Hello all.
I'm having some minor problems with my 5.0l in my 88'bird. In park, when I rev the engine, I get some hesitation/skipping/popping at certain rpm. It starts off around 1200, disappears about 1800-2000, then comes back harder from 2300-2600 rpm. But ONLY during those times. Will go all the way to 5500 from there with no problems. Also, when driving down the road, if I am just barely touching the throttle, it will skip and hesitate some. When driving like normal, or hard acceleration, there's nothing - smooth as glass almost.
I have checked the timing (seems happiest at 12` btdc). New wires, plugs, air filter, replaced the timing chain when the cover gasket failed (6 months ago). There are no mods to the engine (hopefully rebuilding soon!!!) except for a
65mm tb +67mm egr, MSD 6A, and MSD tfi coil (both 1.5-2 years old and eat 75 amp alternators for breakfast!).Thanks for your time in reading this, and hopefully someone may have some answers!
