Old thread, but seems to be fitting for what I am presently experiencing. However, a definite fix does not seem to be in this thread.
Just made a move from Tx to Ok and all my tools and equipment are still in boxes somewhere. Can't put my hands on anything at present. I had to return to Wichita Falls and when I did, my car suddenly started hesitating as if I had bad gas of something. My plugs are not old and all the filter and oil was changed not that long ago. Low mileage on my 2010 Smart Passion since I did the original plug, filter and oil changes.
The car had the check engine light come on the day before this happened last. However, the code cleared easily and no problems until I did a longer drive. That is when the car suddenly started hesitation as if there was a fuel mixture problem happening. The car would not drive faster than 50 MPH and even then, if on a hill, it bogged down immediately. I could not press on the gas pedal and get the engine to rev high. The codes then showed up as P2177 and PO301.
Unfortunately, I had to have the car towed back home and, as I said above, no tools to do much of anything at present. May be a bit before I can locate my tools for my Smart, as well. Movers packed things and failed to list what box they were packed away in. It is like digging to China to find even a screwdriver. :-(
Any rate, I didn't want to cause more issues or potential damage, so the car is parked outside and not in use, presently.
I looked over the engine bay when all of this first happened to get a visual of any broken or pinched tubes or hoses there. I didn't notice anything. The engine was not hot and neither was the engine bay when the car started in doing this bucking or hesitation. I will be checking the spark plugs first if I can get to my tools and then the air filter for cleanliness. I don't see any Smart dealerships or repair centers near Ada, Oklahoma, so I'll be looking to find a local foreign repair shop that may have some experience with these cars if I can't resolve the issue.
Like say, this started up one day and then the car ran okay. I had just purchased gas in the morning and had driven maybe 150 miles with no problems noted before it started in doing this hesitation behavior. It did seem to clear after I slowed down, but within a few miles (maybe 20 or so) the car again just started hesitation and had no power at all.
In trying to decipher the codes and what others had found with these symptoms, this thread seemed to fit. It may take me a few days before I can really check out the spark plugs and coils, but just trying to find out if I am on track or not at determining what the main issue is. I know this is an old thread, but my internet access is severely limited at present as I await the local guy to come install the complete system here in our new home.
Any thoughts as to this issue and how bad or easy a fix it may be?
Thanks for any insight.
