Idle issue

Sonofmayhem · 01-09-2007, 08:22 PM

Ok, my truck will only stay alive with the idle adjusted real high, i dont have a tach so i cant get an exact number. but if we lower it it bogs down and dies. the timing is on, new plugs, compression was 130 all the way across, now could it be the EGR valve? we found some akward wires, does anyone have a wiring diagram or a link to one? thanks

I searched but didnt find anything relevant.

Just a thought. Did you check the TPS? Vacuum leaks? Here is a link to a FSM.

Sonofmayhem · 01-10-2007, 06:49 AM

nope. but how do i do that? i also did use the FSM thanks.

automated11 · 01-10-2007, 06:50 AM

If this is on your truck my 1980 yota pickup did the same thing. All i needed was a new PCV valve and gasket. All fixed

Sonofmayhem · 01-10-2007, 06:58 AM

Na, i sold that one, but i may replace it anyways. its on my 89 4runner 22re, 5spd.

Yotapup · 01-10-2007, 07:26 AM

The FSM has a section that shows you how to adjust. Go To:
Engine
Throttle Body
Tps will be at end of section.
Not saying that is problem but it is a simple check .
The FSM has a good troubleshooting section also.

What do you mean awkward wires? I just finished up a top end refresh on my 22RE, so I have a pretty good picture of what goes where in my head right now.

Someone cut off the plug to some wires on top of the engine so we dont know where to put them. ill find out the colors later, does anyone have a wiring diagram or a link to one? thanks

rdlsz24 · 01-10-2007, 11:39 AM

Check out Figure 23 on this page. Also, if you tell me the colors, I could let you know what they go to since I'm going to be working on my truck tonight.

Sonofmayhem · 01-10-2007, 06:12 PM

red/black stripe
blue/white stripe
yellow/black stripe
They are all single wires and
They are in the same strand of wires as the emmisions

Sonofmayhem · 01-11-2007, 06:38 PM

I believe i read that the red/black stripe, deals with the tps, however the tps plug in is un cut. here is a pic of the cut wires.

What does this sensor do? i think the yellow/blackstripe went to it...

Sonofmayhem · 01-12-2007, 10:37 AM

anyone?

timebandit · 01-12-2007, 05:57 PM

130LBS sounds a little low. Should be ~175 on the 22R. Compession ratio is
10.?:1.

Sonofmayhem · 01-13-2007, 10:14 AM

well the engine was still cold, i am pretty sure it will jump up soon, it was sitting for a while the piston rings werent sitting right so we used some tranny fluid through the spark plug hole to help and they jumped from 120 to 130 and 90-130.

If I can remeber to do so I'll look at a wiring diagram at work on Monday and get with you on those wires. The only diagrams I have available to me right now only go back to '90 and they do not show any wires those colors.
The single yellow/black wire could be to the oil pressure switch and the brown/black wire is likely to be a sensor ground.

Sonofmayhem · 01-13-2007, 05:33 PM

I would really appreciate that.

Did you remember?

Yotapup · 01-15-2007, 06:15 PM

Checked my 94 22re and wire colors do no match with yours. The Temp. sensor you show is a Yellow/Green wire on mine. The other 2 wires look like possibly the A/C VSV. My wires are Black/Red and Solid Blue.
I have schematics on a 89 22re and the wire colors you show do not match.
Hope this helps.

Also checked my 89 P/U and it shows ayellow/green to the temp. sensor. Cannot find the other 2.

Targetnut · 01-15-2007, 06:31 PM

Of course not

I'm going to email myself.

At least there is a better than 50% chance that I will get it at work.

Thanks,

Sounds good TargetNut

I was just wondering about those comp readings. Is the engine a fresh rebuild. Because it may be that your valve timming is off. It only has to be off a little bit and your comp will drop and of course it wont idle very good. I'm not saying thats the problem but its possible. If the engine is in used condition and your comp readings rise when you add oil into the combustion chamber then your rings are not sealing properly.
Also I own a 94' P.U 22RE I will look at my truck and check on those cut wires and let you know what i find

Targetnut · 01-18-2007, 09:53 AM

Looks like the yellow black wire should be for the oil pressure sender. If it has an oil pressure light then you should be able to check and find that the wire has battery voltage on it and if you ground it the oil pressure light should come on. If it has a guage then use a test light and connect to the wire. it should glow slightly and the guage should move to full scale. The oil pressure switch/sender is located on the block near the oil filter.

Now the blue/white wire and brown black wire are supposed to be to the EGR temp sensor. They use this sensor to tell whether or not the EGR is operating. this sensor should be located near the firewall on the EGR valve or plumbing. If this is disconnected I would epect to see a code 71
