    I have a 2002 with the 2.3L DOHC 4 ,manual trans. without A/C. On cold start,it revs up to 2000/2500 rpm and then gradually slows to around 900 long before the engines warms up. The factory shop manual doesn't seem to provide any answers. I need to fix this ASAP. The truck only has 49,379 miles.
    Thanks in advance
