Post by: peasey on June 28, 2007, 09:20:51
morning all , so heres todays problem! yesterday i did about an 80 mile round trip with my father in law following me as he didnt know the way.now he drives real slow and obviously i had to adjust my speed to suit,now up to the 50 mile mark the disco behaved realy well with no probs.after that it sarted to run very badly missing on more than one cylininder and coughing and splutering but only while in gear if i slipped her out of drive in to neutral it stopped but as soon as she went in to drive it was there again any ideas?and just to let you all know i replaced the dizzy cap leads and plugs oh and rotor arm 4 thousand miles ago so im scratching my head again

I bought a rotor arm and cap from Halfrauds that managed to fall apart after 50 miles.  Where did yours come from?

Rotor arms seem to be very finicky things;  even if you get one which looks almost identical to the original you can run into problems.  Might not be that but best not to rule it out.

Carbs?

no not at all just starts missing when in gear i have just changed the coil,leads,plugs and dizzy cap and all seems sweet (on the drive anway) and just to let you know its a 3.9 injection.my only worry is that what i have changed is exactly the same nothing is or looks worn dodgyor busted in any way oh well

Had this on my old volvo. New rotor and things went downhill fast a week later. Put the old rotor on and all back to normal. Back to helfrauds and changed for a bosch part and no problems.

I had this too, dizzy cap from Halfrauds.  Only showed up under load becasue they fuel mix is harder to ignite when there's more of it ie throttle open.

Check plugs are clean etc etc.

I found that of the 8 tips inside the dizzy cap only 6 of them were discoloured after I had used the cap for a couple of days, ie 2 of them were not sparking.
