I've been running a JDM 4-1 header with a highflow cat and stock exhaust for the last month.
The only other mod I have is a Mugen intake. I'm also using the stock ECU.
Yesterday when I was driving my car started going crazy, idle was bogging occasionally, when it was ideling it was quite low, car shut off a few times when I came to a stop. CEL also came on after a while.
I took it to a local mechanic who specializes in Hondas. He hooked it up to his Snap on diagnostic and it read that the car was running very rich.
He also reset my ECU so I couldn't check the CEL flashes.
He believes that my JDM header has destroyed my primary 02 sensor. If I replace it with a new 02, will this occur again?
is this possible? he recommended that I convert to OBD1, but I don't want to go that route because I don't plan on doing any other mods than what I already have.
Anyone having or had this same issue?
