Eljaro,

In addition to the items formerly mentioned... try these and see what changes, if anything. Not all permanent fixes, but I noticed some changes after a few of these tests.

1) After a drive, idle your car for 20 seconds solid and shut it off. See if it diesels as bad or if it improves.

2) Retard initial timing to 10 degrees, and see if it still occurs. I'm not suggesting you leave it this way, but its a test to try.

3) With MSD, gap ALL spark plugs to .045 and try again. See manual for your MSD. It says to gap them more...

4) Check for vacuum leaks and seal them, retorque intake bolts,etc. See if it still occurs.

5) Check your vacuum with a gauge. Compare that to what power valve(s) you may have in your carb - just for grins.


Good Luck. Curious to see what you find out if you try these.
