It has a miss under power that is most noticable at light acceleration. All of the cylinders are firing (I hooked up a timing light to each plug wire), and all of the plugs appear to be okay. None of them are reading more rich than the others. The car tries to die when it's put in gear, and is generally just running like hell. The only thing on the engine that is not brand new is the distributor. Could my problem be a weak coil? Maybe a bad HEI module? How can I test the compnents?
Can't help ya out with anything specific. When I have problems like you're havin, I find it's usually ignition. I just start buyin or borrowin parts and throw. I know, not very scientific and could be expensive.
Are your plug wires fairly new? If they are, are they spaced properly. I've seen this posted before were the wires were too close and the spark was jumping.
The plugs, wires, cap, rotor, springs, and weights are new. Everything is spaced out okay. I'm willing to bite the bullet and just buy a new distributor, but I want to make sure that's the problem.
A miss that occurs on acceleration is usually caused by secondary ignition components . A common cause after installing new plugs is a cracked porcelain insulator , they are easily damaged while installing them . Try getting the car in a dark garage or outside after dark . Fire up the engine and snap the throttle while looking at the wires , cap , coil etc etc . I sure hope this helps you with your problem . Also if you know some one with a scope it will only take a minute or two to locate the source .
Here's a good page on how to test the coil & other ignition parts: http://www.carcraft.com/howto/53318/index6.html
There's a lot of things that could be causing the symptoms you describe, including vacuum leaks, fuel (filter, flow, carb, etc.), inoperative choke (stuck partally closed), plugged catalytic conveter, etc.

Thanks. That's a great site.
Rick,
Thanks for the tip, but I've already tracked down all of my vacuum leaks. :lol: I just can't catch a break. :lol:
