Hi, I'm driving a 2007 Nissan lafesta with 175,000 kms. The airbag light has come on and won't go away after trying to reset it. Now it also has a deaccelation problem. You put you foot on the accelerator, you can sometimes have a problem that it will drive as slow as a snail and you can only go 30 or 40 kms per hour. No automatic transmission fluid change don't since bought 7 years ago at 75,000 kms from Japan. No transmission problems at this stage.
Well many things can cause that but the most common are either weak fuel pump or a clogged catalytic converter. You can pressure test both to see if the cat is plugged up or if the fuel pump it doesn't put out enough pressure I would start there
Check your air filter as well. If it was never changed and is completely clogged up it can cause that as well. I've come across a few cars like that over the years.
