In general, a faulty TPS will cause your car to buck and hesistate. It'll feel like a slight misfire. If you have an automatic trans, it will not shift correctly. You can check TPS voltages by following the diagnostics steps in the FSM.

i found with my tps when it played up the warning light would show

so usually i would get out unplug and replug it in

i found the problem to be the loom being on to tight a turn from the tps and causing bad connections in the plug so i moved the loom slightly tighten the pins in the tps and it hasnt played up since so it might be worth trying that first

You can adjust it by moving it up and down on the throttle body while it's lightly screwed on. Doing this can help to iron out a few probs including idle probs etc.

And no i'm pretty sure from memory it is solid plastic and can't be opened. Try adjusting it

Cheers

you can't just adjust the TPS randomly. there's a specific voltage u have to get at idle for them to work correctly. if u adjust them too far then the computer would never enter the idle map or other end it will never enter WOT map.

    • Just don't use ChatGPT or any other artificial stupidity for the equivalent of googling. Their demonstrated inability to discriminate reality from hallucination should be enough to make them totally untrusted. LLMs don't know anything and cannot think to even the smallest extent. They are just predictors of the next word, and that should never be confused with capability.
    • I think, given the usage model described in the OP, I'd never ever experience the wonders of the 400kW upgrade. What I really need is boost from 2000rpm and probably no more than 260-270rwkW. But I suspect that the highflow is not actually the turbo for that purpose, so I may in fact need to get a G25 or 30 or something right sized and very spooly. We shall see after it is tuned. I've had to back the boost and boost ramp off to stop the thing from pinging since the highflow went on, so I've been almost living the NA life for 9 months now! Injectors are recently in hand. AFM is in hand. Dyno is fixed. Just need to clear a queue of f**king Supras out of the way (and probably fit my new gearbox). So....some time this year? Lol.
    • For what I gather is a Sunday/summer car....braided is fine. You're not going to be left without a vehicle and you have plenty of time for inspection/maintenance. Oof. I wouldn't use them that way. They can probably handle the temperature** but the internal corrugations means that their flow characteristics are a bit shit. Lots of extra friction and pressure loss. Makes them flow like the next pipe size down. ** They are stainless, and the stainless can usually be at least something like 304L, which is pretty good at higher temperatures (unlike 316L, which I would use for a wrt/corrosive environment, but not a particularly hot environment). But the welding needs to be top notch. And even then, because you usually need at least one cone-seat end on them (because you can twist the hose and do up both ends at the same time unless one of them is a union) they can be prone to coming loose with heat cycles.
    • I don't have the OEM oil feed lines though and the turbo-wraparound line is torn, only has water. My plan is to get replacements for these and just connect a braided line to there. And make sure it's leak free. Hoses like these are also sometimes used to connect external wastegates, so for an EGR I think you're good using them.
    • Alright I understand. The most likely case is probably gonna be that I just keep the OEM unit in the car as long as it works.
