After putting fuel dampener bypass I have problem with low rpm.

Engine is running and accelerating fine at all rpm but if I keep it at 2000 rpm or higher and suddenly let it go to low rpm it will go lower than 500 rpm and turns off. If I do the same slowly everything is fine - it is running on low rpm without any problems.


How can I fix it?

I dont have that problem. the only difference I noticed is the car idles louder and I can hear this vibration of fuel.
I dont think it would effect the rpm of the car cuz its just a fuel line, unless there is a leak somewhere. pop your hood after driving around and smell for gas leak.

You must have disturbed a vacuum line somehow since the instalation of a FPDB does not affect idle RPMs.

Its possible that by doing the bypass you have somehow (with a faulty FP regulator) caused the car to run slightly rich. This can cause dying on decel.

is this car by chance an auto? if so that will asnwer alot. they have vavles that control your idle when you abbruptly let off the gas. When they go the idle gets funky.

Hope that helps

It is 6 spd.

While dying on decel car runs very rich - I can see it on my A/F monitor.

You have a open air BOV and stock MAF? I don't see how a damper bypass can cause this problem, it shouldn't make a difference.
