I have a 98 Tacoma SR5 4x4 168k mi. My CEL has been on a while...the issues being the throttle position sensor (P0120) and the idle air control valve (P0505).
I am wondering how serious these are - will it hurt my taco to keep driving with the issues?
I doubt I can fix these myself w/o some serious guidance (I would like to learn - I don't want to waste a lot of time & money and screw it up even worse). All I know how to do is change my oil...
What would it cost to have these issues fixed by a competent shop? I am in the Los Angeles area...can anyone recommend a shop anywhere in LA/OC that is good to go?
