I have just replaced my HT leads, dizzy cap, plugs and rotor arm, and this has not cleared my problem.
My car starts great then after about a secound runs like sh!t for 3 or 4 seconds and then brilliantly, but I believe I have a leaking valve or injector, my golf is an 86 GTi, with the K-jet engine, I would expect the injectors or valves to be worn, as the poor old pensioner has 192K on the clock now. I might retire it at 200K.
It could be the timing as my car does pink a hell of a lot, running on un-leaded, but it does not run any better on LRP.
Regards.
Dean.
