To preface this, the TTA has 84k miles all original and has never had a real issue, always ran strong. took it off the road for a bit for primarily suspension work. So the TTA has been back on the road for a few weeks now, haven't really gotten the chance to break in the new suspension but that's not the issue. Out of no where the idle sounded super groggy and then engine light popped up for a split second, both idle issue and light went away. Threw a scanner on it and the 02 sensor was throwing a lean mixture code. Just replace the sensor right? I've never had a scanmaster against all better judgement and finally got one after realizing this isn't a car I should just be fucking around with. I replaced the 02 sensor right before I used the scanmaster and went to check all the readings. Tps is 44, IAC is normal, int/BLMs stay within range during normal driving, but my CC's read super slow, between 3-4 a frame, with some outlying days where it runs normal upon cold start but that's it. It's a brand new GM sensor. I also rolled into boost to see if I was getting knock, I felt the car obviously leaning out on the top end and at about 15 psi I look down and see 7.8 degrees of retard. Let off and decided that's enough boost for a while. The fuel pump was replaced as well as every spark related component, the injectors are original and old as well as fuel pressure regulator. My first reaction is to replace the injectors and regulator and see if there's a difference. I just would like any kind of opinion on this, maybe something I'm missing? I'd like to keep the car original but it seems as if that's doing more harm than good. Unfortunately I had been driving the car in these same conditions for a while and have gotten into boost several times without a scanmaster, I guess I'm lucky nothing has happened yet but I'm almost at a loss since this issue seems to have come completely out of no where.
