UPDATE - I didn't get to the IACV , I noticed a bad vacume line while I was in there, I replaced it, now here is my next question..
Cold engine, started in park, RPM's are at 1200 for less than 10 seconds, then 1000 RPM for less than 30 seconds, then I put it in gear, and they dropped to 800, after engine warmed up, rpms were at 700 or so, even in park. Is this normal ?
I understand an engine runs higher when cold, my question is, does a normal engine run at lets say 1000 at the highest, and down from there, and so forth ??? the temp is about 60 degrees F outside.. .
thanks !
I'm hoping all my problems are fixed and I can be done with this.. . .
I think that's normal rpm...
