My 5.0 has definately seen better days. It is almost 161k miles on it and as far as i know, the engine has never been taken apart, not even the intake manifold taken off. But i was driving it kinda hard today trying to keep up with my friends STI and when we came to a light my engine was smoking. The temperature was at about 160 degrees. I kept driving it but not as hard and when i got to the next light i turned my AC off. As soon as I did this my car could not find an idle. It surged from about 200rpms up to 1k, and just kept going back and forth. I shut it off at the light and re started it and it ran fine. does anybody know what could have happened? this is the first time

If youve never had this problem before i think youve just seen the first stages of the 5.0 idle as i like to call it. Most 5.0's have the problem sometimes its the tps or iac or just because its a speed density. So clean the iac and and all other electronic components of the engine good if its still happening then keep troubleshooting it.
