1991 Mustang Throttle Body and Accessories

Throttle Body & Accessories

Under the hood of your fuel-injected 1991 Foxbody Mustang is a part called a “throttle body.” This component has a valve that adjusts the amount of air getting into your engine. Combined with the gas from the injectors, the mix of fuel needs to be perfect to get the most power as well as smoothest operation and fuel economy out of your engine. The throttle body on an older car can cause problems if it starts to wear out, which is why CJ Pony Parts carries complete throttle body kits and various replacement parts. While it doesn’t take much to replace a faulty throttle body, the improvement once the new one is in place is impressive.

1991 Throttle Body & Accessories

Mechanical and Electric 1991 Mustang Throttle Bodies

Different 1991 Mustang engines had different types of throttle bodies. Some were mechanically actuated by a cable attached to the accelerator pedal, while others were electronically controlled depending on the amount of air flow.

In both cases, you want smooth, fluid movement of the valve and a quick response time to make sure your engine revs up and down smoothly and efficiently. Years of use will invariably cause old car throttle bodies to get dirty and unresponsive. They are also prone to leak around the gaskets, where they mate with the engine or exhaust gas recirculation (EGR) valve spacers.

The next time you’re under your hood, take a close look at your throttle body. Do you see any damage or evidence of leaks? How does your engine run at idle and under light and hard acceleration? What about when you let off the gas quickly: Do the RMPs drop quickly or is there a lag?

All of these checks will help you determine if your throttle body needs attention. If the answer is yes, do a search for 1991 Mustang throttle bodies in our online catalog. You’ll find our complete list of throttle bodies, parts and hardware, including color pictures and detailed descriptions. You’ll even find full pricing information.

Rebuild or Replacement?

In some cases, simply removing and cleaning your throttle body will be sufficient. All you will need is a new set of gaskets and some bolts, and you’re off to the races again. You might also want to replace some other parts such as the throttle position sensor or your EGR valve to make sure you’re back in top operating condition. If you have a damaged throttle body, you’ll want to replace your faulty unit with a new one.

With no minimum-order requirement, you can get exactly what you want from CJ Pony Parts and still benefit from fast, free shipping. Get ready for a renewed feel and better power delivery from your 1991 Mustang with a new throttle body!
