I've done the TPS adjustment 101 and im having problems adjusting it.

When I have the TPS pluged in and with the key in the ON position I have to have the ground wire in the top plug and the red on the right plug or it wont come up with any reading at all.

When the reading is going through I hear a click comming from something and the signal always comes out to a negative number.
I have a DMM and I set it to 2k and everyone says to set up the tps to 1K.. My TPS can only be adjusted between .777 and .700.
Am I doing something wrong or is the TPS screwed up?
I'm adjusting it because my car boggs when going uphill when im below 2k-rpms.
and I only get around 370kilometers to a tank of gas.

I've read you guys get close to 350 miles!

Are you sure you don't have the meter set to AC voltage? that .7 number is awful close to the "rms" number of AC voltage (for example, your house voltage is actually about 170 PEAK (top of sine wave) volts, but only 120 is actually "working" for you- it's .7 or so of the peak voltage, both pos and neg portions of the wave)...anyway, getting off the subject here...try this- instead of trying to read resistance, put the meter to DC volts, on the 3 volt scale if it has one...put the black (neg) lead on a good ground (I use one of the throttle body studs), with an alligator clip if possible (frees up your hands)...then (with TPS plug connected), put the red (pos) lead on the green/red (I don't have the schematics with me right now, somebody correct me if the color is wrong!) wire coming from the TPS...warm the engine up to the 750 rpm idle speed, and look for 1 volt or so (.9 to 1.1 is fine)...BTW, I think all of our cars bog going uphill in the "low torque zone"- it's normal

i just tightened the TPS screw as tight as it could go and the car wont idle very well now. BUT it seems to have a little more "up hill" torque.
off hand does anybody recall if weither or not the screw should be turned in or out for the voltage to go up?

87RX7TII

Um, I dont think so... the guage has the OHM symbol next to it and it says 2K. I actually tried it on 200ohms but it wouldnt give a reading at all either.
up in the left corner it has a setting for ACV so I dont THINK I messed it up, but maybe.

I will go try the DC volts one you've suggested and i'll see what it comes up with.
When you say "warm up the engine to 750 rpm speed how do you go about doing that with the IC off or are you talking about a N/A?

also, I know im afraid to push my car into spooling going uphill but it also slightly effects the forward pull of the car. How high do you have to rev inorder to spin your tires? I just tried to see and I couldnt get it to happen, even at 4k rpms. It would just jump forward and bog down.

if you want to keep it on resistance, open the back of the meter and check the fuse- you probably blew at some point, that's why the resistance scales don't work...adjustments using the voltage are slightly easier for the novice, though, not as "twitchy"...downshift when you're going uphill- does it still bog?

RETed

TPS does not affect WOT power unless your TPS is full screwed.
What is the resistance reading with the throttle all the way open???

Resistance is resistance - the ohm (Ω) symbol is resistance.
DCV or ACV doesn't matter.

when i've downshifted it dosent bog but it does definately lose power.. I cant keep up speed with anybody, even transport trucks

The TPS with WOT is .777 no matter what way i turn the TPS it wont go above .777 or below .706

87RX7TII

well I cant seem to get a voltage check of a AAA battery so the DMM must be FCUKed
Im trying to take it apart now

WAYNE88N/A

if you're reading the meter right, then the tps is screwed- the wiper is stuck on the .7K ohms spot- have you checked the fuel filters?

87RX7TII

I dont have a wiper its a digital meter

WAYNE88N/A

no, the wiper in the TPS (the "pickup" that runs up & down the coil resister when the TPS plunger moves in & out)...O.K., let's start all over- does the meter read around zero ohms when you touch the two probes together? if it does, then the meter fuse is good, and the meter should be working properly

87RX7TII

well i cant get the DMM opened the full way and I dont want to snap the bottom off. I've tried testing the voltage across the batt and its comming up at nothing, same with any 1.5v battery I check. it checks resistance but not voltage.

I just pulled the trailing plugs for the front and the rear rotor, what I was expecting to see, was what I got.
The back plug was a dark tan/brown color and was dry while the front plug was clean as if it came out of the box and was wet. The front rotor must be getting too much fuel.
If i go out and buy performance coils do you think it will help with the fuel in the front chamber?

WAYNE88N/A

I wouldn't think so- sounds like the injectors need a cleaning...I think you blew your meter fuse, too...

87RX7TII

i just cleaned the injectors, and yep im sure I did!
i need to find out why its flooding the front

87RX7TII

when I took it to the dealer about 3 months ago he said it wasnt building complete compression on the front rotor because a bolt was missing. He also said Im going to need all new gaskets for the upper manifold, since the bolt was left out. After I put the bolt on, I went against what he said and left the "new" gaskets in there" IF I go by with a can of starter fluid and I start spraying around there should I be able to find a leak if there is one?

I'm still having problems with my TPS adjustment.
I picked up a new meter and I STILL cant get resistance.
I'm going to do even more searching on the TPS adjustment just to make sure im doing it right...

I'll actually write the steps ive taken..

Pulled the TPS (white connector) Off
Set my Multimeter to 2K resistance.
Inserted the POS side onto the top prong (green/with/orange stripe) and grounded the other prong...
They say im suppposed to connect it to the pins on the orange and green wires .. They are the two opposite top connectors right?

HAILERS

The colors on the engine harness side of that connector are different from the wires on the tps side of that connector. I thik thats one of the reasons you are ...confused.

The Green wire with a Red stripe.....on the engine harness side is one of the wires your interested in.. in a sense.....it connects to a wire on the tps side of the connector when the plug is coupled. THAT wire on the tps side is one of the wires your working with.

Then there is the second wire.....oh, by the way, is this a series four or series five. And does the voltage part of your meter work now?????? Can you see 12v when the meter is put across the battery terminals????????????

What happens with your meter when you put it on ohms and then touch both the probes to each other???

Can you take a picute of that meter??? And post it. Does it have a name??? RadioShack?? WallyWorld?? Or??????

87RX7TII

its a series 4
yes I went out and purchased a new meter which works. re tested the tps and I must still be getting it messed up
I've tested each plug and prong and nothing comes close to the resistance its supposed to have

87RX7TII

It wont let me upload the picture...
its made made my Equus...
I'm sure the meter is working right because I just purchased it and all of my preliminary tests have worked..
I just need to know what wires to connect to...

"it connects to a wire on the tps side of the connector when the plug is coupled. THAT wire on the tps side is one of the wires your working with.

"Then there is the second wire....."

which wire is this??
