2003 Ranger 3.0 wont pass smog check (170k).
The only car I have ever owned just failed smog. she failed smog because of too much unburnt fuel in my exhaust. The aceptable amount is 200 and im at 370... Here is a short list of things I want to do this weekend.
Clean distributor cap
Replace air filter
Check and repare vacuum hoses. ( there was a vacuum leak a few years back)
Last year I changes the spark plugs.
Besides this, can anyone think of anything that i can do personally that will help? im not a mechanic but Im not afraid to get my hands dirty. Any information would be a great help.
