Emissions helppppp
Hello everyone,
I have an 88 IROC Z-28 with the 5.7L. Ive failed emissions 3 times in a row now. To make matters worse the more i do the worse it gets. Here is the layout. Ive changed the oil, plugs, checked for vacuum leaks. I found the TPS was off and so was the timing so i corrected them and ive run enough of that "guarantee to pass emissions" injector cleaner and seafoam through my car to have a new engine. I also changed the fuel filter yesterday and i also have brand new air filters. It has new O2 sensors and the pcv valve works fine. THe only mods i have done was install an airfoil and took the screens out of of the maf. the car isnt throwing any codes and my exhaust smells rich. below is a list of my emissions report
