i ran my car-88 gxl na- ran out of gas the other day and since i put some gas in it it has had 0 power and ive checked everything i can think of i cleaned the injectors changed the fuel filter and i replaced the afm with a close-to-new one i have custom made spark plug wires and i have a spark plug cleaner and cleaned those. i notice the last cat glowing tonight. i have an a\f ratio meter and it is so below the lean lines, and i also have a boost guage (plan on a turbo swap) and i have noticed that the guage reads 0 vaccuum when i am driving at idle i have about 17 lbs of vaccum so i know that is normal but the 0 vaccum at a drive indicates a clogged exhuast. i think the exhuast is cloged and the back pressure from the exhuast not exiting the engine is causeing my lean condition and the fact that i have no vaccuum to suck in new fuel into the engine is my cuase of no power. anyways id like yalls opinion.

 

Cloged Cats.. What else do you want to know?

 

i just want to know if people agree im pretty confident about the cats but if someone has had similar problems and it turned out to be something other then the cats then id like to know. just curious thats all. this is a forum right? people ask questions and talk about things.
