I have to try this one. The dealership says there is no problem but why does my car rev at 1800 rpm's when I start it? Hopefully somebody produces these for us guys without a dremel or tin snips. I have a lowes nearby though. Good job.

Does it stay at 1800rpm? Or does it fall down then rise back up to 1800?
Not exactly sure, but I think that's close to the starting speed.
The Mach1 starts at the speed. That is the speed that the starter turns the motor at to start the engine. Determined by Ford to be the lowest speed that the engine will remain idling/running under all starting conditions.
Now, having said that, staying at the speed for a long time, or rising to that speed when the engine has already warmed up and has been idling for a while isn't right. And could possibly indicate a problem.
Remember, the restricter plate mod, is for people who are tired of how long the RPM's take to drop down after letting off the gas, and whose cars take and excessive time to drop to a proper Idle upon startup.
