I gave it a tune up, replaced all the plugs and then I hooked it up 2 the machine and it threw a P0015 code for the camshaft sensor. I replaced the can shaft sensor now it's hesitant to start and when it does crank over it only wants 2 go maybe 2 MPH. It has no power at all. Please help.

Hi,

Did this just start since the tune-up? Is this the only code that was found? Have any new codes set since you have been trying to use the vehicle?

I attached a pic below. The code, P0015, is specific to the exhaust cam sensor indicating the timing is extremely retarded. In other words, it's running behind. Is this the sensor you replaced? Are you certain it is fully seated and connected?

Let me know. Also, if possible, record the engine cranking and running and upload it so I can hear it.

Take care,

Joe

Yes. It just started after the tune up. And after we replaced the camshaft sensor. Its hesitant in starting. It used 2 crank rite over, now it takes a good 3 seconds or so 2 start. And it idles like it's going to shut off. So I don't know where to start trouble shooting it. Should I start with the plugs or the sensor I replaced. I just don't know. It runs, just goes only like 2 MPH. It has absolutely no power.

Is it possible for you to record it running for me to hear?

Also, since you were working on it, make sure there are no engine vacuum leaks. It's easy to bump a hose and cause a leak. In addition, make sure the air intake tube (between the air filter box and throttle body) is attached and nothing is leaking there.

One other thought. By any chance were the wires for the coils mixed up and have you rescanned it to see if there are new codes?

Here is a link you may find helpful when checking for a vacuum leak:

One last thing. Make sure none of the sensors were left disconnected, specifically the mass air flow sensor which is on the air intake tube.

Let me know.
