TB balance - high idle - Calvin

[lazlokovacs]

Chucked a set of vacuum gauges on the cali, the TBs are in perfect sync right off idle and at 3k. nice.

However, once warm, my idle is high at 1400rpm, and rich at 13.2 AFR. Seems to have happened while changing maps somewhere along the line.

Wat is the correct next step? use the air bleeds to bring it back down?

NB
*fast idle lever has been removed
*don't want to change the CO values in guzzidiag as the rest of my map is running pretty good.
*TPS closed voltage and degree value is correct

thanks as ever

I'd check the engine temp sensor for tightness, heat transfer compound and the condition of its socket.

thanks RK, been there done that...

When you say that the fast idle lever was removed, was the stop screw backed out so that the assembly is not resting against it at idle?

Generally, on those throttle bodies, you set the idle speed by adjusting the air, which is done by adjusting the two idle stops. The air bleed screw normally aren't used for idle speed adjustment.
But, since that also whacks out the TPS, I would try tweaking the air screws a little.

BTW, what value are you setting the TPS to?
