My '85 gn failed and the parameters are listed below. I have since changed the O2 sensor and EGR solonoid. I lost the Turbo a week after the test and I suspect that the seals in the turbo may have been passing oil through though I never saw smoke until the day it failed. I also failed the change back to the stock fuel regulator and had in the 237 TA regulator before the test. Computer chip is stock.
15 mph HC CO NO
129 .71 1765
25 mph 107 .48 1485
Failed HC and NO. I'm having the turbo fitted to a TA33C which flows more. Where am I failing and will the bigger turbo cause a smog failure.
