Car sounds like its dragging something...

Hello again to all,

I swear they should make my problem threads a sticky just because I have to post a new one everyday and it would save a lot of time!

Here we go again, today I changed the plugs and wires in my car...the plugs went to some accel plugs from brothers and the wires are FRPP 9mm also from brothers. The install seemed to be a cake walk and only took about an hour, car started and sounded fine so we took off for a little test drive.

As soon as we put it in reverse and got out of the driveway the car got a wicked wicked shake, the whole car was just vibrating like crazy, it was like a giant massage chair. Took it down the road to run it a bit and it just got worse, the car revved up really high several times and the CEL came on and off quite a few times as well. As we continued driving it sounded like there was something dragging on the ground behind the car, a constant rattle tat tat, SUPER annoying, though nothing was actualy dragging. Took it back home and got the OBD I reader (best investment ever) and pulled the following code:

172- Heated O2 sensor indicates lean condition, right side.

Okay so by right side do they intend driver or passenger? After I turned the car off there was a lot of clicking noise (not the usual engine cooling sound) on the passenger side of the car. Is this a simple case of something having come unplugged during the install or does it have something to do with the plugs/wires? I noticed when I pulled the old plugs that they all (except 5) were showing too hot (can take pic if you'd like). I have often smelled fuel when I start my car so I always assumed I was running rich.

I am also having a hell of a time getting the car to idle right, I have done the whole checklist and this is why the cap/rotor/plugs/wires swap of late, seems to have made things worse. Any ideas???

Coolant sensor? Don't think i've replace that and no the car isn't lowered.

The dragging sound is actualy coming from the EXHAUST I think, the strange clicking sound after the engine is off is coming from the back passenger side of the engine compartment, I am certainly not dragging anything.

Didn't try the balance test, how do you do it? I know it was in the manual for the tester but its packed away as i am getting ready to get back to school.

I didn't remove any sensors on the passenger side to change the plugs, however, there was some hose, perhaps fuel line, there that I may have broke lose in my wrenching. I am certain that the plug wires are in the correct positions and the firing order is correct on the dizzy. Hopefully I just pulled something loose.

I also pulled a code 632 (I think) this is just the OD on/off switch thing right? I didn't take the time to cycle that switch. The strange thing is that while on the freeway the tranny wouldn't shift, it revved really super high and the shifts were sloppy and at odd intervals. Didn't think that plugs/wires would do this to my car.

I'll be sure to take more pics in the morning if it would be helpful, I am off to bed now, and up early (7am PDT) thanks for the help guys.

Okay after about 10 seconds I found this:



As you can see there is a small pink plastic hose wrapped in black insulator that goes absolutely nowhere...is this where its supposed to go or if not where does it go? I can't find another end to it so what is my engine missing?

Here's another picture just in case:




And yes, I know I shouldn't have driven it after I heard the first shake I guess I just hoped it would get better.....

Thank you very very much we found that and fixed it, car is running much better now it looks like we broke it during the swap, any idea why ford used such brittle materials here, or is it just because its old?
