I got my (digital)tachometer in the mail today and installed it so I have been monitoring the rpms at various speeds and conditions what I have learned is at cold start the rpms are around 1900 and once warm its around 700 in gear warm is 660s and in park with ac on it raises rpm to about 1k and I was pleases to find out that at 70 I'm turning 2500 which rather good..... This is a 1997 with 1.8 4speed overdrive it shifts under normal acceleration at about2500
