RE: Gas Mileage - 90 Dodge ????
catylitic converters. My truck didn't come with any from the factory since it's a heavy duty (over 8500 gross in 86 didn't require them). They get old, break down, fill up and clog and your exhaust gets all blocked up causing a loss of power. among other things. I'd check O2 sensors first as they too get old and fail, causing incorrect A/F mixtures. You also could have a stuck fuel injector, squirting all the time. How old are the spark plugs, wires, cap and rotor?Air pressure in the tires can also impact fuel economy.

Last year I installed flowmaster exhaust and new cats as well. I have the truck 18 months and never did a tune up. Tire pressure is good. I'm going to check the 02 sensor and buy spark plug and go from there. thanks for the input.
I was wondering about aftermarket gimmicks. Does anything else actually work?
(ie KN Filters, spacers, tornado etc....Just to name a few....)

For mileage? Dunno. Switching from the stock airbox to my 14x4" open element K&N netted me some power since it can actually breathe now. My friend did a carb spacer on his truck and tinkered with it on the dyno and found that it actually did improve power. The rest of that stuff? Give or take. I think people who spend the money for a Tornado actually drive with a lighter foot to see how much better they can get their fuel economy, and that's where the gains come from. I don't believe most of the gimmicks do anything other than psychological.

A garage ask if my check engine light was on. I told him "no". He said sensors are good. I ask the original question in two forums. They both responded with 02 sensor change. It was the best 50 bucks I ever spent. Gas mileage increased 50%.
