Question about 1996 Acura RL

Low flow Egr check engine light

I am trying to smog the car and it passes no prob on the pipe. I have reset the check engine light after replacing the EGR and clearing the passages but it is still giving me the low flow EGR code. I have checked the vacuum while it was driving and it held true @6-7 lbs to the EGR while cruising. Does this sysytem work differently than most cars? I put vacuum to the EGR while it was running (15 lbs) and it hardly faltered....shouldn't it die?
I have also replaced the T-Stat as it was running a touch cool and thought that might not be letting the PIDS reset but now those are both out of the equation.... please throw me a bone....

You need to pull your plenum and more than likely the intake and clean out the vaccum port in the intake where the egr pipe connects to the back of the intake.Not sure if you can do it with just pulling the plennum or not though.Having the same prob with my 96 rl.Keeps kicking the insufficient flow to egr valve code at about 30 miles.

run the fault codes to ensure that the EGR valve is faulty. Engine lights to not always come on unless there is something drastic going on with the engine /gearbox so that you can stop the car before damage is done.

I have a 1998 dodge stratus and the code 403 egr flow cicuit malfunction comes up how can i fix this problem so i can pass inspection


Check all vacuum lines to the EGR valve, the EGR valve is between the intake and the exhaust, EGR stands for Exhaust Gas Recirulator valve. It must be able to flow properly in order to pass emissions anyway if they do a smog test.

I have code P0401 on a 2001 I SU RODEO V6


You've probably fixed this by now. I had the same problem and it wouldn't pass the smog check. I thought I'd have to replace the EGR valve but now know that would have not solved the problem.
The solution was to remove the EGR valve, plug the rear hole and use some carb cleaner down the other hole. I'd get two cans. I sprayed a bunch of liquid in the hole but it just filled up. Had my wife come out and rev the engine for a bit. Finally, the liquid got sucked into the port and I sprayed an entire can in while she kept the engine RPM up. Bolted the EGR valve back on, took it to the Smog check place and it passed with flying colors.

Egr valve is bad on my 1989 chevy with 305


You block it off before the valve on the metal pipe that runs to the EGR valve. The problem is that when you go to get it smogged you have to replace the EGR or it will not pass smog

Truble code p0400


the passage that causes this low flow is in the intake, it gets full of carbon and gunk, try running a wire through it, also make sure the EGR passes a functional test.
