I'm Awesome
First off I have a 383 stroker 9.5 compression, 12-388-4 can, and holley 670 TBI. I have installed new 02 sensor, tips, IAC, distributer, cap and rotor, plugs, egr vacuum sensor, and ignition module.
When engine is cold, it runs pretty good, but once it heats up it has a bad hesitation under 2k rpms, it will also pulse while trying to accelerate, and when you come to a stop, the rpms drop down to stall speed and once in a while it will even die and not throw a check engine light. I set the timing at 10° advanced and I almost passed emissions. At idle its pulling about 20-21 inches of vacuum. And the other day after it died on me I restarted it and put it to the floor and it through a code for map sensor/ low voltage, but hasn't thrown it since. I know the air/ fuel mixture isn't perfect yet and timing might still need work, but any ideas?
