I glanced over the first page and it was full of a lot of very useful information which I will be sure to use not only on my own vehicles but on any customer vehicles that I may repair it in the near future as I progress in my new profession … you’re not just out collecting thank you’s are you?! LOL
Once again thank you very much for all your great help and I will talk to you again soon, have a great day!

Throttlebody IAC and MAF were all thoroughly cleaned, although now that you mention it I’m wondering if I should do a little checking on the operation of the MAF.
As to your recommendations I definitely have to say thank you … A fuel pressure tester too huh? … Cool!
Looks like I’ve got some new toys to buy!!!
I definitely want to thank you for all your very useful input which I will be making great use of both now and in the future. Hopefully I will have the opportunity to talk to you again soon and perhaps talk a little shop.
Thanks once again

Yep plug wires properly connected .. check
No computer codes or check engine light… check
Compression checks out good… check
Fuel trims… Need to be checked… oops, no check
Going to need to pick up a good vacuum gauge,… Any recommendations on gauges? … Types or name brands?
BTW thank you for the link on vacuum testing, it should prove very helpful as I advance from smog inspector to smog repair tech.

It is a 98 Chevy Tahoe 5.7 L 4 x 4 , all repairs listed were completed within the last two weeks, I suspect a possible clogged catalytic converter or possible fuel pump issues, or unlikely but possible vacuum leak.
