Hi Rob. . .

If you can get a visual on the switchs, the reverse one is located near where the shifter goes into the trans I think. The other one I don't recall right now, but I guess I'm trying to find out if you have more than two. Something is signalling something to the ECU when you come out of neutral.

I tried to find you a picture of the Idle air control / idle speed adjustment, but have not yet.

If you can post some medium / low resolution pictures of your various underhood components, it might help.

Most of the USA trucks are carbed, so I need to see pictures to indicate adjustment points.

added note:

I just noticed something twilight zoney about this specific post:

It's number 626.

MazdaBsynchronized with a transmission question.

i can't see any any switches on the trans. even snapped some pics and other than the shifter linkage, didn't see anything else.

here's what I was able to find in regards to the IAC with my 'mitchell's on demand'

connect jumper wire between ground and green 1-pin test connector in right rear corner of engine compartment. connect tachometer to negative side of ignition coil primary circuit (white wire). if idle speed is not within spec rotate idle air adjusting screw on throttle body.

idle speed for M/T is 750 in neutral. there's no spec for in gear at idle.

so, that means in neutral my idle speed is where it should be.

i'm leaning towards these switches you're mentioning... but, like i said .. i can't find one.. LOL

thanks

Alldata says basically the same thing. . .

PREPARATION

Check engine condition (spark plugs, vacuum hoses, etc.)
Make sure all accessories are "OFF."
Warm engine to normal operating temperature.
Connect tachometer to engine.
ADJUSTMENT

Ground test connector with jumper wire.
Test Connector

Check idle speed for these specifications: 750

ok. . .

back from some research. . .

both the neutral switch and reverse switch are located on the extension housing. . .

You aren't going to see either of them unless you get under the truck. . .

one switch has bullet connectors. . .two wires. . .with the key ON, engine OFF, with the shifter in reverse, reverse lights should be ON. . . unplug one bullet cnx. . . reverse lights should now be off. . . plug wire back in. . .reverse lights should now be on. . . that is your reverse switch, ok?

The other switch is the NEUTRAL switcfh. . .it has two wires. . .with BOX connectors. . .in neutral. . .continuity either exists, or it does not. . .that is the state you must have to keep the idle circuit stable.

This is just a temporary / semi-permanent work=a=round until other things can be verified.

If you cannot find the switches by actually climbing under the truck, the harness enters the transmission tunnel via a wire bundle which comes down the passenger side of the engine. . .you can follow that harness to where it terminates at the switches.

There is an offhand chance that you got a vehicle that has had the automatic swapped out for a manual. If that is the case, there is going to be some work required to verify correct wiring.

Because you own an OBD 1 system. . .your check engine light will not necessarily illuminate to tell you of a hard failure, but the codes (if any) can be retrieved by grounding out the test (green) connector. That is something that might be worth investigating. . .I don't have the link, but it is a recent post on the board.

here's the link. . .this probably needs to be stuck somehow. . .to keep it from disappearing into the inky black darkness. . .

Here it is, Thursday night.

And once again the response team has been put on internet hold.

Maybe it's just me.

But this kind of thing is getting old.

I don't get closure to these threads when they fray out without specific resolution.

To me, it's like running out of toilet paper and there you are. . . stranded.

Added edit. . .appropriate thread title. . . weird PROBLEM and

sorry tweaker... I've been busy with 2 of my other 4 vehicles, family, work & home chores, among other things. I haven't had a chance to get under it and investigate any further as yet. I've been driving one of my other vehicles the last few days.

perhaps you shouldn't take it so personally. hit 'subscribe to this thread' and you'll get an email when I get a chance to pursue further. just like I got an email notifying that you posted your response. I'm sure you have other things to do also than sit around clicking refresh 75 times

thanks again for your help..
