check throttle plate builds up with carbon
You might own a Daimler-Chrysler product. Consider cleaning (the inside of) the throttle body.
You have an ignition Control Module that you can check that controls ignition timing Throttle Position Sensor that tells the computer where the throttle is so it can regulate and give the correct air fuel ratio.
If you have the 99 -02 Cougar replace the TPS (throttle positioning sensor) on the throttle body.
check the throttle body for carbon build up probably fuel related
DTC P1221 code is: Excessive Difference Between Throttle Position Sensors which means there is something wrong with the electronic throttle positioning sensor system, probably needs replaced
It has to be replaced. no adjustments.
The Throttle Position Sensor is conneceted to the end of the Throttle Shaft inside the Throttle Body. P.S. The Throttle Position Sensor is part of the Throttle Body and must be replaced as a unit. Hope this helps ya.
If your 1994 Jeep Wrangler is stalling and having difficulty starting, there could be an issue with the throttle position sensor. A damaged TPS can also cause hesitation when accelerating.
High idle RPM, stalling, low mpg, poor performance.
The throttle position sensor is actually apart of the throttle plate actuator assembly and must be replaced as a unit.
Check your Idle Air Control Motor located under neath the Throttle Position Sensor.
Give a little more throttle and ease out slowly on the clutch. If that doesn't work you may have a timing issue.
85 THUNDERBIRD KEEPS STALLING. tHE ONLY WAY IT STAYS RUNNING IS WITH A LOT OF HELP. i MUST KEEP FEATHERING THE GAS PEDAL PUMPING IN GAS i HAVE REPLACED THE THROTTLE BODY, FUEL FILTER, DROP THE GAS TANK AND WASHED IT OUT. iDEAS?
The Throttle Position Sensor (TPS) is located in the throttle body a the end of the shaft opposite the throttle cable attachment. Some are permanent / no serviceable. Some can be replaced and with a little ingenuity/skill, even the permanent can be replaced as there are replacements available for all year models.
we had the same problem and replaced all those things and it ended up being the throttle body position sensor.. maybe that is your problem
It's part of the throttle body, entire unit must be replaced.
Sounds like the throttle sensor, throttle body needs to be replaced.
The throttle body on an engine houses the throttle, which controls the amount of fuel that enters the engine. It controls the engine's ability to maintain an idle, prevents stalling, and aids in acceleration. If the throttle body is dirty, it can cause problems with the engine running properly. During a standard service, sludge and carbon buildup out of the throttle body and off the throttle blade. The vehicle's computer is then hooked up to a special machine for an idle relearn procedure.
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.
Would like more info such as the year, make, model, engine and if it is back firing through the throttle body (or carburetor) or the exhaust and at what point does it back fire (accelerating, decelerating, cruising, etc).
If it only happens when you're in gear, maybe your torque converter isn't unlocking and is causing it to stall at a stop.
the throttle cable itself will have to be replaced. the cable is most likely fraying internally.
Try your throttle positioning sensor if not your Ignition Control Module but mostly sounds like your throttle positioning sensor hope this helps ignition controll module was replaced less than 2 yrs ago
1) Check for ignition problem. If you have a distributor, pay special attention to distibutar pickup and also ignition wires. 2) Check the TPS. Voltage should change smoothly as you move the throttle.
