thanks, gentlemen. All good advice, and I'll take it!

 

Did you get your intake gaskets replaced? If so fill us in with the rest of the story in your own new thread so we can help you.

p.s. freeze frame data is only useful to identify that a very limited number of parameters were within normal range at time a code was set. Not that useful unless you happen to be able to identify a problem from it. Live data is much more useful, and the need for a particular live data stream varies with the problem. I like to work with misfire counters when a misfire code is being set - I think it makes sense. Don't know if this is beyond the capability of your scanner or not.

will do, thanks Les!
