First clean throttle body if problem persists re-adjust TPS if problem still there then replace TPS but pull the ECU codes first to verify that code 11 is present telling you the TPS is bad.

To clean the throttle body remove the air intake hose and examine the intake and throttle body for excessive carbon build if found then buy a can of throttle body cleaner labeled "safe on oxygen sensors,TPS's and catalytic converters" and make sure your engine is fully warmed up prior to using as when the throttle body is hot it dissolves the carbon easily and quickly.The labels usually specify to park the vehicle at groung level (0 degrees,no inclination) and have the engine running but I disagree I instead park the vehicle on a hill facing down and shut the engine off and hold a rag below the lip of the throttle body and poor the stuff and use a tooth brush.

Normally you can re-adjust the TPS:

and not replace it but re-check you timing after you change it as it can retard your engine timing my as much as 10 degrees and cause your engine to overheat.This is the part # for the 85-87 22R-E:

TPS Toyota # 89452-20060
TPS Toyota # 89452-20060

The part # stamped on my 85 4-Runner is Toyota # 89452-28010/30,ND # 198500-0100

At least one day before re-adjusting or replacing TPS spray both Philips screws with a deep penetrating lube several times:

1)PB Blaster
2)Liquid Wrench
3)Kroil Oil
4)Aero Kroil & Sili Kroil
5)Toyota Rust Penetrant or High Performance Penetrating lube
6)Rust Check

Any Public Library in your area would have the Factory service manual,Haynes,Chiltons,Mitchells,Bentley and Toyota repair books.

1)buy a used one off e-bay
2)some Toyota dealerships may give you one or sell it for $10-20 (used) as most Toyota dealerships don't repair many old Toyotas and no longer need the service manual
3)some public libraries sell their old books as they are not in demand any longer
4)some free buy & sell classified papers,websites and bulletin boards may have some used ones for sale
5)some junk yards may have one laying around
6)some Toyota specialty garages may have one laying around and no longer use it as the vehicle may be too old and those mechanics probably have so much experience that they could publish their own factory service manual with corrections and "real world repair tips"
7)if someone has the FSM maybe they could scan all of the pages and post it on a site for all of us to download or view.

tps not closed at idle

Hey bud, your tps isn't closed at idle so your timing is gonna be off by 20 degrees. The tps closed and the data plug shorted, set your timing and then pull the jumper wire and affirm that the timing advances and your set. Just went through this with mine. Tim

 

Thanks for the help, but one thing where is the plug i have to short???? i've looked everywhere but i not 100% sure which one it is. in the cheap chilton book it doesn't tell the location. Someone was telling me with the plug NOT shorted that it should be at 10-14 degrees. When i put it at 14 it is a complete dog up hills. So i have it at about 20 degrees and it doesn't ping or knock up hills. I'm doing a chain and waterpump this week due to a little chain slap. i was thinking maybe the chain is stretched out so it is messing with the timing. Could that be true?? thanks

 

DCL location

The Data Connection Link is located on the passenger side of the engine compartment and is up by the top of the inner fender. It has a multi connector pin (black) with a flip cap on it. In your chilton manual will be a picture of the two pins to jump. I use a paper clip and you will know when you have a good connection when with the key on,(not starting) the check engine light will start flashing codes at you,not to worry tho. This modes takes the advance out of idle and allows you to time at 5 degrees, as it is idling after setting idle, pull clip and notice the advance kick in. Buy the steel guides when you do the chain, chances are the sprockets are good and the tensioner as well. Don't worry about the pieces in the pan, the oil pickup screen is huge and parts will not block it shut. The chain streatch if any will not cause the loss of power you have. If you jump the dcl and check timing and pull the clip and see no change at all, the tps is not closing all the way at idle. 20 degrees retarded. All the sprays and additives and cleaners in the world are not gonna solve this, believe me. By the way, if when the codes are flashing, if it not the normal all clear system flashes, read them and look in chiltons for the reason. By disconnecting the battery for a couple of minutes, it will clear all codes. Tim

 

I looked for the test connector and i cannot find it on the inner pass. side fender. All there is; starter relay, and another box with three wires coming out, and a couple of yellow connectors. No black connectors with multi-pins. I wanted to check to see if the tps was working but i can't find this stupid test plug. what a drag. thanks for helping me out.

86 4runner 22re EFI

 

If I am not mistaken, on an '86 4runner the test connector to set timing is the same connector to pull engine codes. May be different on a '92, but I have a '86 4runner and it is on the drivers side fender. My book labels them as the "T" & "E1" pins to short. Give that a try and let us know.

 

don't see it

I swear i'm not blind but i don't see it on the driver or passenger side inner fenders. It seems to look like a square plug from the picture in the book. There is no square plug.. I see onle one black plug behind the airbox with 4 wires coming out of each side it is round. I have been looking for a multi-pin square plug. This is really driving me crazy

 

Just in case you still need test conn info

On my '85 22re the test conn is on middle of driver side inner fender it is two female plugs housed in a yellowish plastic plug that fits in a black rubber holder. when you short it with engine on the ckeng lite should come on/blink. careful not to let the short wire touch any metal parts. Pete
