Good colleagues! I would like you to help me. I have a 96 1.8cc Elantra which scan it and gives me the PO1614 code and PI1614. The car loses strength, jumps when it comes to an exit, accelerates very slow but does not smoke and this Gaston. I have changed the oxygen sensor (Lamda sensor), coland sensor, clean the MAF sensor, has high cables and new new air filter spark plugs. I no longer know what to do it disconnected the positive of the battery and the code is erased but just over 25 km the check light comes on and the failures begin! Thanks for the help.
