can a bad pcv valve make the car run rough
04 tribute is run rough at start up and sounds like a fan blade ticking coming from under intake manifold
Might be your engine valves, to an exhaust leak, to a misfire. Is the CEL on?
No lights on
That's the weird thing no engine check light has come on you would think their would be
Check engine lights and the OBD system are geared towards emissions related problems, and not for all engine/trans problems. There are a host of mechanical problems that will never show up as a DTC. I'd get it to a mechanic and see what is ticking. As to your question, yes a bad PCV or elbow can cause rough running/idle.
