Hair line crack in exhaust manifold
Any advice ? 1997 Nissan 2.4, 4wd. I just replaced the front oxy sensor with a factory origional. Codes of P0130 ( oxy system) and P1320 ( engine missfire) remain. I did notice a hair line crack between the two ports. Is this my problem ? Should I replace the manifold ? Thanks for any advice, Bill
