O.K......codes....

81
82
84
95
33
63

My car has no smog or EGR equipment. It showed the TPS to be faulty, I swapped it with a Ford part (I have about 10 of them), and that changed a LOT. So, that's where I stand right now.

Code 63 is the TPS all the others are meaningless

HAVE YOU DRIVEN A FORD LATELY!!

Need to redo the base idle now.

Aerocoupe, I was thinking that as well. I'll do it in a little bit. This is what I've been using for the Base Idle Reset. Look good to you?

Tom, Thanks a lot.

The car is still doing a little of the "shuddering" a bit. It does feel a lot stronger though. I am going to get an NOS IAC and TPS and a new fuel pump. Not sure if it's being consistent.

Vinnie do a KOER (engine running) code test as well. KOEO (engine off) is good but the KOER test will give you more valuable information about what the engine is doing when it's running.

I've got plans for that tomorrow right after the base idle reset.

I have it marked, I'll give it a try tomorrow before I do the KOER test.

Just a thought - I thought I had one minor vacuum leak. Only one could be found with spray. I ended up having leaks at the upper-to-lower intake, IAC, EGR gasket, EGR valve, and valve cover. The others didn't appear to exist, but they do/did. I still have two leaks to finish repairing. One is going to require some fill-weld and grinding.

I went through and started carefully sanding every mating surface flat - even my newer Accufab throttle body to IAC wouldn't seal without RTV. New gasket didn't help. The surface looked flat with a "straightedge" (not a mechanic's straightedge), but it wasn't.

I'm up 2 more inches of vacuum since the start of repairs some days ago! The engine is responding much better to changes in variables, and while still a shaky idle with Chuck's mounts, it idles pretty consistently now. I hope to get my tail pipes re-welded and hooked back up soon and move to tuning driving conditions.

I'm curious vinnie - when you are in neutral and quickly floor the pedal, then let off, how quickly does your motor respond? I think that may be a pretty good test to show either vacuum leaks, or a (lack of) tuning issue.

I'll check that and report in today. Stay tuned.....

Anywhere between .6 and 1.1v is within parameters.  The setting it to .999999 stuff is .  The TPS triggers WOT mode at the base voltage PLUS 2.71v.  Every startup  the PCM takes note of the TPS voltage with the throttle closed.  Every time.  Why?  Because it WILL change slightly from one startup to the next. 

I shoot for .85v myself.


catching up........
I don't agree 100%, I do somewhat but.... if your mounting holes are slotted and you rotate the TPS cw and ccw while at idle, you notice the idle will go up and down with it.
I am pretty sure getting it to the value you said is optimum but for some reason I dial it a tad lower to about what tom said.
I noticed that if you put a flat head screwdriver in a tps and image the screw driver is your throttle plate, rotate the TPS, you will see what angle you max out at proportional to the voltage at the green wire.

another thing to look for on a TPS is the max resistance.
I had three identical pn's on a bench , the black and org wire on one of them read 30% lower than the other two.

TPS is fine. These things aren't "adjustable". The EEC will learn where it's at, as long as it is not severely out of range - I believe it will throw a code it that is the case.

As long as it's in range, and its voltage goes up/down smoothly as you move the throttle, the TPS is good and working.

Not sure what Tom is going on about with 0.60V.


they are and in the early days all of them had oval holes.... the TC's escorts and another one I cant remember all 4 bangers have oval mounts.

. I can't get the gauge to the window..

figure out how to with an extender or rig up ,,,,
that's the only way to see early symptoms of fuel pump failure.

you will see the needle go low at high rpm's but you don't want it to go lower than about 25 at top spin rpm,, it the needle should recover very quickly at low rpm's.
my last windshield mount test I did showed my fp at the 17psi range,, put in the supercharge v6 pump for the fix.

For the TPS, my throttle body has an adjuster on the top for it. s far as the fuel pump, Unsure of that. NEXT week I'm going to strip off the intake and re-install it and triple check for vacuum leaks. I couldn't find any visually or with spray, but there may be a hidden leak, so, swapping the gaskets is ten bucks and a little time......weather permitting.
