So this morning I replaced my dizzy cap and rotor arm on my 92 cabby hoping it would solve the misfire the car has picked up. When I rev the car it seems struggle and then when I tap the accelerator peddle it then back fires. The car has not long been serviced. Does anyone have any idea what i could do to try and eliminate?

Digifant or Carbed is also another question.
What do Divorces, Great Coffee, and Car Electrics all have in common?
They all start with GOOD Grounds.

I will tell you there was a world of difference in the engine when I put the new NGK.
I had a mis-fire, decided that it was time for a tuneup, got new plugs cap and wires….
Original issue was a bad plug wire….
If I hadn't had a spare car to swap wires and caps over I would still be fussing with it. Cap with one bad wire, new plug set with one bad plug on different wire… new set of plugs when I saw that one didn't have any fire res on the end, Ohmed it and it was open…..So get a new set, but this one had 2 bad plugs and all of a sudden I had 3 skipping cylinders…. Glad my other car showed up. New Set of wires, and NGK plugs as Screw BOSCH and VAROOOOOOOOOOM.
Bosch has gotten a little lacking on QC of parts….Don't trust them for filters, after oil change and flickering light at idle from hades….then the Plug issue……
BOO BOSCH

Sometimes you can see bad ones arcing if you watch under the bonnet in the dark.
Heritage will sort you out.. buy the best you can afford can afford… I've had cheap ones that are bad out of the box.

My car is a daily drive so 10,000 miles a years I've been through a few sets in my time and I've a Mk1 Scirocco which also fitted with Bosch ignition system….
HT leads do need replacing every 3-4 years or 20,000 - 30,000 miles so do get overlooked so if yours are old get a new set.
Your dissy looks dirty, give it a clan between the leads and you can very slight pull up the rubber boot on the HT lead and make sure it’s nice and tight on the dissy/plug then push the boot down to make a nice seal to keep the damp out. Do not pull on the very end of the HT lead or you will pull the metal end off, I’ve done this… and you will need a new lead.
How old is the dissy and rotor arm?

I've never tried more expensive HT leads as very happy with performance of my car and can't really see much benefit as my car seems to keep up with most modern cars (hello Mr BMW driver… )

I changed my dizzy cap a couple of days ago but I can’t seem to find a 10mm rotor arm, the only ones I’ve seen say they are for only 1.1-1.3, does this make any difference? I’m not really clued up on it to be honest I just enjoy driving them haha.

I think I used one like this when I had a Mk2 Golf Gti with the digifant fuel injection system on a PB engine but it was 10 years ago….
Do you have a local euro car parts you can order click and collect (as you get the discount) but not pay online then when you go and collect take in your rotor arm to double check it's correct?

Try a search a local motor factors or if you have a local Bosch stockest ask them?
Beru are also a good make….
Or try and call here as they are very helpful, they have updated there website and not all they sell I'd listed so a email or phone call is probably better.
