Hey guys, gals. Looking for a little advice, knowledge. I just recently had my Head Gasket replaced by my local mechanic. Once receiving it back, I took it for a test drive. Everything seemed great except for when I press on the gas there is no "get up and go" like I usually have. It's like it lost all of it's power? Now once or twice, when first starting it up for the day, and driving, it would have normal "get up and go" for a few minutes then would do it all over again. Also SINCE getting it back from the mechanic the check engine light came on, the code was "P1383 Camshaft Position Timing over retarded (bank 1). I have taken it back to my mechanic, he's has had it for a week plus, taken it apart, checked the timing, SAYS timing seems right, but said compression seems low in the cylinders around 80 or so. Any knowledge that I can use from your experience to pass on to my mechanic would be GREATLY appreciated! Thanks in advance.
