  1. So I finally went around and got the AEM UEGO wideband on my car today. I'm running 14.7 at idle 14.5 at light cruise 13.5 on light acceleration and 13-13.8 on full WOT. I also only get 12-13 psi in boost with the stock restrictor removed and full breather mods. I also have an issue where my car jerks when my fuel tank gets below half a tank. Tomei fuel pump was put in about a year ago.. What I've ready online leads me to believe that I'm running way too lean on WOT. What should I start checking first?
  2. I accidentally uploaded the same picture twice, its just cylinder # 4 that is dark like that on one side. All of the rest seem to be the same with slight color on them. So its probably an injector issue at high load? I'm afraid that it is an issue of my engine leaning out because I have my downpipe, exhaust and intakes on without a tune. Also my o2 sensor on my cat was chopped by the previous owner. I just don't understand how it could be the coils or the fuel pump when I just replaced them
  3. Today I was doing a second gear pull and at about 6000 I had a huge hesitation as if I had let off the gas and a huge pop/backfire. My power band has also been acting really funky lately, the car feels like it goes in and out of power almost. I pulled my spark plugs to check the overall health and I'll be compression testing soon, just waiting on my buddy to head over with the tester. Any opinions or thoughts on what I should check out first? I'm thinking it has something to do with fuel as I run into more problems on a low fuel tank. It seems like there might be oil on the threads of the spark plugs? The previous owner had a compression test done about 1 year and 7 months ago, I've included pictures of the test and all of the plugs. I'm still running the stock injectors and I don't know when the fuel filter was last replaced. Spark plug is a BCPR7EIX.

  4. Do you know where I can get a manual online in PDF format?
  5. Thank you for the help, I'll go through all of the resistance readings today and see if that shows me anything. I'm definitely going to go for a Do-Luck sensor, do you think the Tarzan is worth spending more money? I actually was leaning towards the nitrogen pump accumulator as well. My mechanic has one here in Japan for me already. So I'll give that a go too. Yeah, I would get random voltage drops and stuff like that too. I'll have to check that out thanks.
  6. I'm not sure if this is allowed as it's my first post but here it goes, I recently purchased a '94 R32 GT-R about a month ago and everything was great at first, and still is even in 2WD. About a week after purchasing the car I noticed that the 4WD and ABS light would come on about every 1 in 10 startups(the lights wouldn't come on for about 1-3 seconds after startup and stay on). All I would have to do is turn the car off and back on again and the lights would go away. Then it started becoming more and more frequent to where eventually it was almost every startup the 4WD and ABS lights would come on. Most times I'd just move the car to a different spot and then turn it off and on again and the 4WD and ABS lights wouldn't come on if I restarted the car enough. Now the lights will come on no matter what and I cannot get the ATESSA to work at all. I've pulled the fuses as I don't want to damage anything or potentially ruin the pump(if it hasn't been ruined already). This is the first GT-R I've ever owned so I searched the forums and saw the ATESSA fault code list. My car is pulling code 16 (lateral g sensor or circuit). So I checked my g sensor and its still white not red. I also checked the fluid reservoir in the driver side of the boot and it's a tiny bit above the max line. Side note, I used to notice my car used to do a weird clicking every 4-5 seconds in the boot and sometimes the 4WD light would flash when it happened. I've done quite a bit of research online so far but I'm not really sure where to go from here. Any advice or help would be much appreciated.
