has anyone had a failed:

MAF sensor
Lamba sensor
CO sensor
Coolant sensor

if so please explain how car was running before fixing problem.
trying to diagnose my problem, i have done several ECU checks and apparently everything is fine.

car wont run between 1.5rpm and 3rpm when cold. when i push the accelaretor to any amount under 3rpm then it struggles and shakes and sounds really bad. anything over is ok and when driving it will kangaroo around until warmed up.

hot or cold when i nail it over 4rpm then the boost seems to surge on and off.



just wanted to know if anyone has had any of the above things fail and wether they were anything like what i have.

 

not the lambda/co2 sensor in my book
....suspect the MAF?

 

Coolant sensors usually show signs of fault when the engine is warm. Hot engine being overfuelled etc.

Do these cars have a throttle position switch?
