2001 Ford Explorer-Shaking at 3,700rpm in Neutral
Hi Everyone,
I just changed the oil for the first time to my 2001 Ford Explorer 4.0 SOHC V6 ,which I bought six months ago. I accidently ran the engine to about 3,700 rpm when car was in Neutral and found the engine had a big shake. Am I not supposed to do like that? or my car really has some problems? I am totally new about car maintenance. Pls help! Btw, driving on the highway seems smooth but never ran up over 2500rpm. Ray

Re: 2001 Ford Explorer-Shaking at 3,700rpm in Neutral
Can't say for sure on your 2001 Explorer, but many newer cars have an overrev limiter to prevent you from over-revving your engine when in park or neutral. Often, that limiter is around 3000-3500 rpms. I'd suspect you hit the rev limiter.
When the limiter kicks in, it shuts off fuel to cylinders so it feels the same as a misfire. -Rod

Correct shorod. The PCM shuts the fuel off and on to keep form damaging the engine during an overrevving condition. So, just try not to do it.
