idle starts in the morning around 1100-1700- fluctuating idle (revs up and down)
Depending on the weather idles from 11-1400 or 16-1900 rarely goes past 2000

1. I don't have my secondaries hooked up, could this be the issue?
Having a hell of a time figuring how to wire them.
- also when we installed the motor, car bogged, etc with obd2 ecu. mechanic changed the idle to get it running somewhere under/near the throttle body. Have no adjusted it back yet. I wasn't there to see what he did.

2. could the idle effect the way it is running right now?

i am going to take off my iacv and clean it with carb cleaner this weekend. and check my tps sensor.

No CELS, motor ran and drove great before swap in the acura.

3. Motor takes a bit to get going, didn't feel like when i first got it. Feels sluggish in a way.


Just any other suggestions would be nice, so i can check them out as well when i get a chance. Much appreciated.
