if you put tps in the search engine it will give you links on how to set it correctly with the entire procedure including the timing. i dont know the link off hand but just type it in the search engine on this website.

I.was kinda looking for some personal advice I have the link but I did not understand all of it

I think I may have had a little better luck than I did last year

I was actually testing the wrong two terminals.
From the was I.was looking at the picture I got.a little confused.

I will drive it a couple of days and see

Go slow and take some time to do it. I used alligator clip leads on my DMM to clip onto the pins of the tps. It makes it a lot easier when you have to get the feeler gauge in. I also got very confused with the orientation of the connector and which pin was which. Once you get it right the engine will thank you. good luck

Truckk is allot better but as I push in the clutch and let off the gas pedal I hear it motor act like it wants to stall.
It will.do this about three times then level out and idle normal
It will do this all the time
It will idle then drop real fast then drop
Kinda like if you are reving it up

Does anyone have any ideas

does anyone have any idea as to why my truck is reving up by itself?
i have no codes. thanks

I think at 350k .. you might look at shaft play .. this will easly change "readings" ..
believe me , might be time to replace !!

What kind and whers? Are you talking about the distributor? I am still using the same one

40vern

I reset the t p s and checked the shaft on the destributor. Everything checks good but I still have someone reving up the motor for me

Team420

I believe he was referring to the shaft inside the throttle body that the butterfly is attached to. That shaft is what the t.p.s reads position of, and if there is excess play, you will never get it set correctly.

How can k fix.this. what parts do I need?

40vern

Went to the junk yard and I ended up getting the plug for the t.p.s. for free. I figure I can set the t p s easier with an extra plug.
The throttle body looked to bad to buy.
I was going to.get the shaft out of it

If you have an automatic transmission, the easiest way to check the TPS (BY FAR!) is by using the diagnostic port. http://www.ncttora.com/fsm/1990-1995...1/troubles.pdf (page AT1-36)

Thanks. I have the old manual.
If stoped reaving up by itself. No codes
Now I have a little stuffed every now and then
If I rev it up by hand and it idle back down I hear a very little sucking noise.

I am slowly replacing vacuum lines

Set timing today. I still have a slite miss when I hold it at a high r.p.m.
Wonder what this could be?

40vern

well several years later i am trying to reset the tps.

i an get all three measurements on my meter except for test number three where you check you tps using the .57. i am at a point where i am giving up on this.

If your trying to get rid of the little flutter or miss. I seriously doubt the TPS has anything to do with that... valve's. Or Injector would be more suspect to me...

40vern

i am sorry for the miss information. step 2 was to use a .57mm gauge and i should get the a reading of 2.3k

i never could get this but i could it to read correctly on the other three test.

the full throttle i was getting open loop till i moved my meter to a different setting
