Hawwy Posted July 13, 2013 Posted July 13, 2013 When engines warm why does the idle start going up and down , but perfect when cold Quote
Socks Posted July 13, 2013 Posted July 13, 2013 The idle should not change... The only change should be... Slightly higher idle when cold that settles down when temps rise... It shouldn't fluctuate... Quote
Hawwy Posted July 13, 2013 Author Posted July 13, 2013 I know , what do you think would be causing this. Quote
Turk Posted November 3, 2013 Posted November 3, 2013 Ive got same problem, my car idles at 750 and fluctuates. Ive cleaned the idle control valve and didnt change a thing. How can i check if my tps isnt working properly? Quote

Turk Posted November 4, 2013 Posted November 4, 2013 I think ive got a vaccum leak. Gonna do a leak test first. Ive changed plugs recently no difference. Mighy change temp sensor because its cheap!!! Quote
