Thanks Pete. So I am basically looking at a possible myriad of things. Why can't ever be a single shot......I have plans for an ACCEL DFI in the future, then it's bye-bye to EEC mazes. Thanks for all the help guys, will keep all posted....

Is it a ford pcv valve, and the correct one? When I bought the 88 3 years ago I did all the T/C usuals, fpr,tps,module/stator,O2S, plugs,wires,air,fuel,still kept getting a code 42 after idling longer than 5 mins. I then realized that because of my big hands and the location of the pcv valve, I had never changed it, I had the new one in the console, put the new one in and wala,the idle went up 200 rpms(had to reset that)and no more check engine light. Fords are very critical with pcv valves, especially our cars. Look how a T/C runs if you pull out the dipstickout while they are running, they almost stall.

**Update** Okay gents, this morning, about 10 minutes ago, I went ouside to warm the car up and do some troubleshooting. When I started the car, it fired up, but with what felt like a bad miss, felt like 1-2 cylinders weren't firing. I revved the motor up to keep it running, up to about 2-2500RPM, and the miss was still present, after about a minute or two, the miss just dissapeared. The CEL came on during the course of it, so I pulled all the codes, only thing I got was the damn 42 again. That was KOER, KOEO, and the CM tests. The 42 was in the CM. I cleared the codes, started it up, and this time no miss. Drove it, got the CEL again, came back, pulled codes: 42. Is this related? It was first time the car started like that since I've owned it (5+ years). The car has brand new everything almost, TFI, cap, rotor, plug, wires (all motorcraft), Fuel pump, filter, 02 Sensor. I don't think it is spark, I am thinking I may have one or more borderline injectors at this point. I am going to run the fuel diagnostics again, but the two times I did before I saw nothing that would point to a bad injector...any ideas guys?

The fuel system diagnostics aren't going to find a non-firing or intermittent firing injector. The diagnostics could help fnd a leaking injector.

The fact that the code 42 is coming back, as a CM means that under some condition you are running rich for (at least) 15 seconds in closed loop,- feedback mode. The fact that your not seeing it as a KOER code says something but 'm not sure what.

I think I'd run that test on the ECT first and then the VAM. Let us know what you find.
Also the TPS test (not just the base setting, but checking for flat spots and drop outs) does no always find bad ones.

Pete,
I checked for flat spots in the TPS test, and came up with none. I am going to try again with the KOER test, I am not believing it, there should be a code. The CEL comes on ONLY when I am off the throttle. I am going to go out and test the ECT, and VAM today, as well as fix the window track, and some other odds and ends. The stuff you sent me was great, but I have one question, which wire to probe on the VAM tests?

Did you check the hose to the FPR for gasoline or the strong smell of gas?

**PLEASE READ BEFORE VIEWING PIC***
Pete,
Nothing doing with the vacuum line, just a very faint smell of gas.

Ok, testing!
Per Pete's awesome page, VAM checks out to specs.
Once again, thanks Pete, can't explain how much help you have been so far, the ECT checks out according to the pic you sent.

So, removed the intercooler, IAC, and blasted the hell out of the TB and IAC, figured I should check the ground on the compressor housing and.....see pic....

It was like that when I looked, not even attached. So my question is...........WTF?!!?!?!? Why would the CEL be intermitent if the 02 sensor had no ground? Why just a code 42? Bleh, gonna go grab a connector and re-do the ground, and if it don't fix it, I am driving it off a cliff into the Chesapeke, see how rich the thing runs then!!

Update:
Pulled the plugs, all four, each one was caked with carbon. At least now I know each cylinder is getting extra fuel. Regrrounded the one at the compressor housing, put everything back together, started it up. Seemed to idle slightly better. Figured I would take it for a drive to try to clean off the plugs. I drive it about fifteen feet and BANG! On comes the CEL. Same damn thing, 42. SO I drive the car anyway, couple WOT runs, and some cruising. Car still feels 70%. Get back and park the car, letting it idle awhile, I get out, and a bunch of smoke is coming out from the bottom of the car. Not oil or gas, like something is burning. I pop the hood, seems to be coming from behind the head. I didn't do anything back there. So I let it cool, kind of hoping it catches fire and explodes. I am guessing I have to un-do everything again, to try and find what is burning, or leaking. Even though I was not anywhere near the smoke seems to be coming from. So I am taking a break for now.....

Just cleared codes and ran car again. Now get a code 65 (vaf below test min.) and the 42. Guessing it is related. For the 65, is there anyway to correct? Or VAM must be replaced?

I'm wondering how you got codes out of it with the 02 ground broken. I've always heard the EEC won't report codes is that wire isn't grounded????

Was the 65 a CM code? Erase it and see if it comes back.

Do you ever get a code 34? Has your car had the emmissions recall performed. If you got a black/green plastic delay valve in the vacuum line at the EGR valve, you had the recall.

You could try what Steve X82 suggest here: http://natomessageboard.com/Forum1/HTML/012164.html
Run the voltmeter into the car and drive around. See when the 02 doesn't switch.
