car bucking
hey guys
okay so i am new to 5 speed but im pretty good at it now and i can conclude that this problem isnt because of my shifting
okay so when i drive everytime i release the gas pedal or press it down the car bucks/jerks now this is irritating becuase i constantly play with the gas pedal to maintain a constant speed
this only happens sometimes and i THINK its because of cold weather or if the car stalls and is turned back on the problem returns
my friend said its one of the sensors or theres too much gunk (carbon) in the throttle body so if this is the problem, how do i remove and clean all the sensors and the throttle body
also (now this part might not be related to the above problem but its a problem none the less) my car keeps going up and down by like 100-300 RPM on idle and when driving (not when accelerating) and sometimes when i am creeping on 1st the civic just keeps revving (rpm issue also)
the bucking problem didnt return until 2 days ago and its pissing me off so any help is good help lol

The sensor your buddy is talking about is most likely the map sensor. Its right on the throttle body. Little black rectangular thing held by 2 philips screws. This would cause inaccurate air reading. For that matter it could be the o2 which also can cause inaccurate air/fuel mixture.
Both problems could be due to one of those sensors.
Question for you: how is your gas milage?

Lol that's common for civics, and any car for that matter. When you are driving gas is moving around in the tank and on turns depending which way you turn will read less/more.
For the problem, try pulling out the map, clean the sensor up.

let your friend drive your car aswell and see if it does it for them aswell, and if it does not do it for them, then it's your driving. You should be able to get around 500-550 km's to a tank of fuel.

You could have a engine or tranny mount out some where. What it does it, is it making like a clunking sound? Plus i don't see it being any sensors on your engine, because if it was sensors, your engine light would come on and the engine would run like ****, not start to buck as you say.

You do not remove the throttlebody to clean it, there are a few ways of clean it, just get a clean rag, and spay brake cleaner on the rag and then just open up the butterfly on the throttlebody and clean around it. As for the map sensor, it's only 2 screws that hold it on, just remove them and spray the sensor with brake clean.
