I ordered rubber hoses for idle air control valve. There must be leak there when I checked spraying carb cleaner on them. I also cleaned distributor cap and rotor for now until I get new one. Ill check how strong the spark is tonight. Its getting dark outsie so it will be visible better than on sunny day. I would really like to check compression but have no time I come home late and shops are closed by the time. Also I think gutting out my cat. car has 180kml so Im thinking to gut out my cat would not hurt it

My cat is very loud comparing to my Olds minivan. Mufflers were replaced 6 months ago by previous owner ( I have receipt) so there is a chance of cat being cloged or broken inside not lettign exhaust gasses to pass freely. And of course since I dont know if fuel filer was changed Ill change it as well. It would be nice to diagnose all suspecious components with speacial tools but I cant. Im street type mechanic. I have basic tools and some jack stands and jack. It might sound little but I took off my old 420sel transmission off on the street, rebuilt it down the basement and pt it back, drove the car with no problems for a year then sold it

I loved that car. I had 2 tone interior in it in mint condition but car developed some rust in rear. I dont do body work so I had to sell it. Sorry for long post but if you guys think I should check something elso or I overlooked something that applies to my above stated proiblem please let me know. Thanks
