Need more details. Does it always idle high? If not, describe the situation.
I'd think vacuum leaks would make it idle lower (ie. taking off oil cap.) Could be decel valve too. Easy to test and fix if it is. |

It lopes when it is first started, then settles into a nice idle....once it heats up, the idle heads for the moon.

i take it by lopes you mean a low idle and barley turning over.
you may have more than one problem. i would look intot he following. aux air regulator (AAR). check for 12v at the connector or stuck open. WUR- check warm and cold control pressures, (WCP/CCP). decel valve.

sounds like your warm up regulator is backwards!

By "lopes" I'm guessing that the idle speeds up, slows down, speeds up, slows, etc.
Yes? |
