Yes, and a sure symptom of a bad TPS is rough idle. You might also consider that a dirty/clogged air filter, or dirty/fouled spark plugs will also cause excess fuel use.
TPS Star ended in 2012.

Try disconnecting the Throttle Position Sensor (TPS). It is located on the throttle body. A small black sending unit with an electrical connection coming out of the top. On my 1998 Lincoln Continental, disconnecting the TPS brought the idle back to normal. Plugging it back in caused the idle to shoot up high again. It is a sending unit that tells other computers in the vehicle the position of the throttle plates. Other calculations of fuel, air, etc. are apparently made based in part on what this sending unit is saying. I guess unplugging it shuts it up. Of course, it will need to be replaced so that it can again begin sending useful information. Update: I changed the TPS (buy it online if you can wait. Its a bit expensive at Ford). The car ran perfectly after about 30 seconds (so the computer could reset probably). To replace the TPS you will need to take a few parts out. First, remove the air cleaner, disconnecting any vent pipes and electrical connections on it, and get it out of the way. You will then see four bolts on the throttle body (the thing with the two butterfly flaps in it). Unscrew the four bolts and take them out. Then very carefully lift the throttle body off of the gasket. You don't have to take it all the way off. In fact, because it is still connected to the throttle cable and all of the other throttle cable related parts, you can at best tilt it up so that you can get access to the two screws that hold in the TPS. Once you tilt the throttle body up, unscrew the two bolts holding the TPS in and take them out. BE VERY CAREFUL. If you drop one of the screws it could go down the intake. That would be a major problem. However, if you carefully remove the screws and set them aside, the TPS comes right off. Put the new one on, making sure it seats correctly and screw the two screws back in. Then reseat the throttle body and put the four bolts back in. Reinstall the air cleaner and you are done. The whole operation can be done in about 20 minutes. Throttle plate may be sticking
Native starch is not a thermoplastic. It is a semi-crystalline material and, when heated on its own, degrades before reaching the glass transition temperature. WHen starch is heated in the presence of water, glycerol or other plasticizers, the semi-crystalline arrangement present in native starch is disrupted and the result is an amorphous material composed of entangled amylopectin and amylose chains. This material, called thermoplastic starch (TPS) is indeed a thermoplastic since its glass transition temperature is well below the degradation T. Hence starch may be processed in common industrial techniques such as melt extrusion and injection moulding like traditional thermoplastics. Most "starch plastics" found at the market are based on TPS, and many of them consist in blends, that is mixtures, of TPS with another polymer (such as Poly(lactic acid); Poly(caprolactone); Poly (Vinyl alcohol) ; natural rubber...). A famous example of a TPS blend is Mater-Bi by Novamont. Hope this helps. HUGS FOR ALL!
TPS (throttle position Sensor) is a variable potentiometer! Is is connected to the throttle shaft on the throttle body. The ECM/PCM (computer) uses the voltage from the TPS to determine fuel delivery based on the angle of the throttle shaft or valve (driver demand) A loose or broken TPS can cause an unstable idle or intermittent bursts of fuel from the fuel injectors, because the ECM/PCM is fooled into thinking the throttle is moving.

GM. did not start using TPS / THROTTLE POSITION SENSORS until they switch to the fuel injection fuel system. Your truck has a carburetor, TPS was not used on that type of fuel system.
no it will not!
Take your vehicle to your local Auto Zone and have the computer diagnozed for trouble codes - there is no charge. I would venture to guess the Throttle Position Sensor (TPS) is faulty and stuck in the closed throttle position which would cause an over-flow of fuel into the piston cylinders, causing the engine to hesitate and wet the spark plugs with excess fuel. - Good luck.
It is the code for the TPS Throttle position sensor
Check your TPS TPS = throttle position system
P1120 on my 2000 Tundra V8 meant that the TPS was malfunctioning. The TPS can cause a variety of problems. The TPS is located on the passenger side of the Throttle Body.
Could be a bad TPS> (throttle position sensor) clogged fuel filter, amongst about 583 other things--- Good luck
The fuel regulater diaphragm is bad, fix it.
Could be many things. But some things to check/replace might be... -fuel filter -fuel pressure -TPS -IAC
It could, along with dozens of other possibilities.
