![]() Side note - I don't have any timing marks, anywhere, at all. Idle air controller was clean and good and throttle body is clean (supposedly) so did I waste my time even bothering with the 02 sensor? What else could it be? I have to replace it now anyway. Am I missing something easy or did someone just tighten this thing down way too much? Is there an easy way to replace the O2 sensor? Below I'm going to link a short video of the way the car idles, you can see the big dip it does every now and then but the gist is the RPMs wobble around, sometimes worse than other times but especially bad after sitting awhile. The only things we can think of is removing the exhaust or the manifolds (6.5 hours of labor, not happening). I've managed to move it slightly, but not enough to get it out with a ratchet and obviously my efforts have made things worse as i've got from not having a code to have a code. I need advice, how do you guys get this damn thing out, we can't get an angle good enough to remove the damn thing, it's in too tight and we can't get it out at any angle. Why am I now getting a code 22? Probably because we broke the sensor trying to get the damn thing out. I checked my codes and the only code I was getting was 22, we replace the temp sender (again) and now code 22 is gone but now I'm getting a code 21, the O2 sensor. I was looking around on here for idle issues and I saw O2 sensor come up and though "Hey, that's pretty easy, just unscrew the old one and screw a new one in". I replaced the alternator (it wen't bad) the rubber bushings holding it at the the right angle were dried and cracked, we've replaced them (the belt only squeaks a little when you first start it now). I didn't really drive it enough prior to this to notice if the bad starting and idle only starting after replacing stuff or not, but I'm pretty sure replacing stuff made it worse. The fan wasn't coming on the the temp gauge wasn't working so we replaced both temp senders, gauge works now, fan works now, but the car starts like ass in the morning/after it sits for awhile and it doesn't idle right. ![]() After getting the vehicles I had all the belts, fluids, plugs, wires, cap, rotors etc. It had less than 47k miles on it when I bought it, the lady put less than 200 on the car from 2011 to 2019. I've bought an 89 TC, original owner was this ladies father who passed away, drive it a few times a week etc. But I've run into an issue and can't really put it off any longer. I was going to make a large introductory post on the vehicle I bought, problems I'm having, things to fix, etc. I have been lurking these forums for about a month or so now, trying to educate myself on the mistake I might have made before actually posting.
