- Sat Feb 11, 2012 11:08 pm #294490 went to york today... stopped by advance on the way there and picked up a new main relay... still didnt start when warm.

went to another advance and picked up a intake air temp sensor(the code that was thrown) and coolant temp sensor just to give it a try. replaced the AIT and it seems to have fixed the problem. starts idles runs fine. took it for a drive, still starts right back up i even stalled it on purpose and it still starts right back up... crossin my fingers hopin i finally solved the mystery :thumb:

still have the pulsing rpm deal goin on but the starting issue is solved for the time being anyway

I checked for leaks back in the fall but didnt find any. ill check again next chance i get.

do you mean the fast idle thermo valve? I "adjusted" mine about a month ago by following the directions on this site.
http://www.superhonda.com/forum/f55/tro ... ms-259965/
it helped the idle alot along with cleaning the IACV for like the 4th time in 2 years.

how do you clean it?
