Thedriver Posted May 3 Report Share Posted May 3 Hello everyone! These days I removed the throttle and cleaned it with brake spray, because I don't have the special one for the throttle. It was quite dirty and now the car runs completely differently, in a good way. I would like to clean the flow meter too, but I can't find it. Can you tell me where it is and give me a picture? I couldn't find anything on the net that would help me... (engine: 1.4 16v 75hp AUA) Quote Link to comment Share on other sites More sharing options...
Rich Posted May 3 Report Share Posted May 3 You spray it when it's running and it might clean a bit of the inlet manifold, don't take it off as you really don't want vacuum leaks Quote Link to comment Share on other sites More sharing options...
Thedriver Posted May 4 Author Report Share Posted May 4 Ok, but where is it? And one more thing, after I removed the engine cover, I saw some kind of sensor that goes into the rocker cover. I removed it and besides the oil, it also had some sludge on it that I cleaned. What sensor is that? Does it measure the oil pressure or...?

mk2 Posted May 6 Report Share Posted May 6 Fairy liquid mixed with kerosene or diesel. Or to remove Diesel engine oil gunge residue, fairy mixed with cellulose thinners. No other washing up liquid works, only green fairy. I don't know why 🤷🏻♂️ But in both cases, low-medium revs, not a hot engine and a very light drizzle/spray into the air inlet to avoid flooding the engine. Does a nice job cleaning the backs of valves. They changed the formulation of brake and clutch cleaner to stop bad people making "phosgene" out of the stuff...

Thedriver Posted June 7 Author Report Share Posted June 7 (edited) What I did in the video at the beginning, when I was reversing, can you call it a pop? I pressed the clutch when accelerating, with the muffler removed, and the car rumbled a little...
