Re: 4.3L Vortec Manifold Gasket Replace/Spider Upgrade

I must have got it right. Pixie has been idling properly since the Thursday evening tweak. Smooth powerful acceleration and fast response with no sticking of the throttle off idle. Idle hot and steady at 550 rpm.

Check engine light stayed on since it was still carrying the P0507 unexpected high idle code in the computer.

Been driving a bit, about 75ish miles and on the way to work this morning the light was still on.

Pulled up to the parking lot, engine at idle and that glaring yellow light goes out.

I love it when a plan comes together.
