Replaced the new alternator and after replacement I spun the first alternators pulley and it was spinning freely again.
I wonder if it tightened up after it got warmed up?
Would an alternator do that? Get hard to spin the pulley when it gets warm?
The poor engine performance ended up being a vacuum leak. Once we found it it is almost perfect except for a little shaking at low rpm(no throttle) as soon as you give it a touch of gas it is as smooth as silk.
We are going to try a new IAC.
Any one have any other ideas?
