  1. Going through similar experiences and I'm learning as I go but seems to be vacuum issue. I would re-check your work in regards to putting back the TB and piping/sleeves. I'm close to solving my problem but I found when I took my TB off to clean I did not do a good job of making sure the sleeves on both sides of the TB were seated properly. Once I straightened that out seems to be OK.
  2. My plan is to take another look tomorrow with a fresh set of eyes and patience. Right now there is no CEL but I'm sure it's coming. Drove it today for about 15/20 miles and on the highway driving spiritedly 🙂 It's worth another investigation of the sleeves and clamps at a minimum. Plan is to loosen up and see if I can rotate them (sleeves) and inspect for any cracks, etc. I know I tightened them pretty good so gonna try and get them snug as opposed to tight. The sleeves and seal gasket for the TB are relatively cheap so not super worried. Also going to stop by the local Indy in town and see what kind of place they have as well. As much as I would like to do it all myself sometimes it makes more sense to pay someone with a lot more experience than me. Its a big difference to read about it and technically understand the problem than to have actual time working on these cars day in and day out. Can't compare. This is not a daily driver so I have some flexibility from the standpoint I don't need to rely on it every day.
  3. Wow, that is an work or art! Good for you, I'm not sure I'm that motivated but its good to know you can make a smoker on the cheap.
  4. Yes, that is exactly where I screwed up when I initially was going in the wrong direction even after I changed the 02 sensors. I went back in and really took a good look and found on the bottom just like you said was not right. Loosened everything up and I thought I got a really good seal this time but maybe not. It's VERY possible I overtightened them too. It also could be the gasket between the TB and the plastic tubing. Whatever it is its not horrible because like I keep saying the car is running amazingly well. I might buy new rubber sleeves and a sealing ring for the TB and change them to rule out those as being issues. I can and will take it apart again and inspect but at that point I have them off and all apart might as well change them after 20 years regardless.
  5. So in thinking this through I have two options. 1. Take it to an indy with a smoke machine and just nail the problem and yes it will cost me some money but overall in 19 years of ownership I've spent very little on a 19 year average. 2. Continue to troubleshoot on my own with everyones help. Flip a coin. I know I'm close...
  6. Thank you sir, when I put it back on the first time (TB) it was a bear fight to get off and on so maybe I did rip one or both of those rubber sleeves...thanks for the .02...
  7. That was the next question I was going to ask you. There seems to be a new Indy in my town who specializes in Porsche which I might give a shot at. Buying a smoke machine for this one problem is probably not the best decision although it does seem cool. I deleted the CEL and took for another drive with no new CEL but my gut tells me it's just around the corner. I also did the oil cap test and it did change idle when I took the cap off so more than likely some kind of vacuum issue. I might just for one last shot take the TB tubing off and put back on again as that is the only thing I touched vacuum wise but bottom line is that smoke test would tell me right away.
  8. I'm back!!!!!!!!!!!!! So put about 50 miles on since last post and again, car is running amazingly well but then this happened 😞
  9. I'm looking to get some info on AK I & II. Did some quick searches first and info seems to be thin unless I missed something. These are the questions I am trying to answer. 1. Pics of both so I can see the difference. 2. Install instructions. 3. Part numbers for both. 4. After market options. I see a bunch of eBay but hard any with any install kit with them for sale. Thank you.
  10. Fair enough. I've only ever used 92/93 in the car. For now just going to leave it and enjoy the ride. Thanks again.
  11. Yes sir, thats the lesson here and I thank you for teaching/reminding me that. I'm an IT guy by trade and I understand the troubleshooting process with everyone else's stuff except mine. Understand neither of us have a crystal ball but does it make sense proactively to change the other two 02 sensors? Not for age but for time seeing the car is close to 20 y/o. When I took the PC sensor out the tip was white as a ghost.
  12. So, it's fixed and I hesitate to say running better than before. First, thank everyone for their help especially JFP with the cool head that got me off the ledge. I'll spare everyone the drama but there were two main issues, one was the 02 sensor was bad, I didn't want to wait so bought one local (Bosch), I actually changed both because I was under there and they were close to each other. Secondly, I put the plenum tube in cock-eye'd, I thought I had a good seal all the way around but that was not the case. Once I fixed that seal (leak) issue, changed the two 02 sensors and put back my original MAFS it purred like a kitten and I took it out for a beat down run 🙂 More than likely going to change the other two 02 sensors but for now I'm going to enjoy this beautiful early Fall day. Again, thank you for the help.
  13. Thanks cr, I'll report back when I get the parts and install...
  14. I hope I'm that lucky sir, it doesn't sound great right now but I have to have a little faith...
