Sounds like an expensive guess to me.

No luck. I'm still experiencing the same problem. Fortunately, the
valve job was a warranty job. I did notice that I smell gas when it
starts hard. It seems like it must be flooding. Any chance the
throttle body is toast?

There isn't any thing to break in the trottle body. It's just an air valve.
I'd be looking hard at the spark system.

Re: 2002 Grand Cherokee Hard to Start
When my Jeep gets hard to start, I clean the connection on the CPS with
a spray contact cleaner or WD40 and am good to go again. I also clean
the TPS which seems to help with cold starts too. When it's connection
is clean it does idle up better cold.
I have an old beast but still....
