Hello all, have a Volvo 440 K Built 94 1.8 l (90hp)… For a week the engine spins around… so when I’m idle… the engine is very restless and turns between 1500 – 2000 up and down… so whether you give gas and would take away again… 1. Consumption increases 2. Suizit danger ( that neeeervt really people think already what a nut and gives gas… which I think I want to run..real embarrassing) has got a couple of forums already through… One says throttle cap dirty, one says air mass meters and others again light masks… How can I find out what it really is? and how do I clean the throttle flap, if I just don’t fully expand there but just say pure with cleaning gasoline or brake cleaner or what stuff??? Please help… unfortunately don’t have enough coal for workshop otherwise I wouldn’t be annoying ;-(
