Just wont idle....argggggg!
Need some thoughts on things to check off and try to narrow the cause for this......
I have a Chevy 350 40 over......Brodix Tk1 heads....Holley 4150 750CFM. Engine drops off quickly and dies when I adjust the idle to about 1800 rpm. Engine throttle is crisp and revs really quick on the peddle. No smoke....but just wont idle.
Recently installed new plugs, wires (MSD 8.5mm), new dist cap & rotor.
I'm thinking must be a vacum issue......so going to get a tester tomorrow and pull the cap off of the back of the throttle plate and check.
Good place to start?.....what type of reading should I get (or should be) on the intake vacum?
Other things to check....or possible causes (i.e. timing?)
Thanks!!
