So I cleaned my cruise control radar on the weekend and now my cruise works perfectly again. Let my car idle for 5 minutes after a big drive when i got home, . Go to turn it off and the check engine light is on, I thought it would just be the brake pedal sensor, took for a spin with the brake pedal switch "off" and it still didn't clear. So this morning I checked the codes and I get 0235 and 0171

0235 Turbocharger Boost Sensor A Circuit Malfunction

0171 System too Lean (Bank 1)

Anyway I am pretty Stoked :no: , thinking maybe boost solenoid is caput? anyone else ever had a fauly like this? Please help if you can

Also at idle I get a very little miss I can hear and just see on the tacho, so going to do plugs etc aswell...............

Mmm, fuel regulator reference hose will definitely make it run lean. I eventually put cable ties around mine to stop this happening. Why did this make the boost sensor come up though?

Maybe because a decent amount of boost would bleed out of that pipe....?

No, not much, its only a 2.5mm hole. Perhaps it throws a code if theres not enough vac but I doubt it.

Just another M35 mystery then :unsure: .

      R34 Skyline climate control unit transistor

      That's not a transistor --- it's marked ZD1 which makes it a zener diode. As to what the breakdown voltage is, not enough there to divine.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Ethanol Content Sensor - Always at 11%?

      By joshuaho96 · Posted

      The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.

      It's almost certainly the same as the one next to it.

      Blue slip

      South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
