MG MGF Technical - MG ZR Engine Management Light - struggles at low revs HELP!!

Hello everyone! As a very new (yesterday) owner of an MG I am a touch disappointed with the engine - I have the ZR 160 which is the same as the trophy mgtf - has anyone else had the engine management warning light coming on and staying on with no discerable effect on performance? Obviously I am running it in and have not exceeded 3300 RPM (apart from one instance were it just got the better of me!!) The light came on for fifty miles then went out and when taken back to the dealer no fault could be found. As soon as I got it home the light cameon and stayed on for 100 miles with the engine, on idle, struggling to keep firing and cutting out - even blipping the throttle did nothing. PLEASE can anyone help as the dealer couldn't find a fault and I am a bit worried! (I also put Super unleaded fuel in - long shot I know!) If anyone has any ideas thoughts or equal experiecnes then let me know! Thanks guys - and I have to say my god this MG doesn't half handle well! To finish can I say that the sales team at Priory MG Nottingham (Mansfield Road) are the best team I have ever come across - Richard, Stuart and Robin moved heaven and earth to get the car for me - many thanks to them and can I whole heartedly recommend them for your next MG purchase!

Many Thanks

>> Roger,

New one on me, it certainly isn't a 'common' fault, sounds serious though. Get it checked out and keep going back 'till they find something. Sounds like an intermittant MEMS failure to me, could be something as simple as a dodgy sensor sending 'wrong' signals to the MEMS and thus causing it to default to 'safe mode'.

My advice to you is to get the dealership to replace the MEMS first and see if that helps. If it doesn't, then one of the sensors is likely to be to blame, again replace under warrantee.

Good luck and let us know how you get on OK?

Thanks for the advice - as it happens the problem was a sticky throttle cable potentiometre!! Too tight to start with an after slackening off appears to have solved the 'jumping car' syndrome! It is now almost run in and contary to certain car shows/magazines seems to have lots of torque and handles like a flipping dream! Well done MG and thank god that something is challenging the Japs for a decent small rocket ship! (Oh and it looks better in yellow!!)

Cheers Guys


PS How do I go about joining the MG owners club?

NOTE! Cut and paste the address (it contains a ? and this BBS gets confused by them!) :-)

Glad it seems to be sorted out and that you're happy with the car (was thinking of one, but i am too big for the car, 6'2" and er, well, lets just say overweight shall we?!!!) ;-)

I am also 6'2'' and am just able to fit snug in the seats! Perfect fit although any taller and it would be impossible - I am 13 stone though and the seats are a touch restrictive but very very supportive and people who are of larger stature than me have said they are extremely confortable! The latest development is the fuel gauge flow line is being replaced!! I coaxed the car to a garage at the bottom of the red to find that I had about 2-3 gallons left!! As for the mileage I have been getting 30-31 mpg anyone else got a lower than expected mpg?

Cheers again
