Hello everyone. I've been having an intermittent acceleration problem. I'll step on the gas and my car won't accelerate like it used to and then it will explode like a rocket. Sometimes it feels like the turbo or whatever isn't kicking in at all. The acceleration isn't constant. I'm thinking it's most likely a transmission issue or something to do with the turbo like the wastgate going out. Problem comes and goes. Any ideas? Car has 184k on it. Thanks.
