Engine Performance problem
2000 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 116350 miles
----------------------------------------------------------------
I was a retard & installed a flushing tee (for coolant) on what appears to be a vaccuum/air hose(top of engine)... flooded my engine... got it running fine for a while... now it idles high. 3k in neutral, & approx. 1300 in gear with brake applied. Sensor/part to replace to remedy?
