I posted a topic a few weeks ago about this problem but didn't get anywhere so I'm here again with some updates.

The problem is that my car developed a hesitation while cruising. No engine lights came on the first few times however after a while the SLIP light would come on & stay on (TCS turned off). Lately at times the engine light will also come on with the SLIP light.

Took it to a workshop who ran the ecu error codes and came up with the code for the AFM so I bought a brand new generic one and still have the same problem.

It's slowly getting worse & worse with it having a extremely tough idle on start up this morning then cutting out completely.

Ideas?

Engine light + SLIP is typically caused by busted coil packs. Next time they light up have a look at the ECU fault codes - the paperclip method is easy to follow. If you get 21 (ignition signal) it's 99% certain it's the coil packs. 50-60k they should still be good but you never know.

Here's a list of other things you can try: Resolved Misfire In R34 Gtt - Rb25det Neo Checklist and links to other misfire threads. Good luck.

Maybe it's as simple as a bad connection on the AFM plug. Or a faulty bit of wiring somewhere.

Some contact cleaner (or even WD40 works) sprayed inside both sides of the connection should make sure it's getting a nice clean electrical connection.

Good luck

      R34 Handbrake light saying ON and intermittently flashing

      Well, yes, every CU on the bus is available via the Consult port, but whether the scanner you are using is capable of talking to the TCU, the ABS/TCS modules, etc etc, is what is at question here. Many of them are only for engine codes. So, if you have one of those, you won't know if the ABS is having a bitch.

      Wheel Sizes & Offsets For Skylines

      That's now. R chassis Skylines come from a time when the tolerance in the ADRs was a bit more....slack. My car, on 235/35-17, which is damn near the exact same size as the original 205/55-16, is pretty much bang on correct indicated speed across the whole legal range. That's demonstrated with constant speed run over 5km, and GPS speed. It's just the luck of the draw. My particular speedo head has to be the thing that is "calibrated" that way, because everything else (the diff ratio, the gearbox and the speedo drive**) are all same same as most other Skylines. **OK, so the speedo drive is a Navara unit to drive the R32's cable, not the electronic unit than an R33/4 would normally have with teh same gear on it. Otherwise, I applaud your OCD tendencies, and I would do the same if I needed to.

      Not too sure, I believe the Nissan consult port does everything? Also just filled up the reservoir to full and the light is still on. The float seems to move up and down fine.

      The speedo's can be very conservative, when my Mazda NC MX5 speedo is showing 118kph, the GPS, and a calibrated radar.... cop mate.....hits me at around 110kph +/- 1 or 2 kph, and that is on a 215/45 17, stock tyres size is 205/45 17 as well, so weirdly conservative with stock tyre size When my Commodore speedo red 116kph GPS had me at 110kph on 255/40 17, so again conservative Google says manufacturers need to set the speedo from 4 to 10% slower than actual road speed.....for safety.....and compliance  After doing some offset and clearance measurements to see what can fit the NC on 17x8 +40, without guard rolling or rubbing anything at my current ride height, I've decided that when my tyres are toast, I'm going to fit 225/45 17 and see where that gets me IRT actual speed of my speedo and GPS/radar From the online calculator I should be still be doing around 5kph under an actual 110kph when the speedo is showing 110kph My ADHD requires that when I'm doing 110kph on the speedo, that the actual road speed is actually really close to that, and not alot slower And going from 205 to 225 still keeps the car within the %/mm allowable in the NSW vehicle rules and regulations, which is nice, as long as I'm looking at the latest version that is.....LOL https://www.nsw.gov.au/sites/default/files/2021-02/RMS-13.464-Light-vehicle-modifications-Vehicle-Standards-Information-No-6-November-2013.pdf

      Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.
