My throttlebody and intake had a lot of buidup the return line in the intake tube from filter had oil in it they say its normal for direct injection but anyways there was build up carbon. My acceleration was poor in park for ex. I would accelerate and my foot would be going down with the gas pedal and nithing would happen then suddenly bamm it will ram up to2k -3k rpms now after the cleaning the rpms do respond with the pedal. And when starting from a stop I would notice the enclave felt heavy then suddenly at about 25-30 it would feel much better this was before cleaning now it feels better from start. I bought this enclave not long ago and now it has 68k miles.
