Hey guys i bought my first Honda! Its a 91 Crx HF. but a few questions: 1. I have no idea what engine is in it? 2. When i fresh start in the morning its at 1500rpm, then when operating normal temperature it drops all the way down to about 400rpm is that normal? Or is there any way of fixing this? heard something about Fast Idle Control Valve, anything wud help 3. No a/c. Radiator looks fine but i noticed the fan doesnt come on. Help? 4. I now pronounce you, Man & Honda. You may now kiss your paychecks good bye!
