Welcome to the 'Texas ZOO'!! The 3.2 is a solid engine, in my opinion. Usually, just a bunch of little things to track down in regards to the check engine light. Mainly time consuming, lol. There's lots of help here in this forum, just do some searching, and someone has probably already resolved some of the same issues your having. Then, poke around and look at some of the rigs that other members have built, to give yourself an idea of how mild, or wild, you want to go.
Maybe this fall, Oct/Nov, we could do a hill country Isuzu trail day.
Don't take life so seriously, it isn't permanent.
If all else fails, give it more gas. It may not solve the problem, but it will end the anticipation.
