Throtle sensor - 2004 Proton Gen-2

the throtle position sensor is located on throtle body across from cable conections and yes the throtle position sensor can cause shifting issues

p0120 means you have a throtle position sensor problem could get expesive if throtle body is bad p0505 is same problem it means throtle idle controle valve problem hmm short bad ecm or bad throtle body hope this helps

TO clean the throtle plate use a small tooth brush and some throtle body cleaner. remove the intake hose, spray the throtlebody and then open the throtle plate and spray plate , use brush to clean body and plate then spray clean try not to spray to much into engine , after its clean then start the engine you may have to hold gas pedal down to start as it going to be a little load up with fuel from the cleaner, some time sit will start up on its on and run a little rough for a few seconds and clear up. As far as the mass sensor this needs to be cleaned with mass air flow cleaner, this is a spray like the throtle spray but is made for that sensor and drys fast, spray the two sensors inside but dont touch them or move them spray as close to them as you can to clean them, good luck.

Check your IAT sensor, located on the top of the throtle, and calso check your Throtle possition sensor.

I have a 2002 and I had to replace the throtle body and it now perfect. The throtle position sensor went bad and you can not just replace that one part. You have to replace the complete throtle body and it is a dealer only part.

sounds more like a timing problem, probley the timing chain and gear

usually when vehicle shuts off when giving it gas is--is your fuiel filter plugged! gas not reaching injectors.

ok, this is simple to do but I would get the Chilton for your car so you can have pictures of what to do. You can get the chilton at the parts store, or the library. It sounds like a throtle body sensor or the throtle body itself, but could also be your air idle control sensor. go down and buy some mass air flow sensor cleaner and a BIG can of carb cleaner. First clean the mass air flow sensor neer the air filter. then remove the throtle body it is held in by 4 botls and you may need a new gasket, NO GASKET GLUE. Now take that big old can of carb cleaner and start cleaning in and out. also down into manifold. clean everything. Now put it back together, remember 4 bolts and no gasket glue. if the problem continues replace the throtle body sensor. and then the idle air intake. It will be cheaper to take it into the part store and have them put it on the computer. They can often tell you what sensor it is ahead of all this but don't let this stop you from cleaning out the throtle body, it will make your car run better and longer.
