Question about 2001 Pontiac Sunfire

Losing power and Grinding noise

I have two problems. My Sunfire loses power after take off. This happens after it has been driven for a while then is turned off. When I start it up and go it loses power and won't accelerate then it will kick in and go. It has died twice but starts right back up.

The other problem is a grinding scraping noise when the brakes are applied. I have brand new brake shoes and hubs on the rear and brand new rotors and pads on the front. There is no wear on them but when the brakes are applied there is this awful grinding scraping noise coming from the rear.

We can't figure out what is causing these problems

    When the car idles it makes a grinding noise but when I go down the high it runs smoother.

Why is my car sputtering and losing power after it warms up?

How long since a tune-up? Any applicable trouble codes? If temp related, check the coolant temp sensor. Check your throttle position sensor. Don't replace anything unless your testing points in that direction.

1999 Pontiac Montana 3.4L DTC P0300 Engine light came on and started losing power and making a noise

Well the code is a random miss rather than a specific cylinder.
The noise could be a cam or timing chain problem which would also cause running problems.

No power and losing oil on my 2004 isuzu kb300

check that the rings were installed correctly as they can only be fitted in one direction otherwise excessive oil consumption will result. Check float level or fuel settings for the slow acceleration on slope power problems .

Faulty Air Conditioning in a 2000 Nissan Pulsar N16

It's quite possible that your A/C compressor is locking up, thereby causing excessive load on the engine.(translates into lack of power to drive wheels) Typically there are signs, such as the noises you heard, or a slipping or thrown belt. If the compressor is locking up, being belt driven it will draw excess power from the engine. It's also possible that the compressor clutch in conjunction with compressor is going bad as well (both are usually related). That would cause excessive amperage to be drawn through the circuit, thereby blowing the fuse. Ultimately, it sounds like you have figured out your own problem, but I hope what I've posted helps.

Have you had the fuel pressure regulator checked? Also you might want to have the fuel pump relay checked.
