I have a 92 ls teg. It sat the whole winter and I would turn it on once every 2 months. I cleaned iacv, new tps. My car needs a doctor, is there 1 in the house? Engine light turns off like normal and never gives a signal. The idle bounces up and down between 1000-2000 rpms. And when I drive it feels like it wants to idle the whole car. It would do for a litte bit and then stop.
