Sorry for the first post, but i've been looking everywhere and i cant find any information on the matter, and i'll try to cut a very very long story short

Im 21, and have owned this car for several years, in 210K miles on it already but its holding on strong (for the most part). About a year ago, my car started showing idling problems, amongst other and my dad brought it to this guy, he worked on it, didn't fix it more problems arose, and so on and so forth, my father still brings it to this guy and we get into pretty heated arguments from his faith in the guy who owns the back alley garage (i found a deliberately 3/4 cut through wire for my battery terminal, still not enough proof, and this was proved by another mechanic).

So as many problems as this car has i just have two questions for anyone who is willing to help me

1. I found a switch whilst cleaning my car, i'll supply pictures if you guys ask, its by the petals, so if you were laying on your back with the petals touch your head, it would be right on your nose, any idea what it might be, been googling for hours haha

2. This idling issue is getting tiresome, car first starts works great, if i go above 50 and come up 2 a stop light, car idles extremely low and the car starts to shake, restart the car, it pretty much goes back to normal and it repeats the same cycle right after when i go over 20.

thank you in advance for anyone willing to help out this new guy

Edit: oh and pertaining to number 2, the oil pressure completely drops

 

Use Carb cleaner to clean your EGR valve and you Idle air control valve. Start there if you haven`t yet. Could be a bad coolant temp sensor also.

 

I seems you idler + Throttel is blocked/dirty you need to clean it up at that mileage and yes i agreed with almungus's suggestion. Good info

 

order and replace your idle control valve to solve the stalling problem. ours did the same thing for about a year until i finally spent hours online researching the problem. rockautoparts has the valve you need for under $100. good luck.
