   The tip temperatures can cause detonation/pre ignition. Modern cars have microprocessor controlled everything. Carburetor cars aren't that precise.

   Thanks for the link.
   
   Yes I looked today & the distributor is the 1112109.
   
   To remove the TCS I just remove it & plug the hole correct?
   
   Mine does not seem to have an EGR valve.
