Timing Help

[sandman]

I have just installed a new engine in my 2005 Rubicon and I am thinking I need help with the timing. I would like to know where the timing marks are set inside the distributor on a 2005 4.0 at TDC. The engine is running ok but when I give it some serious gas it stutters on me.

Thanks,
Steve

Ignition timing is not controlled by the Distributor on your engine. The crank sensor and Computer are responsible for that, and it is not adjustable.

Moving the distributor will affect fuel injection timing,as the sensor for that is inside the distributor. That adjustment is best set with a scan tool.

Are you sure of the year? I didn't think a 2005 had a distributor.

05 dont have distributors... it is COP, Coil over plug

I think it's a distributor, had marks inside it but not the old time points and the like . It is a 2005 but I put a stroked engine in it so what you are saying is that I need professional help? Is a scan tool similar to a code grabber?
Thanks for the information I am really in the dark as when I give it hard pedal it stutters like the dickens.

Thanks,
Steve

Then can someone please tell me what it is that's next to the oil filter, I am really getting confused and that's not to difficult with me.
Thanks..:confused:

What would look like a distributor on that engine is the oil pump drive and the cam position sensor. It is adjustable and needs to be adjusted with the aid of a scan tool. I have Tuesday off and can give you a hand with it if you want, shoot me a pm.

Hi there, I appreciate your taking the time to help me. I am not sure what is going to happen and if I can get to you but if it's ok with you I will stay in contact. I guess I have discovered that you need to rotate the inside of the housing we have talked about, I guess that it woud require a number of times to move "stuff" around until the proper position is found.
I sure am looking forward to being able to drive the new addition around.
Thanks and I look forward to talking to you again,
Steve

Yes, you are correct, you rotate the housing to adjust the cam sensor. If you can get it running you might even be able to get it close by adjusting it while running and test drive it, do this until it seems to run the best. You need the scan tool to really dial it in though. I'm always around so if you ever want a hand just let me know.

[sandman]

It is running but the check engine light is on. I was told a friend has a scanner and hopefully he has a bit more knowledge than I do. Would you rotate it while it's running like in the "Old Days"?
Thanks again for the help, nice to have folks around who are helpful.

This is where the necessity of a scan tool comes into play. The PCM can tell the difference in degrees between the cam and crank sensor. This data can be accessed with a good scan tool and you rotate the housing with the engine running to adjust this difference. It needs to be VERY close for the engine to run right, especially on a newer Jeep. Jeeps are notorious for running bad or having very weird intermittent driveability problems if the cam sensors aren't adjusted properly. Also when the timing chains wear that will affect the cam/crank sync and cause problems.

With the help of a code grabber and some luck I was able to get the code to vanish, it also helped when I plugged in a missed wire.. Is running well and just waiting to break it in.
Thanks for all the help,

it also helped when I plugged in a missed wire..

Always nice when it's something simple:) Glad you got it fixed!

[sandman]

Yes, simple but compounded by a brain fluff...
Thanks and thanks for all the help..

Maybe someday we can meet on a nice trail..:)
