2001 RWD still getting bad gas mileage
After replacing my fuel spider, plugs, fuel filter, MAF, fan clutch and many other parts, I'm still getting pretty terrible mileage from my 2001 RWD. Not sure what could be causing it. I'm not getting any codes, and the truck seems to run fine. I was able to get 317 miles per tank every time with my old S10. Seemed consistent no matter how I drove. This truck, however, was a mess when I got it. Pretty much everything was trashed. I'm wondering if there's something I missed. Pretty much the only stock part of the fuel system left is the pump, and it tested as holding pressure. Fires the truck up on the first shot every time, so if it's going bad it would surprise me.
What are some other things that could cause bad mileage, without tripping the check engine light?
Don't you hate when that happens?
