Running Really Rich??? Help

[lift1989]

Okay so i have a 01 Celica GTS and I have a Air/Fuel Ratio Gauge and for the last week it has been running really rich... on the way home from work today it damn near died. Every time i put any gas in my tank it does this.. it runs really rich and nearly dies but then it goes away. well now its doing it all the time and i havent put any gas in for two weeks. i have no C.E.L or any thing. but you can smell it and hear the exhaust back fire so i know the gauge is working. i have no idea what is could be

is it a wideband gauge or just an AF gauge?

stuck open injector

its a narrow band air to fuel gauge. if it is a stuck open injector shouldnt it run a code? do i need to replace the injectors or is there a way to fix that?

you need a wideband to tell you what you are really running.

Do you have the Blue electrical connector connected to the EVAP Purge VSV by mistake?

well the narrow band says its running pretty damn rich and it really is... i had to push on the gas to open the butterfly just to get it started after work today. its at the point now where i cant even really drive it.. saw some smoke coming from my hood today when i got home but i cant see where its coming from. im pretty sure there isnt anything connected by mistake cause i havent messed with any vacumm lines... the last thing i installed was some headlights...

wait a min.. yeah it is connected but its been that way sense i bought the car... and it has a AEM intake. but it has never gave me this problem before

Should be popping an EVAP CEL. But, the Blue electrical connector is usually left disconnected when a CAI is installed. The Black electrical connector should be connected to the EVAP Purge VSV. If the Blue one is connected, it will cause stalling after refueling and running rich in high temp areas like Nevada.... as it opens the Purge valve at anything below 4K RPM and you have a warmed fuel tank (lots of vapors).
