Every other oil change I run a bottle of liqui molly diesel purge when I replace the fuel filter. Most reliable car I've ever had.
I poured in the whole bottle when changing fuel filters recently, and the engine seemed to run quieter with better fuel efficiency right afterward.
Fuel filter would be my initial guess. Or maybe your air filter is so filthy that engine cannot suck air through it. So, check air filter first (filthy/not filthy) and if it is not that filthy, proceed with fuel filter.
New stuff i attended to. checked cleaned and pull apart the Warm up regulator. Was not clogged or dirty. worked fine. replaced the fuel filter, which i did notice was a little crummy. but normal.
Recently I did a tune up on the car, which consisted of a Amsoil/Mann Fuel Filter. However, I was still experiencing it on occasions before the tune up was made.
ok so replaced the fuel filter, the fuel that came out the "dirty" side of the filter was black and had small particles in it
So I changed the fuel filter carefully and was disappointed that it didn't seem to improve.
On my mk3 I ran a fuel cell gravity feeding a bosch 044 pump with -6hose. I chose a K&N fuel filter that had a billet aluminum body with a screen disk as the filter. K&N verified this was OK for fuel injection. Well, the pump was so high flow that the screen filter was a real restriction and bent the screen kind of forcing it half way through the hole.
