I replaced mine for second time, first time it was the wrong part (for the SOHC 2.0L SPI), it worked for the most part. This time it was for my engine, 2.0L Zetec-E, and now it revs up to 3-4k RPM and stays for a little bit, then goes down to normal idle. As soon as I put it in drive, or any other gear, it does it again and I can feel the engine trying to move the car even with the brakes fully applied. The ECU has been reset once already. I don’t know what to do. The only things touched were: the air intake to remove it, negative battery cable, and the IAC valve.
Fixed the vacuum leak today. It was indeed where the idle air control valve bolts into the plastic intake manifold on the 2.0 zetec. Instead of going ahead and buying a new manifold and spending the time to swap it, I superglued the metal sleeve that the IAC bolt screws into. It’s more of a permanent fix that what I’ve been doing, but I know it’s still temporary. CEL is gone and hasn’t popped up with 30 miles of driving.
As for suspension, the project is on hold until I can get another new upper strut piston nut for when I assemble the struts I’ll keep everyone updated.
Next: Lighting. The new LED headlights and fog/driving lights are fantastic. Only problem with them is that people seem to think they’re my high beams, so they are aimed as far towards the ground as possible. Still, they’re much safer and stylish than the stock halogen or Sylvania ultras.
Last, but not least: Next phase of the project with be brakes. Replacing everything all the way around, and maybe soon, swapping the rear drums for disks using a Massive Speed Systems rear conversion kit.
