I posted this message a while back. Someone please help. My 94 Ford Escort 1.9L is still revving high on initial start up. I know this is normal, but why should it take 5 minutes be fore the tach drops down to 900 prms? I changed the Idle Air Control valve- nochange. The car never over heats or anything. Went throught the entire summer without it reaching to the half mark on the engine temp insdicator. Someone recommemded the PCV valve? I dunno.
P.S I have a cold air intake., Don't know if that info will help.
