My 350HO w/ TBI is in and I've got a mid-rpm range stutter that reminds me of a bad fuel pump if it were a carbureted car. The engine stutters and the tranny won't shift until I back off a little. Is the fuel flow from the stock pump enough for this car? Is it a fuel pressure issue? Is it an injector issue (Holley 670 - delco 65pph, I believe)? Is it a timing or fuel map issue? (custom chip) What's the issue!? I thought it was the knock sensor pulling timing out, but I swapped all that and it didn't help.
I know a few of you are running this engine w/ TBI. Have yo encountered any of these problems?
It's makin' me craaaazy!
