Dear Mini experts, my mini needs your help! i'll try and keep it brief. Over the last year or so my mini has had a problem with stalling the minute i take my foot off the accelerator. I've taken it to the garage and sometimes they fix the problem but only because when they have taken it apart, and found nothing, they put it back together and it miraculously works again. which makes me think its most likely some dodgy connection somewhere, but where? its not the control valve, its not the ignition coil, its been plugged into the ECU and it shows no problems. I only drive it to get it to the garage and back and it coughs and splutters until its going at least 40 and then it evens out a bit, as soon as it slows it starts to cut out again. It was o.k ish before the MOT and service, which it passed, but on the drive home it had this problem again. No one seems to be able to work it out, and not having a clue about engines myself i am going broke trying to get it fixed. Any ideas? last time my mini had a long running problem you lot fixed it, which was brilliant, please can you do it again, before i have to buy a boring 'sensible' car to get around in! Thanks, Jayne
p.s its a 1998 rover mini cooper mpi
Hello Jayne, I'm no electronics bod but if it were mine, this is what I'd do. Take it to a local garage that you know and trust and while it's on their machine thinggy or even initially, their exhaust gas analyser, stick it on the brake tester (it's only a dynomometer that acts as a road after all.......) and as it's on there, get a plastic coat hanger and start faffing about with all the wiring. A bit of pushing and pulling here and there won't do it any harm but if there's a weak link or intermittent wiring harness fault anywhere it WILL upset the electronic balance and show on the screen.
The next Q is this. Where do you live? and then, can any local; forumer tell Jayne where she can go locally.
But whatever you do Jayne, please don't go down that horribly sensible and boring road to perdition and get a horribly sensible and boring car. Tell yourself a hundred times '.....Peter says that I deserve better'
Are you there Jayne.......... There is also a possible answer to your querie on a thread about the MAP plug.
We're all trying to he;lp but no reply is a bit..............
Peter! im so sorry i didnt get back to you, thank you for your reply, its not apathy its just id seen quite a lot of people had viewed the post but no one answered for a few days so i asked and looked elsewhere, also i keep forgetting my password so if i think of it at work i cant log in! James has been helping me and we thought we'd found the problem but unfortunately we tried the new sensor plug today but its made no difference, even though it was that very plug that seemed to be effecting it when we wiggled it before. I do have a brilliant local garage but i think if i put my Mini in front of them again they might cry, they've already tried to find the problem before and to no avail. Dont worry, i wont be swapping my Mini for a boring car, i'll keep looking for the answer and let you know when weve found it. Thanks for your help. Jayne
Hi All , and Peter, I have been trying all I can to help Jayne with this prob, see my post on MAP plug. I have read some bizarre random suggestions like 'change wiring harness ' as this is pretty easy'..like ****** it is!!!....and anyway that may not be the prob...Sir J.........still trying!
Hello Jayne Just a simple thing but have you tried a good quality fuel injection cleaner treatment through it yet? It sounds like an injector is either spraying poor or slightly blocked. Most car part shops will have one they recommend (normally a bottle will treat about 20 gallons but just add it to a full tank and give it a good run, normally its about 50 miles before it will show up an improvement. The most common wiring faults on MPi are bad earths in the engine bay, and water behind the fuse box. Apart from the chair on the passenger side damaging the loom it sits over I think they are not that bad for silly electrical faults.
