1kzte hilux 04

1kzte intermediat throttle response, was dyno tuned a few years ago, still makes same power/torque but now drops off as soon as it makes power, sometimes when driving it looses all throttle input untill you take foot off acelerator and back on, then ok... some times eng light comes on and goes into limp mode for 30sec then ok again. codes showed vac control on inj pump, replaced, no change. im thinking tps switchs, any ideas??

You have rust particles in the float bowl. The easiest thing to do is remove the side cover of the carb (the thing that unbolts, with a sight-glass on it) and spray carb cleaner into the float bowl until it is clean.

SOURCE: Zero throttle response and sluggish accelertation

Wow, great description...I suspect the catalyst is bad...(in the exhaust) but try this cheap fix.
go to Advance Auto Parts and buy a can of "SeaFoam" ($8) and following the directions add to fuel and drive for at least 100 miles...see if that helps...if not, have a mechanic look at the catalytic convertor/exhaust
Good Luck

This problem does not seem to be the fuel pump. it appears to be an electrical problem in particular your ignition. Also check the MAF (Mass Air Flow) sensor. if the computer cannot read how much air is coming in it will try to shut down.

SOURCE: 2003 Toyota Corolla oil pressure light flickers

see if you have any oil level or pressure sensors. sometimes these can get gunked up. You may need a new oil pump. I suggest you start using a senthetic oil (valvoline,mobil 1 is reccomended) after u get the problem fixed.

Turbo boost adjustment for mack 470h.p. engine, how do you make this adjustment?

there is none as the engine uses all the boost it can get
if you want more power then have the pump reset to 500 hp settings
boost pressures are a result of the fuel settings from the pump allowing more fuel in to burn which produces a hotter exhaust making the turbine wheel spin faster which creates the extra boost
a genuine mack 470 hp engine is a really torque engine if driven properly and if dyno tested will produce around 450 hp at the back wheels with a relative flat torque curve which means that the rpms hang on longer before having to change gears
however to keep the maximum torque available at rpms you have to drop a half ratio as soon as the rpms start to drop as the range change will be 250 rpms and that will keep the torque range well up
don't let it bog down as all that does is waste fuel and drive time

What causes my truck to idle when ac is on

What is year--make--model? How long since a tune-up? Any applicable trouble codes? Around here, some of the national brand auto stores will check codes for free.

If no throttle response, have to check proper fuel pressure and injector pulse. You can check throttle linkage and any throttle-body sensors.

My injector nozzles for Toyota Hilux 2.5 is loose I need to now if they need to be torqued and with how much

no year? lots of years, no? and lots of 2.5L no>? why not learn what engine you have, 2M? diesel 2J? , 2AR? , 1JZ, 2VZ , 4VZ,2MZ
3gr, 5GR. we can not guess engines. not now , not ever.
what year, what engine, gas or diesel.
that is the first when taking cars, after all even Toyota parts
guy says the same thing,for same reasons.
or post the VIN.

new seals are for sure needed log and and read, its there.

torque varies by engine,

2005 Ford Explorer V6 goes into fail safe mode with wrench

It should be noted that the ETC system includes a warning indicator (wrench light) on the instrument cluster that illuminates when a fault is detected. Faults are accompanied by DTCs and may also illuminate the malfunction indicator lamp (MIL).
Torque Based Electronic Throttle Control (ETC)
The Generation II (Gen II) torque based electronic throttle control (ETC) is a hardware and software strategy that delivers an engine output torque (via throttle angle) based on driver demand (pedal position). It uses an electronic throttle body, the PCM, and an accelerator pedal assembly to control the throttle opening and engine torque. The ETC system replaces the standard cable operated accelerator pedal, idle air control (IAC) valve, 3-wire throttle position sensor (TPS), and mechanical throttle body.
Torque based ETC enables aggressive automatic transmission shift schedules (earlier upshifts and later downshifts). This is possible by adjusting the throttle angle to achieve the same wheel torque during shifts, and by calculating this desired torque, the system prevents engine lugging (low RPM and low manifold vacuum) while still delivering the performance and torque requested by the driver. It also enables many fuel economy/emission improvement technologies such as variable cam timing (VCT) (deliver same torque during transitions).
Torque based ETC also results in less intrusive vehicle and engine speed limiting, along with smoother traction control.
Other benefits of ETC are:
  • Eliminate cruise control actuators.
  • Eliminate idle air control (IAC) valve.
  • Better airflow range.
  • Packaging (no cable).
  • More responsive powertrain at altitude and improved shift quality.
  • DO you know what electronic throttle control is ?

Low lever rpm rate is hight(8)

The relation between torque, power and angular speed is


Power falls off below a peak located at high engine speed, because less fuel/air (energy source) is brought in and burned per second. If that were the only factor, then power output would be proportional to angular speed


and torque would remain constant down to idle. In fact passenger car engines have a fairly broad and flat torque curve.However engine efficiency drops with at low speeds since combustion chamber shape, bore/stroke ratio, manifold runner shape and length, valve lift and intake/exhaust valve overlap, to name just a few factors, are tuned for best performance at higher engine speeds. Thus torque eventually falls. In racing cars, the tuning is "peakier," that is, they produce far more peak power but only over a narrow RPM range. As you might expect, the torque curve isn't as flat in this case, and it falls off more rapidly. Vehicles that are optimized for very high torque at very low vehicle speed either have no high end to speak of (road graders, bulldozers) or, if they need both, use different systems (diesel-electric locomotives

HP increase at elevation using a Dyno Jet Dyno?

same dyno? same operator? theres something wrong. the lower altitude the better, as far as I know. But someone thats smarter than me and has high altitude /dyno experience would be better to answer the question.

Need more horsepower

You can get a Dyno tune done at a speed shop. Drive down to the local speed shop and they would know the best guy's in town to Dyno tune your engine.
You can work with the tech to tune your toyota the way you want it to perform. Can change the shift points to the transmission, RPM limit, and speed limit too. 
Going to keep it simple so do the K&N filter, good spark plugs and wire, and Dyno tune. 
Good luck and keep me posted. be glad to answer more questions
