3000 RPM Idle at Startup (And It Will Only Decrease to 2500)
This morning, when I started my 02 Escape, the RPM jumped to 3000 (exactly) and stayed there for maybe twenty seconds. It then decreased to 2500 RPM (exactly) and stayed there for minutes. I tried starting it again and again and encountered the same problem: it remains at 2500 and won't come down. So I shut the car off and did several things.
One, I cleaned the TB. That didn't make a difference. Two, I read an old forum post left by Big Jim, who suggested disconnecting the battery for half an hour and thereby resetting the PCM. I tried this, as it seemed to make sense, but it didn't work.
I've done lots of repairs on the Escape myself in the past, including replacing the IACV. At first, I thought that's what the problem might be. Or something related. But what bugs me is the consistency of the problem: on startup, the car shoots to exactly 3000 RPM, then after a few seconds settles to 2500 RPM and stays there.
There are only two things I've found that will change the RPM: 1) tapping the gas pedal, which sends the RPM soaring higher, and 2) turning on the air conditioning, which drops the RPM to exactly 2000.
Any thoughts on what I should do? I haven't driven the car since this started, as the high RPM makes it very tricky to get it out of my apartment building's garage.
Thanks in advance.
