I really suggest Start your own thread and if you are lucky a few members with service experience may help you?. There is several basic questions that need to be established first.
Your thoughts may be that the problem is the same but how and why they to you may be the same I am sure will be much different.

 

I'm really not familiar with newer vehicles which i know that 97 isn't new by any means but I come from a old school hotrod background so im not familiar with all the sensors and etc. that the 97 has so any help would be greatly appreciated. I've already replaced the idle air control valve, cleaned the mass air flow sensor, replaced the purge flow sensor and solenoid, changed the vacuum lines, changed the dpfe sensor and probably a few other things that I'm forgetting

 

Hmm so you just want to continue ...and just not start your own thread.
Qualifications: so let me get this straight you only worked on vehicles pre 1960 and if you even think about that a little more pre 1900's. Because you are relating sensors as the pretense for your experience level? LOL
Hot Rods always had sensors from the 1940 all the way past the 1970's to present. You now own a vehicle that has OBDDII and a PCM . While I understand what you are suggesting your capabilities are you also with me remind my of the constants customer that purchased a Holley 600 cfm 0-1850 and returned it always claiming an internal vacuum leak. .

 

just made my own thread
