Ok, I just finished up a huge amount of stuff on my Accord including.
Changed timing belt and all other associated belts.
Replaced crank and balance shaft seals.
Replaced the water pump.
Replaced the valve guide seals.
Upgraded to a Bisi Level 2 cam.
Upgraded to Bisi Pro Valve springs.
Upgraded to a A6/H23 intake manifold (A6 runners, H23 throttle body and plenum, and two gutted IAB plates).
Replaced all seals, gaskets, and everything as I went through.
So I get everything put back together today, start the car up, and sure enough it runs and sounds really healthy! HOWEVER after running for about five minutes it starts surging (LOL, like this has never happened to anyone... ). So I reroute the coolant lines so it bypasses the FITV on the bottom of the throttle body, hoping this would eliminate my problem (so now the coolant line runs from the bottom of the intake manifold straight to the thermostat housing). Start it back up and it still surges up and down.
So tomorrow my plan is to remove the throttle body, take the FITV off and install a block off plate, reroute the coolant lines to bypass the IAC valve and leave the IAC plugged in so it hopefully wont throw a CEL.
My question is, am I overlooking anything that would cause it to surge? Possible vacuum leak? I would think if I had a leak it would show up as soon as I start the car, not several minutes of it idling.
It really gives you a crappy feeling when you get everything installed and it does this...
Any help or info would be appreciated.
