  1. Ahsai, I have purchased a number of new o2 sensors. I think I have purchased about 8-10 now. lol... Sadly, I returned 3, of which I needed at least 1. Dang It. I am in the process of getting a total of 4 new ones installed and will give you a screen snapshot of what I see. It was a number of smog check off events. Some it could test for, some it couldnt. Some Green and some Yellow in my case. None Red. I will try to replicate and update ASAP. Jack "Soon to be Pappy" Barnes
  2. We had a cluster, when the CEL came on. I had been driving on the freeway and then got stuffed in a horrible traffic merger event. Basically stuck idling after running nice a warm... P0102 P1126 P1124 P0150 P1128 So, ya. lol... MAF was obviously pissed. I have ordered MAF cleaning fluid and will give this one a college try. I have a generic nock off replacement that I chose to not to install after it arrived in the mail. It didnt fit right and put the original back on. I have called the local dismantlers and can pick up one from them for $50 as a test unit before breaking down and ordering a real replacement. I am also getting the tank into the last quarter, where the expected bad water would be the tank that sat in it for a year. It was started and driven around the block and then parked for a period. I havent fully drained that tank or burned it off. I just keep adding new fuel around 1/4 tank. I have ordered a new fuel gas cap. I will order the oil filler replacement tonight. Might as well do this stuff anyway. My old sensors are giving around the same values, so the computer is able to work as well as it is. I believe once I have the replacement Bosch 4 new o2 sensors installed, it will adjust correctly.
  3. I am getting a sinking feeling, the units I returned were good. The sensors start out at 4.5 each, individually drop through time. Nothing like getting a concept backassward to start. Now to order some new sensors again. Ugh.
  4. Hi, Sorry for the delay, I ordered a couple of new bluetooth units (wife drives a 540 V8 stick), so I could try bonding them with the car bluetooth stereo. No luck, but I did get them to work nicely with Torque on an Android tablet I have. So, good news, we have Torque available for feedback. I took the car for about 90 mile run, before the CEL came back on. Torque says that the o2 heaters work, but that the sensors themselves were not Green or Red, it gave a yellow undefined value. I have ordered a bunch of o2 sensors off of Flee bay, and all of them were arriving at 4.0 on the Ohm test for the front, and 3.4 ohms for the post cats, when the units in my car are (ALL) in the 2.9 ohm range. 1st question, do o2 sensors burn out and go "high'? Or do they burn out and slow drop in value? I was under the impression my 1999 996 3.4l needed o2 sensors with a range of 1.7 to 2.5 each, with my units wearing out to the high side. However, I am not sure about that now that I bought some used units off a 911 with Grade A ratings. I say this, until I opened my mail, with a low miles 1996 911 (my o2 sensors are the 95-01 gen), in the mail, and it had a reading of 3.9 ohms. Which now makes me wonder if I have been returning all of those 4.0's that would have in fact worked? That is, is my car supposed to have 2 x 4.0's installed for the precats? 2 x 4.0s for the post cats? For a total of 4 x 4.0 ohm sensors? Or am I supposed to have 4.0 front, and 3.4 post cat? Or am I supposed to have 2.0 rated O2 sensors pre and post? The quality A used one in the mail at 3.9 really has me wondering which way O2 sensors wear out now. Thanks, Pappy
  5. Bad news, the OBD Diagnostic Wifi unit, is not compatible with Torque. Which is annoying since I originally ordered bluetooth, but they shipped Wifi, and I said "what ever" at that time. Guess it mattered. Good news, I ordered two mini blue tooth units that should be here in a week or so. I will install the other in the Wife's 540i V8 6 Stick Dinon, so she can track her toy.
  6. I use an iphone, but the car has a new android touch screen after market stereo with wifi/google apps. I will make sure to get theToque app for the car, and the Fusion app for my phone. Thanks for the advice.
  7. My cheapo wired one doesn't have a clue. I have a second Wifi unit which might be able to, it hints at knowing more than the dumb terminal wire version. I also have a BiL who is a partner in an Italian sports car repair shop. WE agree to not ***** each other off much, so out side of OH @!#$, I dont bother him to much on stuff like this. I will see about a quick and dirty eval from his shops toys this weekend before paying for another failed smog eval. I am currently fearing that the P0740 will throw a CEL and screw up my next smog window (65+ miles I believe)... Everytime I reset the CEL, I start over... Pappy
  8. It appears to have been a loose hose fitting. I tightened down all clamps, one of which needed 3 extra twists before it was tight. This appears to have stopped the P1124 & P1126 codes. After a 35 mile shakedown cruise, I have one code but it's a P0740 which appears to be a Transmission issue. The CEL hasn't turned on for it (yet). Fingers crossed I can get another 35+ mile run on the car, so it is ready to smog test again. Does anyone know what the minimum miles is before you can get your car tested? The first smog test I failed due to only have 55 miles on the car since I erased the codes. Pappy
  9. I swapped the old O2 sensors back into the car, and took it for a quick drive. 3 miles down the road I am getting P1124 & P1126 codes currently. I replaced the oil filler cap this week and dont see any intake issues. I will go back over the hoses & clamps but nothing is standing out.
  10. Hi Guys, I bought a 1999 996 C2 and it now has 135K miles. I lived in a state where I didnt need to smog it for a decade. Now that I live in California, I went to smog the car and had failed due to lean fuel mix issue at slow RPMs on the NOX test. Since the car hasn't had a lot of repairs on it in the last few years, I figured it was time to replace some basic stuff. I ordered a bunch of new O2 sensors off Fleabay and installed them. Boom I now get almost instant P1115 and P1119 codes. I read Lorans advice on checking the ohms... Here is what my old units read and here is what the new plug and play O2 sensors are reading Old O2: 2.7 ohms Old O2: 2.9 ohms New O2: 4.9 ohms New O2: 4.8 ohms The parts have the same part number stamped into the connections. However it's clear that the 996 is extremely unhappy with the new units. I take it that there is no way to reset the ECM to use the new ohms range... Should I replace the old units again until I can source new sensors and make sure they dont have a reading over 2.5? Thoughts? Pappy
