I was wondering if it was an issue with a sensor they replaced as the problem only started after they replaced the first two sensors. Is it common for a throttle position sensor to be playing up occasionally?

Any suggestions? Thanks

There is no longer any fault code. After they replaced the first 2 sensors the fault code went away but the low power issue came about.

Hi there, I have an automatic Subaru Legacy 2000. About 6 months ago I took it into the mechanic because the engine light was on - turns out it was because of the knock sensor and o2 sensor, they replaced both of them, the fuel consumption decreased a lot but then I started having low power issues. Around 1500 rpm the power would be dead and the car would crawl along until I put my foot flat down and then it would sort itself out after a few seconds and eventually take off. This doesn't only happen when turning a corner and accelerating but also if I'm going a speed where the revs drop to around 1500, then it'll often go sluggish and start losing speed until I push my foot quite far down again. I took it back into the mechanic who said it was the air flow meter (or sensor?) and they cleared it and it seemed to fix it but only for a week so they ended up replacing this too. This issue is now still there and they don't know what to do to fix it and neither do I... already spent far too much money - they assure me its none of the parts they replaced as they're all genuine new subaru parts. This issue is intermittent and seems to come and go randomly, will often disappear after driving for a good 10-15 mins. When the problem is happening often it smells a lot like burning when I get out and turn the car off. I have read a few other threads, some which mention the knock sensor and others say stop throwing money at the car and try cheaper fixes first. What should I do? Thanks
