1994 2wd 22RE toyota pickup rough idle when waiting at light and shakes when in reverse
Hello I have a rough idle when I'm waiting at a light. I also have a really rough reverse. I have been trouble shooting and i dont know if it is due to the EGR system since i have a check engine light code 71. I replaced the egr valve and cleaned the throttle body but I dont know what else to do. Also one of the tests I performed was applying vacuum to the EGR valve so that the engine stalls but mine doesn't. What should I do?
