urgent help needed
Turbo Mini Forums

ok the mini is 1000cc atm i just bought new
electronic dizy
coil <bosh gt40 non resisted> checked wire has 12 volt
leads
plugs ngk bp5ey

put it all in and ran great turned it off packed up went to start it again and it runs off couple cylinders
when reving the motor when it gets in the high rpm somtimes it kicks in and runs great till it reaches idel again when u check for spark on 2 n3 none while running

im going to try it when it is cold to see if its only when hot but does anyone have any idea on whats going on its driving me totally nuts

on my 998 mini I use BPR6ES spark plugs, different to yours? Just something I noticed?

cheers ill try anything just tryed 3 times when cold work brilant soon as it get warme drive up street n back cuts out cylinders more ideas could it be electroni dizy faulty

tryed set bp6ey v groved style still stops when warm
could it be the gt40 coil non resisted heating dizy up stopping it from sending spark to all cyl

You may have a balasted supply to the coil which if memory serves uses 12volts to start the car for extra boost be reverts to an 8v supply once running. This will not supply enough power to a 12v coil once running. * I MAY BE COMPLETLY WRONG AS IT DEPENDS ON WHAT SYSTEM YOUR CAR WAS RUNNING!!!!!!!!!!

Do a process of elimination. Fit the old coil with the new dizzy and try it, then if the problem is still there try the old dizzy with the new coil and try it to see what is wrong.
Im thinking its the wrong type coil

I seriously doubt it!

thank u for ur help ill do the process of illimination againg to day

for the comment of 12v the goes to 8 volt i have tried straight 12 volt from battey no diffrent

When you say plugs 2 and 3 aren't sparking after its been running. What colour are they when you take them out? It could be that the its running a little rich (possibly choke seals) and those 2 plugs are fouling up?

1/4mile in 13.2sec @ 111 terminal on 15psi

Are 2 and 3 definately not sparking? or are they just misfiring?
