What could be wrong with my Toyota Echo if the engine chugs while idling, and the car loses power when accelerating (stalling out if accelerating too quickly)?


There are numerous things that will cause this problem. If the check engine light is on, have the codes checked to see if there is a problem the computer has found to cause this issue. Even without the check engine light on, there may be a code stored. You can also do a visual inspection under the hood for any disconnected hoses causing vacuum leaks. These are the best places to begin with diagnostics

Engine revs high in park & neutral


you could have a vacum leak some where in the system that can cause high rpm,also if you have a bad tps(throttle position sensor) it can cause this type of problem.you don`t say if you have check to see what is turning on the check engine light and what code is in the computer.this should have been done and may have help to find the problem in the begining.

My car accelerates on its own while i am driving and does it in any gear. I am not sure what is causing this so any help would be greatly appreciated.


Thinking the top motor mounts ?
Open the hood,so you can see the top of the engine while sitting
in the drivers seat,start the engine,put it in drive ,while watching,
then neutral,then reverse,if the engine moves more than about 2
inches there is a bad mount,makes the throttle cable pull.

Sluggish acceleration. High RPM, High Oil Pressure


I hope I'm wrong but I think your torque converter is failing. Sorry, Gary

Blazer not responding to the accelerator, won't rev up


I'm actually going through the same thing, after i just had my fuel pump replaced. Mine turned out to be my Mass Air Flow sensor (MAF) which when not working properly has the same effects as your acceleration not working.
