what are the correct running rpm's for 190E? Mine (85, 2.3, 119K) has the following:

idle in park: 1300
idle in drive: 900
at 45 mph 2000
at 55 mph 2500
at 65mph 3000
at 75mph 3500

are these normal? Also, I read somewhere that the rpm drop when shifting from park to drive should not be more than 50 - mine (the drop) is 400! With the A/C on in drive, it goes down another 150 (to 750). could this signify a problem?

thanks!
