Anybody in the OKC area have a smoke tester for automotive exhaust systems? I’m trying to pinpoint a leak in my exhaust so I can get my EFI to work right again. If anyone has one I can borrow for a few minutes, I’d greatly appreciate it.
Very sensitive O2 sensor any small leak or misfire will give a lean reading and begin to richen up the mixture.I'm surprised it's that sensitive. Good luck with the search.
