why is my 1995 astro van running rich in fuel

Asked by Aug 06, 2013 at 01:07 AM about the 1995 Chevrolet Astro CL Extended RWD

Question type: Maintenance & Repair

1 Answer

9,575

The number one cause of this is dirty/contaminated/malfunctioning oxygen sensors. They get dirty and misread, but there is no code because the unit is working electrically. For most people, I suggest a new one every 60 to 80,000 miles just because they do get dirty, and a bad reading is almost guaranteed to clog your catalytic converter in short order. Also with the price of gas these days, a new O2 sensor can pay for itself in short order. Also, make sure your throttle body is clean.
