truck sputters
Hi well I have a 99 ford ranger xlt 4.0 ohv basically it sputters so bad while driving it sounds like a dumptruck but it all started when I changed my o2 sensors but in doing so I broke my heater control valve and when I was going down the road it started sputtering well it started sputtering so I checked the o2 sensors there good and I changed the heater control valve. But nothing so I changed my coil pack spark plugs and wires but still nothing. But on my reader it says cylinders 2,3, and 4 are misfiring and bank 1 and 2 are running lean plus it has a bad aroma of gas in the engine compartment but when it idles its somewhat smooth but when I'm driving it its horrible the sputtering is so bad it takes awhile to get up to speed plus I'm only getting 100 miles to a whole tank that's like 8 or 9 mpg I need to fix this soon. this is my only transportation so if anybody knows what's goin on please I'm all ears thanks

Welcome to FTE swascott1981,
Why did you change the O2 sensors in the first place?
Did you have codes?
Was the truck running poorly?
Do you have a CEL/SES light on now?
Did you check the trouble codes?
When ever replacing any sensor, it is a good idea to disconnect the negative
battery cable before doing any work.
Almost sounds like air metering maybe off or another sensor is failing or
failed.
Check for air leaks or disconnected hoses too.

I think they're asking, specifically, which codes they are - post the numbers...
Also, if you clean the MAF, make sure to use a plastic-safe spray - there are MAF cleaner sprays sold in auto parts stores...
