I have a 2002 dodge intrepid with 2.7,, we bought the car with a broken timing chain. had replace timing set and water pump.replace the whole timing components,, here is the problem,, it starts hard, but once running it runs find but you can't rev it up and you can't take off very fast in it, if you give it to much gas it like surges or cuts in an out,, if you floor it its like it dies and then drops down in low gear.. I get three codes p0344, p0016 and p0325,,, but I have replaced both cam and crank position sensors, but still get codes for them. I would appreciate any help I can get on figuring this out.
