HI, I purchased a 79 malibu all original right down to the 305 with all the emission in place. I'm having an issue when taking off or going up hill, it looses power and there is a slight miss. Removed the cat, New battery and alternator (good voltage) I've changed the plugs (set the gap) , wires, cap, button, swapped out the coil, module, installed a new ERG, checked the timing, Checked for vacuum leaks, pulled the valve covers checked the springs and rockers. Timing was dead on, fires up at the turn of the key, runs fine while normal driving. What am I missing ? Any help would greatly be appreciated.
