I bought a 2004 dodge neon srt4 about a year ago. I just took it in for a full tune up and got it back with a ticking noise in the head, you can hear it from inside the car when you start it and driving. Also when its in first and second gear when I accelerate its kind of lumpy or the car shakes in low rpm ( im not sure how to describe it) I don't know if these two issues are related to one another but they both started happening right after I got the full tune up on it. any info will help?
