Ok guys!! Here we go. I have a 1994 Honda Del sol SiR (b16a3) and it's been turbo for the pass 2 years... Its been tune on hondata s300 v1.. and never had issues with it...I drive this car everyday!!! But a few weeks ago it's been idling pretty rich ... It stays at 11.1 AFR.. Keep in mind my engine coolant Temp is @ 185F and my vacuum pressure is at 20-21 inches...I thought my o2 wideband sensor was bad so I change It (AEM wideban) and no change.. At normal Cruise speed my AFR is at 14.3-14.8 and at WOT is at 11.7-12.1... Please help..

Check the fuel press, have you changed anything in the tune? Are you idling at the same vacuum hg?

i replace the fuel management just incase. But no change. I haven't touch my tune.. my vacuum is still same for the pass 2 years.. I might have a bad injector

Pull your plugs and check them. If one of your injectors is dumping too much fuel it will show on the plug.
