It hasn't been running well. Took it into the shop to have tranny fliud changed and asked the guy if he would run a diagnositc on it. All he told me was that it needed a new fuel pump. Got the fuel pump replaced. Still runs crappy. Went to an Autozone and got the codes myself. Here they are:
P0447
P1590
P0171
P0174
P0300
P0305
P1171
P1174
Can anyone advise me on what it might be? Any help would be appriciated.
First, go back and have him reinstall your old fuel pump or get your money back cause he missed that one completely.
How many miles on the truck, when was it last tune including new 8mm plug wires?
You currently have 2 cylinder miss firing, your 3 Amigos are on, your evap vent control circuit is open and you are running to lean.

OK. So I get under the hood and start following wires and hoses thinking there might be something loose. Well, there was. There was a plug unplugged going to the Evap. I plugged it in and it helped. Tomorrow I will trying cleaning the plugs or replacing them, Depending on how they look. Should I just replace them? I've read several post that sometimes it's not so good to change them. Anyway, I got the double platinums so we'll see.
Thanks Disco Mike for the comment about the 8mm wires. I didn't know there was a difference. I am learning as I go. I love my Disco, It is great when it runs well, and if not, it looks real purdy in my driveway. I live in a very small town (about 2,500 people), so I just won't use that mechanic ever again. I'll go 2 towns over and use Autozones OBDII for free. 2003discoII Thank you so much for the codes I will be using them.
You guys are awesome and I am greatful for the help.
