ok..this one i can't do on my own..it's not research and it's not building something. my tps needs replaced. i dont' have the money for a new one. they are over 200 dollars. i just simply can't put it with all my other bills right now. does ANYONE have a spare or a used one off a parts tracker they'd be willing to help me out with? i obviously don't expect it to be given to me but in the spirit of Christmas does anyone have one new or used in working condition that they'd be willing to part with cheaply? please let me know  

What engine ?
The 8V engine will run with a bad
TPS.

Why do you think the TPS is bad

Wild

yes it's a 93 8 valve. i think the tps is bad because that's what the diagnosis computer says is bad. plus it wont hold a steady rpm above 1500. it's running like crap. not only that i just replaced the starter and alternator and it still won't crank right. next im going to replace the big wires to power the starter and put in the relay for it if that doens't work. but the tps is bad...it idles fine and runs fine but it bucks really bad when ur going down the road and even if when your not moving but have the rpms and trying to hold a steady rpms *during alternator test at advanced auto* it goes to say 2k. and then from there it keeps dipping down to 1600rpms and bounces around between them. but it's not just at that set rpms. it does it at anything above basically 1500 that u try to hold steady. i can't wheel. i can't drive it. and over half the time the only way to start it is to catch it in gear...if someone can help me please let me know.

Have you checked the TPS adjustment ?
It needs to be in the proper location to
run right.

You will need a Multi-Meter to do this,
you will also need an 8MM wrench or
a 1/4" drive ratchet and 8mm short socket
to loosten the TPS.

start by removing the Neg battery cable.
unplug the 6 wire conector that comes from
the TPS, loosten the 8mm bolts that hold the
TPS to the throttle body and turn the TPS
clockwise, now with the meter set on Ohms
or continuity, hold the probes on the 2 pins
on the right side of the connector, this is with
the locking tab at the top as you are holding it.

Slowly turn the TPS counter clockwise until it
reads open circuit or no Ohms, stop there and
tighten the 8mm screws, you can turn it just a
hair farther it will be fine, but it needs to read
open at idle.

You can check the TPS before you loosten the
8mm screws, it should read open and when you
move the throttle just a little it should change
to an Ohm reading, I don't know what it is, but
it is outlined in the Haynes Suzuki repair book.

I have it in JPG if you need it

ill have to look..but so far im outta luck  

dumb question , what is tps short for,  lol probably something i havant thougth of

   throttle position sensor

You will have to forgive Mark he still lives in the dark ages  - he still has a carb under his hood.....

Hi everyone I'm Nick, MarkyB's wheeling buddy. I have to drive around with him cos he keeps getting stuck

Regards

Nick

Noooo.
i have to rescue him as well. lol
hopefully he will keep 4wd for the day now, instead of ending up with only rear wheel drive.

ok well i called the scrap yard and went to pick up my sensor..turns out they designed it so u cant' just simply remove the sensor. so i bought the whole throttle body assembly + injector. lol not too bad for 50 bucks..now tomorrow im going to get some engine cleaner and a new gasket and wednesday im hoping to put it on. also today i ordered my clicky starter relay kit it'll be here wednesday as well. so im hoping after i put the relay in and my new throttle body she'll be running and starting good. along with the relay im also changing the stock 8ga wires that go to the starter up to 4ga. if that doesn't pull enough power.....grrrr

    are you still planin' on going with the 4.3L \

sometimes, well most of the time, the clicky starter problem lies in the ignition switch itself usually it just gets too dirty along with everything else in the steering column you may want to clean or replace this as well  
changing the guage of wire from the battery is a great idea as well

well the 4.3 would be nice but SO much fabrication would be involved...i'd love to take the engine/tranns off of your hands..but see i don't have a truck..so until i can find one or get enough loot to rent a uhaul i can't get it. maybe after christmas?

thanks for the info , i will stick with my nice carb thanks Nick :-)

tony, Nick it wont be long before it me putting a rope on you two .

Now i will stop invading this thread and leave these guys to it good luck on fixing your TPS
