I'm glad all my hard work was not in vain but I am concerned about the HC's still being so high under load because I barely made it. I did some checking and came up with this list of possible causes:
Elevated HC readings during acceleration indicate ignition misfire under load. The causes could be:
Defective knock sensor;
Weak ignition coil(s);
Excessive resistance in spark plug wires;
Arcing inside the distributor cap;
Worn, fouled or incorrectly gapped spark plugs;
Over-advanced ignition timing; or
Lean air/fuel mixture.
If you have anything to add please let me know.
