Question Timing belt change - Low idle rough idle

I have replaced the timing belt today and made super sure about getting all of the timing marks lined up correctly. Put it all back together and the car runs fine but it seems to have a rough intermitting idle, about every 5-8 seconds it rough idle's. The car does run fine through the gears and have had it up to 65mph, with no issues, Also No codes come up.

Any suggestions?

I thought you needed a special locking tool due to the variable valve timing. That is, you can't just take the belt off and line things back up properly afterward. But I have to admit that the exact workings of VVT still have me a bit mystified and I'm not brave enough yet to attempt a timing belt change myself.

maybe something got unplugged, or disconected in the process, probally a simple item, get a good light and take a good look, I am master certified and yet I put a training wheel on my grandsons bike today and the wheel fell off! he was good about it though, he promised not to tell my wife if I threw in a bulb type horn and streamers!. bless his heart!

I would recheck all the connections like said above.

No you can do the job without locking the cams. You can mark the pulley to the cam cover before removing the belt if it worries you.
It is basically just as easy as a Non-VVT belt to do.

I think I'll use the cam locking tool anyways. I figure they must have invented it for a reason.

But I suppose if that was the OP's prob he'd have a check engine light... so I won't take the thread OT.

Replaced the #3 cylinder coil pack and that solved my misfire problem on the #3 cylinder code P0303. I found out through the web site that the cylinders are numbered 1-6 starting with #1 cylinder at the timing belt. I did get mixed up between the firing order and the cylinder order.

Thanks for all the help. Car purrs like a kitten and runs like a scalded dog.
