Hi all-

I've been working on this problem for a while. Before the code was thrown, I had engine RPM bouncing and jerky during acceleration. I replaced the spark plugs, but it didn't get any better.

It finally got bad enough to throw the P0011 Intake Camshaft Position Timing - Over-Advanced (Bank 1) and P0300 Random Misfire Detected codes.

After some research, I replaced the bank 1 Intake Timing Control Solenoid and cleared the codes. It does run better, but still feels a little off and RPM's aren't as smooth as they should be.

I checked the cam position sensors, and crank position sensor according to the service manual, and they checked out fine. This isn't an extremely consistent problem. Do sensors start to fail, or just fail all at once?

Also developed at the same time is a squeel from the front of the engine. I replaced the idler pulley, but it's still there. I assume it's either water pump, alternator, or tensioner. Has anyone experienced this?

Thanks
