Mine doesn't have it and I can't tell what it is with your crappy ***** picture.

 

Hey, all I had was my phone...and I could barely see with the waterfall of sweat running into my eyes....

Its just some big bulb/pill looking thing near the vapor canister. I'll look it up tomorrow and see if I find anything.

 

So, just out of curiosity, I was wondering if there was anything special about the electronic 4x4 dash switch in the 92. I had a brief idea of just connecting the wires to a couple buttons/switches if possible. Getting tired of trying to find this switch....Collector helped me find one but I didn't have a paypal account up in time to get it.

 

I finally got my (awesome) ford OBD 1 code reader in the mail and my replacement 4x4 switch. Now my 4x4 works perfect (yay!) And I was finally able to pull codes for both KOEO and KOER tests. On the KOEO test I got a

121: closed throttle voltage higher/lower than expected
(Would the timing bump and related parts I replaced have anything to do with this)

On the KOER I got, in this order

412: cannot control RPM during KOER high RPM check (no idea)
121
332: insufficient EGR flow detected

Any help is much appreciated.

 

I'd start by testing the TPS.

 

Will do.

....how do I do that...?

 

So I finally went and got a small bottle of whiteout and marked the 10BTC and 16BTC lines on my balancer and did my timing. Man was I way way off. I thought I had put my distributor back on the old mark after trying (and failing) to do it "by ear". So I now have it set to about 14-15BTC.

 

let me know when you figure this out cuz im getting the same thing on mine

 

and what timing light did you get?

 

And the lesson was learned once more.

Two things come to mind on your dismal results w/ Seafoam. Ok...3.
1. Engine must be prewarmed to norm. op. temp. first.
2. Pour as fast as possible w/o completely stalling out & shut off engine immediately.
3. after 20 mins., restart & rev repeatedly, until smoke subsided for the most part, then take it for an aggressive drive.

Which one(s) did you not do?
