Hey I have a 2005 mustang with [camshaft](/topics-camshaft-ford/) position sensor code. I have replaced crankshaft sensor, camshaft position sensor, and the [alternator](/topics-alternator-ford/) (which is typically the cause on these cars). When I start the car I have to rev it to 1500 for a few seconds, I hear a knock and then it’ll run and drive great! Occasionally the car dies when driving and I throw it in neutral and carry on Mechanic's Assistant: Does the vehicle stall at low speeds? Does it sputter? Stall occasionally but not often Mechanic's Assistant: What is the make/model of your '05 car? Ford Mustang Coupe Mechanic's Assistant: Are you fixing your Mustang yourself? What have you tried so far? I do both my own work and shop work. camshaft position sensor code. I have replaced crankshaft sensor, camshaft position sensor, and the alternator (which is typically the cause on these cars). When I start the car I have to rev it to 1500 for a few seconds, I hear a knock and then it’ll run and drive great! Occasionally the car dies when driving and I throw it in neutral and carry on Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Nope that should be it!

What [engine](/topics-engine-ford/) does your 2005 Mustang have?

V6Single sensor

Where is the knocking noise coming from when you bring the rpms up? Front of engine? Rear of engine? Driver side? Passenger side? Lower part of engine?

it's not "knocking". I start the car, and I have to rev it or it will stall. I never rev it above 1500, and then there's what I call a "knock" the RPMs drop maybe 200, and then I'm on the road! It's coming from the engine bay I'm assuming. But it happends exactly the same every time.
Automotive Expert
I wonder if your timing chain cassette from the drivers side cylinder head has broken apart allowing the timing chain to be loose for that cylinder head. Since the cam sensor is on that cylinder head. Listen and check for the noise to be from the drivers side from of the engine.

You mean the rear timing chain guides?I feel like I hear the chain maybe when I'm inside the car but it's hard to tell because I have so much drone from my exhuast it rattles my change
Automotive Expert
The passenger side cylinder timing chain is in the rear of the engine. The drivers side timing chain is in the front of the engine on these 4.0L SOHC engines.

what do you recommend my next step is?
Automotive Expert
I would remove the drivers valve cover and inspect the timing chain and the timing chain cassette. Feel if the chain is loose.

Is any play at all acceptable? I can definitely do that.
Automotive Expert
No, the chain should be tight. Also use a flash light and inspect the timing chain guide/cassette assembly.

Can I also verify timing from the one side?
Automotive Expert
Not without the timing tools. This engine requires a special tool set to check the timing. There are NO timing marks.
