Hi all! Just discovered this forum on my hunt for diagnostics info. I've had my 2005 Corolla CE 5spd for about 3 years now, never lets me down. Over the years the idle's gone rough, almost stalls out sometimes.. It was throwing lean condition codes so I just replaced my manifold gasket and the idle got even rougher. Is there a way to adjust it even with throttle being electronically controlled? Or would I need a tuner for the ECM?

How many miles do you have on the car? Have you look at the throttle body to see if it needs cleaning? Here is a guide if you decide to tackle it yourself.

140k. Was thinking about doing a once-over on all fluids and fuel systems. Like I said I've done the intake mani gasket, also cleaned MAF, put in new a/f sensor. Still want to do seafoam or redline si-1, trans fluid, tb, iac, fuel filter. Pretty sure none of that has ever been done. Also I did something autistic to my airbox after I watched a video, and it sounds great, but my idle sucks even more now.
