High HC levels... (update)

Thread Starter
Lean missfire drives up the HC, every time. Doesn't matter if it is fuel pressure or a vacuum leak...it is still not enough fuel.
Glad you got it to work better.
Now add timing 2-3 degrees at a time, until you can make it "rattle" on a hot day. Take out the amount you added to finally make it "rattle" and you will improve the performance significantly. Just adding 5-7 degrees makes a huge difference.

No, until it pings. Advance it a few degrees, drive it for a day. Then a few more, driving it for another day. You will find a place where it is happy.
