O2 sensors and the EGR

2 quick questions.
1- I have read on here people have cut out their front cats alnong with the front o2 sensors? How can this be done without setting of CEL?

2- My car keeps throwing a #43, which could be the EGR circuit, value and /or seliond. Could this also cause ruff idle and poor performance? the reason I ask is the car worked so well for about a month with this problem, then it really went down hill, no power, ruff idle etc.

Its a 94 svx and without this forum I don't think I would of bought it. thanks for sharing.

The 02 sensors are in the pipe in front of the front cats, not in them. I don't think anyone has removed the 02 sensors.

Right, but I thought I saw a post where someone removed them and just used the third cat and sensor. Also would a bad EGR cause a cherry cat?

Only the 96 and 97 MY have the third O2 sensor.

Welcome to the site. Where in Canada are you?

You mentioned error code 43. I think you mean 34 correct?

mine did threw the same code after i started driving it again. i replaced the egr valve and it threw the code again and continued to run badly at idle. i noticed, however, that it would only throw this code after it stalled. i changed my o2 sensors and the problem went away entirely.

hope that helps some.
