been spraying 50 shot direct port on my S for a couple months now with know problems running 11-1 air/fuel. upped the jets to 75 shot today and it ran air/fuel 10-1. Emissions light came on right after. im running 93 octane. can you guys help me out. i can get a scan tool but it will take a few days. The only thing i can think of is possibly burning out an o2.

 

MIght be too rich...

 

thats what i was thinking was possible to. anyone else got some advice?

 

sounds like its rich, lean it out a tad with a diff fuel jet,

 

Get the code THEN post a thread for help.

 

light went off. going to lean it out a little bit

 

why dont you see what code came on before you do anything? I think that would be the best steps to take.

 

shoot for 10.8 to 1 on the jug. and stay at 75 if you run pump gas, id say when you go racing, put in 100 octane and run 100 shot. way more fun.

 

i could prob run a 100 shot without pulling timing if im running 100 octane right? direct port running about 10.5 to 1 air fuel

 

would an apexi safc help out in this case?
