Nice work getting data posted. Fuel trims at idle are good. That is interpreted as probably not a vacuum leak. Apparently the idle is problematic when warm. Not sure if that is when PMC going into closed loop (looking at 02 sensors) or if another component is bad.I am also noticing what sounds like a semi regular pop-pop-pop from the exhaust at idle when it’s warm. Not sure if it’s related?
here are some PIDs from idle. I’ll try to get a video of the trims at idle and 2500rpm Again. Not sure why it idled at 800rpm. But the fuel trims at idle look to be within range 5%? A bit off for bank 1 I guess.
@chromebullitts I’ll likely have the dealer diagnose all of this and have all plugs and cops replaced as maintenance on a 20yr old car despite the 42k mileage
1. How many miles have you driven the car. It would seem that if you have between 50 and 500 miles on the car lately; a code would appear.
2. If you are going to put diagnosis on Dealer, you should not tell them to replace plugs and coil packs. They will do that if you tell them to; if it does not work that is on you. Then you are looking at replacing all the fuel injectors and on and on. The data should give clues before changing parts at random (desperate act). Since it is not your daily driver (?), you are going to be able to manage this. Pay the dealer or someone else (yea) the $100 or so; to diagnose, if you think they are competent (are actually going to put on scanner and evaluate data). If their diagnosis is explained and makes sense; then work with them. If not find a local (Midas) or whoever that has a newer $3300 or better scanner and know how use it. You will have to interview them; before you give them the job. They should be able to get you in and scan Bullitt while you wait. If not find someone else that wants the work. You are in no hurry now. It is February. This car is not your daily driver Im thinking? I like how the 3 stooges said it "Im thinking but nothing is happening" lol.
3. Not sure what you meen by popping noise. From the end (tail pipe) or the exhaust manifold?
Take what I'm saying with a grain of salt. I'm not trying to tell you what to do. Just giving you some ideas that might work for your particular situation. It took me a year to get my Bullitt figured out, with great patience. It is going to be a great feeling when the mystery is solved. Let us all know. I will be celebrating with you. Thanks, for your consideration.
