I took off the AIC and cleaned it with brake parts cleaner and re-installed it and now it runs rougher and idles at 3000-5000 RPM's or it just stalls. Then I unplugged the connector while the truck was running and it made no difference in the idle speed whatsoever....so my conclusion is that the part is bad. Would you all agree with that?
Also, in the last 4-5 days when getting off the freeway after 30-40 minutes of driving, my truck would stall at the end of the off ramp everytime. Then when I restart the truck, all my radio presets were erased and I had to reset them. Could these problems be related?
