if my catalytic converter is restricted (enough to reduce my fuel mileage by 20%) should the check engine light be on, or not? (it is not)

Asked by Oct 18, 2016 at 09:56 AM about the 1995 Suzuki Swift 2 Dr STD Hatchback

Question type: Maintenance & Repair

I bought the car with a dead miss, and I am trying to make it run as good as
possible until I can afford to have a engine put in it, I was getting 31 mpg on
premium at first, but the last two tanks have averaged 24 mpg, and it is
running doggier than it was, that is why I suspect the catalytic converter, it
has 138,000 miles on it, the distributor cap contacts (aluminum) were
corroded (I cleaned them up) but, I haven't driven it yet

If the engine has a miss, check the ignition components first.

You may just need a tuneup. Plugs, wires, cap and rotor. Just cleaning burned contacts may not be enough.
