I know the problem, now how do I fix it?

I recently ran a scan on my 1991 accord and found that the problem was this:

EGR - exhaust gas recirculation lift valve
Exhaust Gas Recirculation (EGR) Valve Insufficient Lift

All this is like a differnet language to me, if anybody can help it would be greatly appreciated. I have done searches for this but can't find anything.

you need to replace EGR valve.

could be expensive replacing an egr valve is rumor ive heard. go to autozone, or autoparts store, pick up a manual for your accord, dont buy it unless you want it, just flip through it find where the EGR is and remember what it looks like, hit up a junkyard and snatch one off an accord like yours, replace that shit and keep on truckin! or.....accordin! just my opinion ((id buy the book its good to know your car inside and out))

yes, knowledge is power.

before replacing the valve, make sure that you have vacuum going to the valve off idle.

For mwenz33, vacuum to the egr valve comes from the egr solenoid which is controlled by the ECU based on inputs from the coolent temp, engine speed, speedometer and map sensor. So off idle, you will not see vacuum, however, you can force the solenoid valve by disconnecting P4 on the control box (near the engine compartment fuse box and connecting 12 v + to black/yellow wire and neg to the pink. (Connect to the wires going into the control box only.) The valve should acutuate with about 8 " of vacuum. To test the EGR valve, connect a vacuum pump to the egr and draw 8" of vacuum. Clamp the line and see if the vacuum bleeds off. If it does, it is a leaky valve. Also with the engine running, pulling a vacuum on the egr valve should cause the engine to run very rough or stall. To see if the egr valve is moving full travel, the easiest way is to probably remove the valve and pull a 8' vacuum and see if valve completley opens. You can also check the egr lift sensors but it requires a harness to get to the wires so you can hook up a voltmeter.
