How to clean tps sensor

Once opporating temp is fully met, the car idles as tho its dieing and it hesitates when accelerating, when full opp temp is met. when extreme cold temps are the norm the car will run flawless, but if the normal days temp is in the 30's or higher the car idles hard and sounds like its chugging and dieing.

It could be a faulty thermostat. Did it do the same thing before u replaced the t-stat? It sounds like it's sticking closed, then all of a sudden it opens, coolant flows correctly. I'd consider changing it again. Check to make sure parts store is giving u the correct temperature thermostat also. Maybe it's too high for your Ford, delaying the opening.

You may have an air pocket in your system which some times happens.  One way to get rid of it is to take the upper hose off on the engine side,  fill your system with water until it runs out from your engine block, replace the hose, start your car turn you heater on and set to hi keep the radiator cap loose until the temp start to rise then close tight.  Once the air pocket had been remover you can drain some of the water from the radiator using the lower drain plug and add antifreeze.

SOURCE: When the motor is cold and the outside temperature

Are there any service engine soon lights on associated with this problem?

Possible CTS (Coolant Temperature Sensor) or another sensor giving faulty data for the cool air temperature.

Check spark and gas delivery when cool, below 70 deg. If the spark is not being delivered or the fuel injectors are not delivering fuel at this temperature, it will explain why it doesn't run right until it is warmed up.

It sounds like your automatic choke linkage is not working proparly or out of adjustment. It could just be very dirty and oily. You can spray WD40 around the linkages on the carborator and work them back and forth by hand to see if they are moving freely. If they were very stiff at first and then after you sprayed them and moved them around they feel like they work much easier then it was likely just dirty.

Symptoms of a bad tps

old post. but....
a great question, but on a tracker , the TPS , has 2 parts inside
cascaded as one part. so that makes answers harder.
the tests are here.

  1. idle switch bad, means, idle never regulates.
  2. end idle side.
  3. throttle angle side, is complex. (as seen in scan tool)
  4. it detects drivers fast right foot actions and enriches fuel this prevents the hesitation, when you accelerate. if bad it does just that. but does still have full power up hills (after small hesitation) due to the MAF sensor seeing reality and correcting the TPS (errors) see?
  5. the TPS also triggers. cut fuel mode when you decelerate,
  6. and triggers cut off of EGR and .
  7. and triggers , anti snap your next mode , when you decelerate too fast it adds air via the ISC to prevent violent Deceleration.
  8. I told you it was complex the FSM book from Suzuki and GEO both stated all that. on the TPS page.

get the Factory Service manual, real, and see those pages.

Car is hesitating during acceleration

Hi there i have a 2000 v6 camaro and i just rebulit the top end of the motor over the summer my car does this same exact thing ive diagnosed it as a tps but my throttle body is all one piece and i have fly by wire system so its about 500 to replace. when its really cold in the morning it doesnt like to idle smooth also because if my coolant temp. sensor. For you i would recommend doing a compression test on all of the cylinders, checking for spark, and also check and possibly replace tps( throttle position sensor)..

1990 Buick Regal 3.1 has rough idle, hesitates and dies when accelerating.

A lot of new parts! Have a compression test done to gauge the engine's internal condition, and go from there. If compression is good on all 6 cylinders, scan for trouble codes. The compression test may find your problem, something like an exhaust valve burned or not seating properly.

Stalling & Hesitate While Driving

Never attempt cleaning (spray cleaner) a MAF sensor or touch the element, It will damage the sensor. A dirty air filter will put the MAF sensor out of range. The only sensor subject to physical wear is the TPS (throttle position sensor) The low oil sensor will disable the ignition if more than a quart low. The crank sensor triggers the ignition and if not installed correctly will not pick up a signal(.018 air gap) Perform An OBDII scan of stored fault history before going any further to avoid buying more parts you don't need.

I have a 94 Geo Prizm LSI 1.8L. I have a real odd hesitation, sputter. Before the car shut down, it drove fine, except that it you maintained a steady speed the car would sputter - but not when...

Try exchanging the MAP sensor from the other "good running" car. What I think you are experiencing is a flat MAP which fails to read more than the minimum. A MAP sensor out on these cars will make it run absolutely terrible and die as you have indicated.

By unplugging the TPS sensor you are effectively putting the car in "limp" mode. In this mode it ignores a potentially bad TPS, O2, and MAP sensors and or circuits.

Idles up and down...only at low throttle...when I push the accelerator it hesitates, almost stalls...then is ok,...but it has no power...problem seems to be in the low idle thinking TPS...any...

This can be caused by a few things. Yes it can be a bad TPS however this can be caused by a DIRTY TPS. Get a can of throttle body cleaner and clean the heck out of it. The other thing that it could be would be a camshaft position sensor. Once you clean the heck out of the inside of the throttle body with the cleaner while it is running then that should fix the problem.
