So basically, I want my car to be in good shape for the upcoming winter. I currently have a rough idle, especially on startup. The car wants to die and is pretty rough. Sometimes the check engine light (CEL
) blinks, sometimes it's steady. The code that was pulled was for a cylinder #3 misfire. Bummer.
In any event, it sounds like a good opportunity to get things fixed up on the top end! The car just rolled over 200,000 miles, and there are things that could use an upgrade. For example, after 200k, my cooling system gave out, and the plastic Y-pipe near the battery that the coolent flows through basically crumbled away. Had to replace it. I think this had something to do with my water pump failing as well. Either way, the car has a new water pump, a new Y-pipe from NAPA, and the coolant was flushed/replaced.
Onto the misfire...
As there's no way I'm getting my arms back there to do the work on the back 3 cylinders, I'm planning to yank the upper intake manifold (UIM
) and go to town. Here's what I have planned so far:
Replace all 6 spark plugs: NGK Laser Iridium (6044; #ITR5F13)
Replace back 3 coil-on-plugs (COP
): Delphi (GN10192)
Replace all 6 UIM
seals/gaskets: DNJ (IG4192)
Replace Positive Crankcase Ventilation (PCV
) Valve: Motorcraft (EV-243)
Hose: Motorcraft (KCV-117)
Valve Gasket: Part#???
I want the top end to be good for another 100k miles, or until the car is junked. I want to do all 3 coils in the back so I don't have to do it again, I can do the fronts as the need arises in the future.
Will someone verify the part numbers are correct, and offer any other suggestions of things to check whilst I have her tore apart in the near future?
Oh! Will you guys suggest a good scanning tool for a driveway mechanic like myself? Budget: Less than $200. Must be able to work for my 2000 Taurus and my 1995 Eclipse.
