Why Does My R33 Hate Air Con?!

Hey All,

I have a 1996 R33 Series 2 which hates having the air con running! I have noticed that whenever it is on the car seems to miss on idle, kind of feels/sounds like it runs on three cylinders for a brief second. When the air con is off idle is perfect and I have no issues. Does anyone know what might be the cause of this? I had an ac idle up valve problem in my GT4 so am wondering if this might be the cause?

Any advice on what to investigate would be greatly appreciated :) I do have broken manifold stud bolts which are being taken care of this weekend but not sure if that is contributing in anyway.

Thanks

Em

My 34 hates having the air-con running too. For some reason it effects the way my clutch engages? makes it

very difficult to shift and I also get the odd effect on my idle too, only drops rpm slightly but you can feel it stumble through the whole car.

I haven't got a clue whats wrong with it. The aircon is super cold and it still revs out okay.

Thanks guys! Cleaned the iac valve etc. Actually ran diagnostic codes and found out water temp sensor is faulty and for some reason the cold start valve wasnt even connected properly! Hopefully those things fixed will help at least! Haha weird isn't it re ur R34? Mine feels like it almost drops a cylinder occasionally on idle!

Hey Sparks, damn not yet! I actually cleaned my coolant temp sensor n the code went away- weird!! But it's still idling like ass now without air con :( haven't tried with air con tho! I assume worse lol. I did mess with the idle screw but it was shit before then. I'm wondering if throttle body or TPS maybe?

Hahaha ok well your Honda story makes me feel a bit better!

Sucks cos the car drives absolutely perfect otherwise :(

      What can't be done with a little bit of decking board or similar timber bolted to a hub flange via 2 wheel nuts is not worth talking about.

      R34 GTT idle problem

      By silviaz · Posted

      I noticed something. On the tps sensor and the sensor behind the adjustment screw is adjusted towards the far left. Are these screws supposed to be centered? (this sensor was in the same position before the tune as well)  Also attached a photo of where my car usually idles at when warm (sometimes a tiny bit above that). I think I might have screwed up the calculation and it might have better than I thought lol at 750rpm still not 650rpm though.

      So for both general interest of engine health, and to rule out any coolant/oil issues, I organised an oil analysis done on the 125,000klm oil Results below, all good, just a bit of fuel dilution which I'm not too worried about

      This is actually a really good way of measuring what wheels fit. If only there was a similar measurement between hub face and suspension :p That said, it's probably pretty simple to actually measure it all with the wheel off the car for the rear. The front is a bit more complex but..

      Being the top Google search result for R34 wheel-related inquiries, lemme throw down my experience. I calculated that 100mm from hub face to wheel face is about the perfect fitment for my ENR34 sedan.  I've been running 18x8.5s, ET35, with a 1" spacer. So, 8.5in to mm = 216mm. 216/2 = 108mm. 108-35 = 73mm. 73+ 25 (1" to mm) = 98mm.  If you wanna get close to this on dif widths, here are the offsets you'll want: 9" - ET around 15mm 9.5" - ET around 20mm 10" - you're crazy, but ET around 30mm All these should fit perfectly on a non-widebody, non-GTR Skyline. Note that it's probably the absolute max, and you're probably better off running a couple degrees of camber in this config, but it looks great, super flush.
