2010 corolla S low/rough idle
I changed the alternator in the car yesterday, and
for some reason after reconnecting the battery and
buttoning everything up it now has a rough idle.
Does anyone have any idea where to start first?
Perhaps you left something "unbuttoned". Go back over your work.
Yeah grounds. Or you broke a wier look at your work and what ever u moved out the way look around ur work u might brook a vacume hose or ground ner ur work ..my advice ..look thier
If nothing os broke or a vacuum then u my have to relearn throttle boddy prsegers ..ether or cuse u had battrey un hooked it my be that u need to gest my guess to u but looke around your work. Ferst and make sher u check carefully
