Lums begining to scare me...
Hey,
For a while now my car, 1993 genesis 1ltr Lum MKIII 4 speed has been acting wierd.
Unfortunately it is quite hard to explain, especially for someone like me! but here goes...
When she is idle she will be on like 1000 revs, the longer she is left like that the revs go down and when they get to like 700 she kinda jumps and shots herself back up to 1000,its almost like she almost cuts out and then something brings her back to life.
Thats not a problem but thats the best way I can describe the 'jump' which she also does when i am going at any other speed, usually when I'm revving high, like going 70mph down the motorway, she'll do this wierd jumpy thing like shes gunna cut out and then save herself, she only did it lightly at the start and not very often, and at random times! but its getting scarier, shes also taking longer to recover from her 'jump'and she is doing it more often. And she seems to lose power after the jump.
She also does it when i put my foot down, for example if i get stuck behind something, slow down and then when i get the opportunity to overtake and put my foot down she can do it then, and she just seems to have less (and thats saying something!) tork (sp???)
It really does feel like one day i'm going to be going along the motorway at 70 and she'll just cut out and not recover herself....
anyone have any ideas?? its really odd.
thanks

Your earth straps all ok Rach?
My dad did say i should change the plugs..
I think I'll get the haynes manual/nextdoor neighbours dad out this xmas.
What are earthstraps?? I tried googling to no avail. Although some nice shoes did come up in images....

you'll want your earth straps secure or you could melt your ECU
(i've caused that)
thinking on that subject, i was going to say maybe some injector problem (not putting enough fuel in for some reason), but given what the car did following the ECU cockup (blasted the entire fuel tank into the engine thru the injector), maybe a poor strap is scrambling its signals in a subtle way and making it run badly.
or maybe its just getting old and needs tweaking. mine would sometimes splutter a bit from cold in winter, and the design is theoretically susceptible to carb icing if the inlet heater fails
then again its literally been years since i touched any of this so it could all be b*ll*cks

Well, it happened... Right on the M5, just at a fork in the motorway, right in the middle! LolIt really does feel like one day i'm going to be going along the motorway at 70 and she'll just cut out and not recover herself....
Turned out to be the ignition coil.......if anyone was interested...
And yeah it hasn't done any of the above since I changed it, yup you heard...IIII changed it giggle.
I won't go into the whole setting the immobiser off, having lost the fob and having to get an auto electrician to bypass it for me....
