Yesterday it purred. Today it pukes at partial throttle.

Man, I don't get it. Days ago I finally set the tune to factory spec on my stock \6. Threw in the SlantSixDan fuel line mod for good measure and yesterday the engine purred like a kitten. Today it pukes at any throttle opening and continues to puke when the throttle is open. It has a Holley 1920. I rechecked the tune, sprayed starting fluid on everything to look for a vacuum leak. I don't know if I should take a walk or wind my watch. I've read these 1920s can be a headache. Do I just need a bigger hammer?

I spent the weekend replacing the rear springs and front lower control arm strut bushings. Made an appointment to get her aligned, but at this point I couldn't drive the car to the alignment shop!

Hep me! Hep me! I've fallen and can't get up!
