Everyone make sure you have correct injectors if you have an idle/stall/mixture issue
I've been chasing a idle/stall/mixture issue for about 3 months on my 91 305 tpi and I finally found the solution. Oxygen sensors where reading rich but fuel pressure was low. Asked PO about injectors and he said it had 24lb injectors. Stock is 19lbs. Big difference when you have no other mods. So I'd you where having a similar issue, make sure you have correct injectors/stock parts. Big thanks to everyone on this forum that helped me!

More than just size, if you change injectors, Voltage offsets and other tuning may be needed. Also, when looking at flow ratings, the pressure the rating is at is important.

Well, good news is there is no vacuum leak. Used a smoke machine and there are no leaks at al thank goodness.
