Accelator pedals sticks on hot days,during cold days is ok.Cable is ok and lubricated ,so could be carbon deposit in trottle.
Just wondering if i can get instructions how to clean trottle body ,but safe way ,and i read in other threads that could be idle speed issue after clean up .why ?
does not ecu reteach itself ,same like after cleaning map sensor two platinum wires i did not have any problems afte r cleaning was done ECU was just fine and engine was running smooth.

Its not that difficult to do. Chances are if your throttle is sticking its just carbon buildup in the throttle body. I have never heard of a sensor going out before but im sure it can happen. You do not need to take off the throttle body to clean it and fix this problem, but then again every case is different. All you will need is a screwdriver to loosen some clamps and a pair of pliers as well to get off some tubes. A tooth brush would be used to loosen up the gum and carbon inside, and a rag as well would help. Take off the air intake tube first, there should be a clamp or two to get it off, and then you should have good access to the throttle body iteslf. I use seafoam to clean mine just cause its what I have laying around. First I just take a rag and pour some seafoam on it and wipe around inside the throttle body to get any loose dirt up. Then I pour some seafoam onto an old tooth brush and start to brush away the deposits of dirt. Its a good idea to work in sections to get it all, then wipe up after each section. Once the first side of the throttle body is clean, and the visible side of the butterfly is clean, open the throttle with your hand and use a tooth brush to get in and clean where the throttle meets with the side of the throttle body, this is most likely the area where carbon will be built up and cause a sticky throttle. Clean it off, and also scrub the other side of the butterfly with the tooth brush and wipe it down with a rag with sea foam on it. Once done scrubbing just take a clean part of the rag and wipe down the entire inside of the throttle body, and re assemble the clamps and tubes for the air intake. Its really that simple should take you 20 minutes at most to do a good job of it.

thank you so much for help

I did same way ,I just could not beleive it how much black grasy gum was in it i had to scrab it with screw driver before i used toot brush.SO much dirt i try to use alcohol to clean section but did not work well so went in the store and bought trottle body cleaner.JUst spray few shots and it was very easy to remove dirt.I mportant thing was not to overspray to let dirt drain back .Butterfly was also very dirty so using tootbrush i did great cleaning job.I have noticed that car will not start until you put all hoses back together,because of the MAp sensor not getting any air and not sending info to ECU.
now i will wait very hot day to see if that was causing problem "sticky gas pedal"
