Car Forum / MINI / December 2003Help!! 50mph max.
Hi there , I was on the motorway today when all of a sudden I lost power on my mini city `92. The car started shuddering at about 50mph and wouldnt accelerate any further. On changing down gears it still felt a little unhealthy but managed to keep going at about 45mph in 3rd until I could stop. I checked the oil which was fine left it for 10 minutes then started again and it seemed to run fine back to my house. Does anyone have any Ideas what would cause this?? Cheers Liam you dont say if the car is fuel injected? jono  SignatureBarspeed Mini`s - Devoted to the Classic Mini "Persisto Transverbero Adversum" Email - barspeed@hotmail.com The Rover Mini Se7en Register - http://www.geocities.com/minise7en2001/ Barspeed Mini`s - http://www.barspeed.co.uk/ Barspeed Mini`s Group - http://groups.yahoo.com/group/barspeed Barspeed Classic Cars - http://www.geocities.com/barspeed3 If you have received this email in error please click below. http://www.nobodyhere.com/justme/nose.php3 > Hi there , > [quoted text clipped - 8 lines] > Cheers > Liam maybe it is a vaccume lock, the fuel system cant suck enough fuel from the tank therefore starving the engine of fuel check if the tank has breather pipes if so are these blocked? have you recently put a new fuel cap onto your car that could restrict air getting into the tank? i am assuming that you have made no recent modifications to the fuel system that would hinder the performance of the car. one way to test if it is a vaccume problem is to remove your fuelcap straight away when the problem occours you maybe able to feel strong depressureisation when the cap is removed try driving a short distance (assuring your tank is not so full the fuel will spill out) in exess of 50mph. hope this helps minimad Remove the air filter element, and give it a try, Fitzy > maybe it is a vaccume lock, the fuel system cant suck enough fuel from the tank > therefore starving the engine of fuel check if the tank has breather pipes if [quoted text clipped - 9 lines] > hope this helps > minimad fuel filter is prolly blocked makka > Remove the air filter element, and give it a try, > Fitzy [quoted text clipped - 18 lines] > > hope this helps > > minimad This is an odd one, but encountering identical symptoms, it turned out to be a dodgy low tension connection to the coil. You should probably try the other suggestions first though.

Damp can cause the engine to start "missing" on one or more cylinders, causing a huge lack of power and lots of "shaking". Check the over-all health of the ignition system (points condition and gap, state of leads, state of plugs, etc) and give it a good helping of WD40 Dan > > Hi there , > > [quoted text clipped - 18 lines] > > Dan But thoroughly clean off the WD40 at the first opportunity.

It should only ever be used as an emergency measure. Collecting dirt I am inclined to believe in... But WD40 *causing* corrosion? That's the first time I have ever heard of it - It's been a while since I had science, but if I am not mistaken, corrosion happens because water gets to metal (h20 -> Fe) and oxidises (FeO). WD-40 (Water Displacement formula 40) is supposed to keep water away from metal, so unless it doesn't actually work, I don't see how it can cause corrosion. By all means - I might very well be wrong - but it does seem a tad odd.

Errosion might be more accurate. WD40 is a pentrating oil, it works kind of like an acid and kind of "etches" away at things... or so I'm told!

I never use it to spray plug leads or anything like that, because of having to clean the mess off afterwards, but I'm not so sure about "acid" and "erosion" - the makers claim it is a rust preventative!

A clean sparkling distributor cap and leads are the best thing to have on the mini's. WD40 will etch machined surfaces. rm >Hi there , > [quoted text clipped - 5 lines] >then started again and it seemed to run fine back to my house. Does >anyone have any Ideas what would cause this?? Mine did this recently - was a burned out amplifier on the distributor. Signature<{---Celeborn---}> Natural laws have no pity - RAH |
