Last week my moms 1999 Kia Sportage failed a smog test. The smog tech said that at 2500rpm it was unstable which caused the test to be aborted. He felt that this was a warranty issue (7yr or 70K) Car has 51K.
Mom had to drive 130 miles round trip to a Kia dealer that could fix it.
They charged her $164 to De-carbonize the engine. Said that this was why the 2500 rpm was unstable. They also smogged it and according to them it passed.
I've never heard of a carbon problem in a newer car, especially one that does 4000rpm @65mph. I maintain this car regulary and see no reason for carbon unless it has bad valve stem seals. It uses no oil.
Also mom had 3/4 tank of gas upon arrivale at the stealer, When she left she had just over 1/2 tank. No extra miles though.
How do you remove carbon w/o engine disassembly?
So assuming that it had carbon somewhere how would this affect the 2500 rpm test.
I think that they may have faked a smog using another car, charged her for BS and sent her down the road.
I was assuming that it had a faulty sensor or other computer problems and never would have guessed carbon.
