So like the title states im having issues with my 98 4x4 3.0. I ran the codes and it came back with p0171 and 0174. Bank 1 and 2 o2 sensors lean rich ect. My mass air flow was junk and i replaced it along with the cam syncro, wires, plugs and fuel filter. It has ran like poop since the first day i got it and all this work has only solved an intermittent no start issue. It acts like it has a misfire, driveable but at times it cant get out of its own way. Today i left work and could not get it to go past 15mph. I pulled over and ran it up in park to 4000rpm a few times and it came back around enough to drive 15 or so miles and had to repeat this process and make it home. Curious if anyone has had a similar problem. Can the coil pack do this? I have assumed coils work or dont. Im lost.... all fluids are good and show no signs of mixing or internal problems. When i did the work to it it ran like brand new and a quarter mile after it was back to the same crap.
Thanks in advance for any help!
