I've been putting more miles than usual on my car lately, due to a seasonal job. 80 miles roundtrip, stop and go traffic.
The other night on my way home from work my 2013 Gas Smart Fortwo (35k miles), check engine light came on while driving on the freeway. My car immediately lost acceleration and the gas pedal was useless. Luckily I was able to pull over to the side of the road and call AAA.
I ran a code reader and the codes P0300, P0302, and P0303 popped up. AKA - Cylinder 1 - 3 misfires. And then finally P050B - which I think also relates to the cylinder misfires?
I called a mechanic friend in the morning and he told me it was probably my ignition coils. I told him that I replaced my spark plugs about 5K miles ago, (at 30K miles), but not my coils. He told me he believes my spark plugs malfunctioned and now my coils have to be replaced too. That they should always be replaced together.
He recommended I go with dealership coils, but after getting a quote from Mercedes for $1000 for 3 coils, I knew my wallet wasn't going to let that happen. Instead I found the High Performance pack from Smart Madness for $200 for all 3.
Has anyone had this problem before? He doesn't usually work on Smarts, so I wanted to get a second opinion before I buy new coils and spark plugs. Also, are the Smart Madness coils any good?
Not sure if this is worth mentioning, but based on a few other threads I read - I did fill up my car with $15 worth of gas that day. I drove to work 40 miles with no problem, and then on the way back home, after driving 20 miles is when the engine light turned on. Bad gas? It was from Shell. I always use that station and put 91 gas in.
Thanks!
