hesatating or viabrating not enuff to tell which
 

Not everytime I pull of but sometimes I feel a small viabrating feeling very small there is nothing coming up on the scanier. Last week I had an p0103 code pop up but I dont think they are connected. Its been a little while since I changed my fuel filter. I am certain that this is is something stupid but I just cant put my finger on it. I cleaned the MAF with a special cleaner made just for that and the code went away! And I put a new air filter in, and may have gotten alittle carried away with the carb cleaner but what could this be. Thanx in advance for any thought"s
