Sure why not Mechanic's Assistant: What is the make/model/year of your car? 2015 Smart Fortwo Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far? I tried taking it to Mercedes and 400 bucks later still have the same problem Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Check engine light and loss of power if I stop, turn the car off and then restart it runs fine but the check engine stays on

Answer 1

Yea, alot of things can cause misfires on these engines (valves, carbon build up, etc) I have even seen the vvt solenoid cause a misfire on all 3 cylinders. So just the misfire code in and of itself doesn't say alot as to the issue. The fact that it resets like that and works fine for a period of time could mean the VVT solenoid is the issue, but looking at the solenoid readings and lruling out a fuel trim issue would be ideal when its happening. replacing he spark plugs was a lazy move on this vehicle unless they has reason to beleive they were the issue (excessive gap, very worn, etc)

Answer 2

its s timing control solenoid, but when it fails it usually throws cam / crank sensor codes.

Answer 3

i am here, sorry got pulled away

Answer 4

I understand the misfire codes (those are common) on these cars. The cars also go through plugs and have carbon build up alot quicker than most cars so fuel system treatment is helpful. The weird part with yours is you indicating it comes and goes, which sounds more like a fuel trim issue which can be evaluated on a scan tool just like the solenoid duty if it were stuck. as long as the snap on scanner has been updated past 2015 it should.

Answer 5

you want it to be running poorly when the mechanic is looking at it yes! Easiest way to diagnose it.

Answer 6

its tricky with no other codes then misfires yes. could try a fuel system cleaning to see if it helps, these commonly have carbon issues.
