Instead of getting a new bung drilled in the exhaust, I’ve decided to go the route of using the new wideband with the narrowband emulator and just replace the narrowband. Unfortunately, in order to do this the ‘right’ way, I have to get a new male connector to match the one on the original O2…
Colder plugs
I put some cheapo autolite spark plugs in the car today because they are a step colder than the stock temp ones. It seemed to completely eliminate the hesitation I’ve been feeling when the car is already warmed up, but I haven’t gotten to put many miles on them yet. I’m really interested to see…
