I am not sure what a cel is. when driving through town I get the black buildup on the rear spoiler. When I am on it the exhaust is black. The car has 40k miles on it.
I installed a Taitiec exhaust system on my '91 NSX which has resulted in the car running extremely rich (black soot across the rear spoiler). I have not upgraded my airbox or filter.
Does anyone have suggestions on what the best way/product is to resolve this issue and wake my car back up...
Exercising worked for a couple days but it is not a long term solution. Has anyone out there shopped these and know where the best place to buy is?
I am beside myself on whether to try and fix it or just bypass it. Thoughts?
Thanks,
Matt
