rich

Hello everyone, I'm a long time forum lurker and have had a 2nd or 3rd gen Explorer in my life for the past 10 years. I currently have a 2006 4.0 V6. She threw p0172 and p0175 codes a week and half ago. I was like cool no big deal, maybe I gotta do some refresh stuff. I went ahead and replaced...

So I've got a 97 5.0 with constant negative long term fuel trims. I also only get 7-9mpg(city only) with 3.73 and 32s. It should be much better than that... Bank 1 likes to stay around -15 to -20 and bank 2 around -5 in park/idle. Plus or minus some for AC on/off or in drive. While driving they...

I have Bank #1 - Rich and Bank #2 - Lean Codes! ???? P0300, P0301, P0302, P0303, P0316 Codes were corrected by replacing the plug wires and cleaning/gapping the plugs. I have new plugs on hand and will replace them. I used to think I was fairly savvy at diagnosis, but those days are gone...

ok so i have a pretty much bone stock 4.0 in my 93 x. on my most recent trip to firestone the manager took it for a test drive for final inspection. and he told me that the plugs were pretty black for only being 2 years old and that my fuel mixture was pretty rich. i know him on a personal...

Hi, I have a 99 Ranger 4x4 4.0L. The truck is currently running rich, with the following codes P0172 and P0175. A little history on the truck, it has around 138,000 miles, a new water pump, new injectors and a new rebuilt MAF sensor from VIP. I have pressure tested the coolant and fuel...
