Dropping Revs When Holding Constant Throttle

Hi Guys,

Got a little problem i can't seem to figure out why, I've tried to search around but i cant seem to find why this is happening.

When i hold the throttle down to a constant position (any position) e.g 2,000rpm, the car drops revs, as if it is about to turn off but then goes up again, not that dramatic but it drops from 2,000 to about 1,800rpm for a second or two and then goes back up, and keeps repeating, tried it at higher revs e.g. 5,000rpm, still the same thing.

happens alot when im driving too, because of holding the throttle in 1 position. even if its at 50km\80km\120km. However, if i push the throttle all the way down or 3/4 it does not jerk\drop revs.

Engine light is not on.
Doesn't seem to be fuel, because when i push the throttle all the way down it should happen during that period.


anyone have any idea of what it could be?


Regards,
Nick.

Replaced sparkplugs and coilpacks, and no, it's manual.

any other ideas? Saw something online about TPS could it be that by any chance?

TPS is definetly a likely possibility, could be something as simple as a dirty throttle body. Do you have any way of checking your car for error codes?

I'll have a look at the throttle body tomorrow, I might be able to have access to an automotive shed that has a snap on, but i dont think it has the right key(chip) that i need.

      Nice one, I'd argue that the white S1 RS260 is certainly the best looking of the Stageas. And yes, fully agree on the forum situation. It's a bit of a shame, but at least SAU is a good place to be. I found the facebook groups to give me FOMO because people were trying to one-up each other and show off in some way. Feels much more natural here. There are people with seriously nice builds, but I can appreciate it rather than it making me question my life choices. Might be that people are more open with sharing how much work/money/suffering it takes to actually get there.

      Evening, wanted to pop in and finally register to say hi to everyone here on SAU!   It's been a while since I've been active on a forum, but back in the day I used to be relatively active on ClubLexus and other hobby-related forums. I'm glad to see SAU is still around, since with the advent of Facebook and Discord it seems forums aren't what they once were. As a recent new owner of an S1 260RS Stagea, I've found so many older guides and helpful tips from SAU that I figured I needed to join and say a grave thank you. My recent acquisition has only become legal in the US for the past year, and knowing that similar car enthusiasts from across the pond have already figured out the kinks and tricks to get these 25+ year old cars running well. I look forward to diving into more of the SAU forums as well as hopefully contribute some info myself for future posterity.   As a pic tax, here is one of the few good photos I have of my Stagea. I hope to get way more in the future!

      Is this where I say "Hey man my airbox cost me horsepower in my Naturally Aspirated Engine"? (I know you need them for legality in NSW)

      1.5mm alloy folded up, it will need a tweek, as the angled bend only got to around 45° as that was the max that the break press would get with the other bends, and I needed a fair bit more, but and the alloy is easy to bend too my will by hand once I trim the lower section out I'll Dremel out and form the angle and mounting point on the lower section when time permits  As for the lid, I'm looking at going a "cap", instead of a flat lid to hide the fixtures a bit
