Check for oil leak(s) underneath the car...this might be messing up your electrical connections. According to my 1984-1994 Tempo/Topaz Repair Manual. It is the Exhaust Gas Recircuation (EGR)valve. A Malfunctioning EGR valve can cause 1 or more of the folloming syptoms: 1) Detonation, 2) rough idle or stalls on deceleration. 3) Hesitation or surge. 4)Abnromally low power at wide open throttle. My 94 Topaz has the same porblem, expect I replaced my EGR valve and it still acts up. So I'm check ing the other parts of that system. The EGR Transducer, and the EGR Vacuum Regulator (EVR). Have your fuel injectors cleaned. About $100 at a garage. When they get hot they gum up because of deposits. Check the distributor, that was the problem with mine, I needed a new one
well if its a carburated engine or has a throttle body it sounds that its throttle linkage has snapped and needs to be replaced. I will assume that the vehicle is carburated and tell you to cxheck the drivers side of the carburetor by taking off the air cleaner and looking at the throttle control on the carb
The throttle position sensor tells the engine control module what you are doing with the throttle as you drive. If you let your foot off of the accelerator pedal the throttle position sensor sends that information to the engine control module and the engine will receive less fuel and it will lose rpm.
It is on because the engine computer has detected a malfunction with the electronic throttle control system.
A Throttle is the fuel control that controls the mixture of fuel and air and the rate of flow into the engine.
It is called a throttle body control module. It is in the engine compartment on the top of the engine.
The throttle body is controlled by the engine computer, which is located on the firewall.
No such part. The computer actuates the throttle plate to control engine speed.
Yes it had a throttle body to control the amount of air getting into the engine.
The throttle position sensor determines the amount of throttle used when the engine is running at various speeds. If the sensor is faulty, it can be replaced by ordering a new part.
on throttle body
Yes it can. The engine is exactly the same except for the throttle body an intake. Just use the ones on the old engine.
The ECM (Electronic control module or Computer) Can and does control Spark advance Fuel injection timing and amount EGR function Engine temperature Throttle position in a throttle by wire system. Monitors engine operation through several sensors Relays information (speed, temperature etc) to the dash display.
Check fuse(s) and wiring. Could also be the control module, an electronic marvel that cannot be repaired only replaced. The throttle link between the gas pedal and the engine could also be broken.
That depends on the year and engine size. On most gas engines it is on the throttle body.That depends on the year and engine size. On most gas engines it is on the throttle body.

Assuming you have a mpfi engine it is in the throttle body.
On the throttle body
On throttle body. It lets in extra air at idle when engine cold and throttle blade is closed.
That light is the failure indicator for the electronic throttle control system. If the light stays on, the engine computer will have stored a trouble code.That is the indicator for a failure in the electronic throttle system.
Throttle Position Sensor (TPS), it detects how open the throttle body plate is to govern how much fuel is delivered to the engine. One of the myriad of inputs your engine control module uses to control your engine. If you are getting a fault code due to the TPS, try cleaning the throttle body out with a spray of throttle body cleaner (not carb cleaner) carbon buildup can cause it to stick. If it does stick open, some vehicles will default to "limp mode" to keep them from accelerating uncontrollably.
Throttle linkage between control handle and carburetor is loose or broken.
The ETC is electronic throttle control. It includes the throttle body, on the intake. The engine computer, under the cowl passenger side, and numerous sensors.
