jus found out i got a code 43 did some searching around and found out that the fuel pressure regulator was bad it as letting fuel go back through the vacuum line. my question is does anyone know where i an find a thread on how to replace it and if that would cause an irratic idle problem

 

Can you define 'irratic'?
Next time you open the hood look for the little sticker that shows WHAT YEAR the Accord is.
Usually there are 2-10mm bolts holding the F.P.R. on the rail.

 

yea put your year and model in your signature so we now what your talkin about

as for problems with erratic idle u should be able to find many threads about that, search and then post back with any questions, i had problems with erratic idle myself for a while but did end up fixin it.

 

Its a 94 ex and its idle between 1000 and 2000 and i cleaned the iacv and its still idling that way

 

Check coolant levels be sure the block is burped thru the 12mm bleed screw at the T-stat housing.
If that is all well and good, adjust the FITV. It lays sideways under the throttle body intake opening.
2 phillips screws hold the cap on, then inside is a nylon 'split' screw with a brass cone sticking thru the center. Turn the screw in a couple turns, you should hear no air bypassing in there when the engine warms up.
