1997 Toyota Avalon Q&A
1997 Toyota Avalon Question: Why does my idle up and hesitates ?
Light in dash on! Scan test needed to ckeck throttle position sensor!! - pushrod
poss vac leak at intake manifold? - globalhelper
I agree check intake manifold for leak. Let car idle then spray carb cleaner where intake meets cylinder head and around any vacuum hoses if idle changes you found leak. - Mobile Tek
