Today I replaced my IAC again. That makes twice in 30 days.guy in the videos always says " looks the same as the Ford part , works the same" No it doesn't ! He isn't fooling me.
That tells me to replace the IAC. It's old and due for PM anyway. What more do you need to know.To me it acted like the IAC was stuck at 1200 rpm high idle for awhile
You can but why. I trust what Forscan tells me.My pressure is right there (40) per scanner. Can I rent a gauge and put on Schrader port to test it.
That's a big bullet to bite. I would do easy jobs first.Or just bite the bullet and buy 4 new ones
IDK, but I can with Forscan.I have a mechanic friend ... would he be able to do a pressure drop test using a scanner
