Yesterday, I picked up a 2000 Laredo, Quadra-Drive II, 4.7L, 164k miles (43k on a rebuilt motor). VERY clean inside and out. But it has issues. So I got it cheap. It also has a recent water pump and power steering pump. And the tires are good, if poorly-sized (225/75-15).
The major issue are Codes P0300, P0301, P0304, which are cylinder misfires, specifically 1 and 4.
I've already played the coil swap game and it hasn't helped. I've noticed a clacking noise coming from the valve covers. Not loud, but you can hear it very clearly if you do the screwdriver-on-the-cover and put your ear to it. It's louder on the driver's side than the passenger side. But I suppose this could be because it's missing.
I've noticed both valve covers are leaking at the rear, so they're coming off anyway. I've already ordered about $300 in parts from Rock Auto and Amazon... front/rear lubelocker seals, trans fluid, trans filter/seal kit, radiator hoses, a couple coils, a couple fuel injectors, thermostat, and a few other things I don't remember. Oh I also ordered an updated TCM so the 45RFE will become a 545RFE.
Another issue it has is the driver's side power seat doesn't move. It's stuck in the almost all the way back position, so I can't get to the rear bolts to remove the seat. I have a spare power seat track, but without being able to get the seat out, I'm kinda stuck. Anybody have any suggestions on what do about this?
