I have a 2002 ford ranger, and when it is humid outside, it will not idle properly at times.I will crank it up, let it go through it's warm up cycle, and when I go to back out of my driveway the idle soars up to close to 2,000rpm's and so I usually have to pull back in and turn off the truck, and let it sit a minute, and then recrank it just for the idle to go down. And then other times, it runs perfectly fine, and idles the way it is supposed to around 600rpm's. This is driving me crazy, replaced the IAC, cleaned the throttle body and maf sensor, put a new air filter, change d transmission fluid, and oil about a month ago, and I have noticed when I am going to work sometimes that it sucks gas by the gallon, and then when I pull up to a red light, I notice the idle is high. What is going on?
have the same problem?
