High rev when starting
I am having some problems when I start my Ranger it revs high then it will idle out. This is don't matter what time of the day it is or temperature. I thought maybe you guys have more experience than me and/or this happened to you or some. Help guys and gals!!

Re: High rev when starting
Welcome! I asked this same question a while back, and was told it's normal. 126k on it, and still, so far, so good. I always thought, cold engine/no oil pressure/high rpm= bad. But the older I get, the physics get fuzzier. One of these days I'll run it by the guys at the dealer.

mine idles high at start as well. Once the engine heats up it slows back down. Depending on the weather it can take 5-10 seconds or what feels like a solid minute. Either way it's normal on older ford engines

My engine is brand new, 27,000 miles on it and it does this.

I always hear it revs up to get the oil flowing. Mine will usually shoot up to 2k rpm and over the course of 45 seconds lower to 900.

Re: High rev when starting
Thanks Guys!! I was kinda worried. I thought it might have been some sensor or something.

Re: High rev when starting
sounds like an issue with the sensor going to the charcoal sensor which is known for doing this. and welcome to frf

After 10 years, and 125k+ miles, it still makes me wonder. Makes me wonder how much metal to metal rubbing I've had at 15-2000 rpm with zero oil pressure. But like I've said before, the older I get, the fuzzier my physics gets, and somehow the engine seems fine.

Oh? I'll file that one away in the memory bank. Didn't know that.
