Im been running an sdi v8 in my mk 3 tina for some time and suddenly it started missfireing and wont pull at low revs without missing
Ive been running a (standard coil) thats what it says on the coil, with that supresor type box thing thats for the dizzy, putting the strob on the ht lead it did miss every so often but i cant say ive had this problemin the past.. any ideas anyone

Mismatched or aftermarket rotor or dizzy cap

You do need the right sort of coil for your particular ignition system. I have burned out a few coils in the past before realising that the coils were for a different ignition system. That's the problem with a 'bitsa' setup.

SD1 V-8s all have electronic ignition, and for best results need the correct coil. And there are different types of ignition, depending on age.

ive not changed anything since it was last driven other than plugs and leads. what type of coil should i look for, i know electronic, but what part number or name etc..
im also a bit concerned it may be a bent valve as the throttle stuck last week at full wack!

so i may be looking for a head gasket kit and valve, anyone got such parts.. Thanks for your help guys all the same

You need to identify the type of ignition you have. Earlier types use a ballast system, later not. The full dizzy number would help.

The numbers are as follows
Dizzy is 35DE8 1979
the control modual or what ever it is,is lucas 9BR 47246 A with 49 78 below
Cap is 5402212 lucas
Coil, it doesnt have any markings so imnot sure if its 9 or 12v

I do have anothe dizzy, lucas 54420642. This needs cap etc but it has points and a dwell adjuster by the vacum. Is this whats known as the 2 wire type, others ive seen have a box on the side but this doesnt..

Thanks again
