Hi Vlad

This sounds like fuel pump problem, or maybe even a fuel blockage in the filter, as what might be happening is when you trun over the car a small amount of fuel is getting through and then running out quickly and not keeping it running, so either the fuel pump has an intermittent fault and only runs for a short time and stops, or your fuel filter may be blocked and needs replacing, to find out if your fuel pump is ok, turn the key so the lights come on on dash but dont run it, go to the rear of the car and listen to see if you can hear a humming noise, what might be better to do is get someone to be at the back to listen as you turn the key, or get someone to turn the key while you listen, if you hear the pump hum, then that will be ok and then you might have to change the fuel filter. this is what it could be, however there may be other things involved, but that would be a good place to start.

Hope that helps

Check all belts pulleys could be injector prob

There is no one fix works on this O2 sensor code
P0170 - Fuel Trim Malfunction Bank 1
Possible causes- Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

whats also frustrating is what are you talking about --your not telling what problem is either resubmit or edit request

if it's rattle kind of noise , possible cause :VANOS or chain guide.
There many other causes , the noise must be heared
by mechanic , to identify the source.

Hi, there, Check your break pads. Could be from there.
cheers

There are a couple of relay switches in the side of the top on the driver's side. One of these is not working. Your break lights are out because of this too. You have to apply the brake to lower or raise the top.

If there is a code for the Air Mass Sensor I would recommend replacing it. Also a common problem is the intake cam sensor going bad and not giving a fault but will cause the car to stall.
