Hello all, I have a 2004 Toyota Solara 2.4L with an air-fuel ratio of around 9.71:1 at idle. From my understanding (watching the videos) this is running a bit rich and I’m not sure where to go from here. The long term/short term fuel trims are with in reason I believe. Would I have to take the car and get the ECU calibrated to stoichiometry or is there something else like a leaky injector or something that would bring the AFR back to normal. Thanks in advance for your time.
