Dead on the money I've been working on this for three months please help lol Idk what else to do oh yeah the problem is at idle after warmed up idles at 750 and all the sudden just does out of know where but starts right back up Everytime and I also replaced iacv and fuel filter when it dies it acts like I turned the motor off it makes no sense!!! I've checked the harnessgrounds and cleaned them especially the thermostat housing ground still no luck I also replaced fuel pump with the crv fuel pump that the engine came out of and also adjusted valves to spec any ideas would be help thanks guys!!
