I have covered well over 400 miles in a day in mine with no problems whatsoever.

But you definitely need to take one for a long test drive - ideally maybe hire one for a couple of days, if you can. If you've not driven a Morgan before, you'll not realise just how different they are to drive from a 'normal' car.

If I buy one, I doubt the hood would ever be used... Particularly as we're all suffering with drought conditions here. smile

One thing whih does, I think, allow any owner to try and get a ride which has the characteristics which suit him or her best is to fit Rutherford adjustable dampers ( these can be adjusted very easily on the car.

The hood/ entry and exit thing is a bit of an acquired taste. I'm a mere 6'3" aqnd I manageg it OK although it aint so easy with the hood up
I bought my present car from Mike Duncan. Mike and his son Ben are both about 6.5" so my question as to whther I could get in and out was very quickly disposed of!!

One thing I did do wa to drop the driving seat by taking out the wooden blocks on which the seat runners rest. This means that I'm a litle deeper into the car and I don't get the wind blowing over the leading top edge of the screen right in my face

Have a chat to Ben. They have new stuff coming in all the time and if you have any speciific requirements in mind, he'll look baut for you
usual disclaimer- just a satified customer

if you DO decide to take the runners off, it also involves a little bit of alteration to one of the seat flanges but it doesn't affect the integrity of the structure and is easily done
