2002 Toyota Tocoma 2.7 99000 miles:
After driving highway speeds (60 to 80mph) 15 miles or more, engine will not idle down for 2 to 4 minutes. Idle speed will hold at approximately 1500 rpm or surge from 1000 to 2000 rpm for two to four cycles then hold at between 1400 to 1800 rpm. I have always changed air filter and cleaned throttle body assembly at 30k miles intervals. This problem started at approximately 55000 miles and I have struggled to find solution ever since. There is no codes when tested and engine check light is OFF. Any thoughts?
have the same problem?
