So my check engine light came on. I did the whole paper clip thing on the how to section. Came up that the second o2 sensor was messed up. I changed the first one but, i cant get to the second one bellow it. Did any one have an easy way of taking it out?? What tool was used? I can't seem to find one that fits. It's a 95 gt. Thanx for any and all info.
