IACV

possible MAP sensor

egthomas

map sensor?
were is this located?
and whats the iacv?
ive heard these words before but never really looked into them.

Check ur IAC, not always it... but usually. Its behind the intake manifold, it looks like a cylinder with 2 12mm bolts in it.

your map sensor is right on top of the TB...just replace it. clean the iacv and see if that fixes it first.

Start by checking for a vacuum leak.
IACV = Idle Air Control Valve.

thats exaclty what mine was dointill i got the temperature hose, it goes from the head to the intake manifold not sure what is called but it might be mssed up wweird but will cause rpms to do this

egthomas

a little hose that went from the intake manifold to the brake cylinder thing, had a crack so i cut it, put it back, and now its all goood.. haha.
oh and by the way,
that "stop leak" for radiators works really good.

egthomas

were the arrows point is were the crack was. but i cut it and fixed it.

Honda-Pilot

That's a vacuum line going from the intake manifold to the brake booster. If it had a crack in it, it would definitely cause your problem.

distributer possibly?

slo_hatch

no if it was the dizzy it would quit running completely...unless you mean like the rotor button and cap. i have never heard of a dizzy causin this problem. i would check vacuums too...i forgot about tellin you to check those.
