Say when you pull up to stop light or sign and take off, engine boggs dwon until RPM's rev?
it only studders at low rpm it runs great at high rpm or accelerating only at idle and take off rpm
It depends on the RPM at Idle speed your low side apr.. 40 and High side at about 150 at 2000 RPM LOW 22 High 230 if high is over 250 there is to much 134A in system at a amibent temp. of 70 degrees F. RPM and outside temp effects readings.
In the context of the 1FZ-FE engine, "high pitch" typically refers to the sound frequency produced by the engine at a specific RPM, which in this case is approximately 400 RPM. At this low RPM, the pitch would generally be considered low rather than high, as engine sounds tend to increase in frequency (or pitch) with higher RPMs. If you are referring to a specific issue or characteristic at this RPM, additional context would be needed for a more precise explanation.
Nitrous really doesn't care at what rpm the engine is running at, whether it be low end or high end. Whatever amount of hp the nitrous is set to add, it will add at any rpm. Although, you need to be careful because you cant overload the engine at low rpm's or you'll start breaking things.
your tranmission is shot.
Yes, it is possible to have low RPM (revolutions per minute) at high speed, especially in vehicles with high gear ratios. For example, in a car traveling at highway speeds in a high gear, the engine runs at lower RPMs while maintaining speed. This is often done to improve fuel efficiency and reduce engine wear. Similarly, some electric motors can achieve high speeds with low RPM due to their design and the nature of their operation.
Not sure when you say low speed. Not knowing what your driveline ratio is I will just use some basic numbers .If 20 MPH is your speed and you were in first gear your engine RPM's would be 3000, if you were in second gear at 20MPH your engine RPM's would be 2500 , if you were in third gear at 20MPH your engine RPM's would be 2000. A difference of 1000 RPM's from low to high gear. Lower engine RPM's less fuel used.
Many things can cause lag while driving at a low RPM but not at a high RPM even if it is not the vacuum hose disconnected from the EGR valve as it could be the fuel filter. It can also be the park plugs.
My guess is its vacuum related. High vacuum at idle and low vacuum during acceleration is normal. Look for a vacuum leak
Low RPM. Gear is too high for travel speed
It will idle as low as 600 rpm.It will idle as low as 600 rpm.
The speed of a ceiling fan is typically measured in revolutions per minute (RPM). A typical ceiling fan may have speeds ranging from around 50 to 200 RPM on the low setting, and up to 200 to 300 RPM on the high setting.
