Car is a 92' Mk3 Cav 1.6L fitted with a pierburg 2E3 carb and MSTSi ignition system.
The problem..... will run fine for a few miles or even quite a while but then.....
Car loses all power.
Makes funky backfire style noises. (except they come from the front of the car)
When trying to idle runs about about 100 or 200rpm (by revcounter) and makes loadsa knock sorta noises and shakes the engine a lot. Sounds like its kinda running on 1 or 2 cylinders or summit but more random than that.
Will then stall and sometimes throw a whole load of smoke out of the Air filter. ( )
Starting is a bitch and will then sometimes vary between running fine and above symptoms.
Soooo.... am in the process of getting new leads and spark plugs (I know this 99% most likely isnt the problem but I needed them anyway so now seems a good time to take them out of the equation).
Also thought.... hmmm maybe fuel filters blocked. Look in Haynes to find location of filter.... check that location and there IS NO FILTER!!!!
So got another in-line filter in shopping list.
Q. do we think it is
a) Electrical / Ignition Related
b) Fuel / Carb Related
c) something else
I just dont want to take the carb apart to find that its actually the electrical system playing up.
