I have a holden astra 2002. The car slows or loses

This answer was rated:

I have a holden astra 2002. The car slows or loses acceleration. It is now happening all the time. I have had it checked and I believe the throttle body has been cleaned and there is no error showing up on the computer. I'm looking to see if others have had this experience.
JA: How old is the transmission? Have you checked the fuel filters?
Customer: I have my car regularly serviced so the fuel filters would have been changed. My car is manual. Not sure what you mean by transmission - I'm no mechanic and not very car literate
JA: Are you fixing your Astra yourself? What have you tried so far?
Customer: No, I have mechanic. He has tested it on the computer 'thingy
JA: Anything else you want the mechanic to know before I connect you?
Customer: and no error is coming up. He has cleaned the throttle body.

It's a 2002 Holden Astra City manual

Hello there,

Astra is common for throttle body failure and ECM failure.

Strange you have no codes.

Check the brake lights function correctly.

The engine will give low power if the brake switch is on.

Could also be a fuel pump.

The brake switch has already been replaced. I've given your answer to my mechanic. However given the brake switch has already been replaced, he is now looking at the accelerator mechanism itself I think.
