OK, truck is running great. Trying to iron out the last hiccup and see what you guys think. Currently the truck idles nice and smooth once warm but, flip the A/c on and it has a shake only at idle. Flip the A/c off shake immediatly goes away. Wierd I know but whatcha think?

You should be idleing at no less than 650 RPM with AC off.

Patience me @$$, I gotta kill sumpthin..... Oh wait.... wrong thread...NVM

Oh come on Capt, just get a variable pitch prop.

It idles at around 750 A/c off and doesn't really flutter. Click the A/c on same 750 but with a shake?

I'll check them next time I get the chance. No shake on old pump tho?

Shake could be a bad A/C clutch.

All the injectors are working good? Hmm.
