This is 9000 AERO(1994) with 125K miles- The emission test shows high NO -on all other aspects the car passed. It failed only on NO. I need to fix this ASAP. Q: the car had its head gasket blown- we replaced- later we found that the Turbo is leaking oil into the exhaust- we replaced the turbo- It has a new muffler from one of the chain stores. All these repairs were done in the last 3 months. Is it possible that the catalytic converter is damaged during the oil leak into the exhaust? And if so is there a way to fix the problem? Q: Would a back pressure test on the catalytic converter show if the unit needs a replacement? Q: if it is not the catalytic converter what else could cause the problem with NO only?
