SOURCE: idle lopping on 1992 honda Accord

its called a honda rev. its very easy to fix too. ok look at the intake manifold and there is a circular looking pipe coming up. unbolt one of the two screws all the way and the other one just enought to turn the top. once you get the top turned stick your finger in there its almost like a vaccuum and turn clock wise untill it stops and your done. it is only two phillips head screws and its sitting right on the intake manifold in the front of it

Testimonial: "Thank you! My sons first car now idles perfect. He is very happy to have it working correctly"

Hw can i fix toyota hilux d4d 3000,2006 model cannot rev over 1500 revs

There are alot of factors that could prevent the engine from revving over 1500RPM. Some sensors like the crank angle or cam angle have to be connected in order for the engine to even start, other wiring loom plugs like the turbo controller need to be connected or the car goes into limp mode and it won't rev past a certain point.

Then there are the automatic throttle controller area wiring loom type plugs near the inter cooler, sometimes people forget to put them all back and the engine won't rev high. Making sure the vacuum pipes in this area are all connected properly, one unplugged pipe, no vacuum, the injector pump relies on the vacuum system and if it doesn't work then not enough fuel delivery, engine can't rev high. Also if the fuel rail is leaking or if the fuel filter is clogged then engine won't rev high.

Engine revs up down while in idle

If its been without the line for over a year, I Highly doubt it. Look into IAC valve. Most are installed with 2 screws, easy to adjust. Idle Air Control Valve. Look that up, for a start.

My automatic Corolla AE110 vibrates when i stop in gear but it stops as soon as i start moving or when i put it in neutral.What can i do? Please help

It seems that your engine is tuned to very low idle revs, hitting the low resonant frequency of the car at tickover. When in neutral or revving up (moving), the engine stops shaking.
You can have it tuned to be slightly higher so it won't idle so bad, but you'll lose a little bit of fuel efficiency in the bargain.
Alternatively, just shift to neutral - free and easy.
