engine clicks on start-up
First, the good news...
I cleaned the throttle body & MAF this weekend and JEEZUS! I cannot believe the difference it made in the performance. Everything runs so much smoother and I have even noticed an increase in acceleration. I am NEVER going to ignore that cleaning again! Thanks to everyone for their insightful posts & comments!
Now, the bad news...
With the colder morning temperatures, I have begun noticing that my engine makes 4 rapid clicks on startup. (kinda of a tck-tck, tck, tck pattern with a slight pause after the second & third clicks) I am thinking this could be the oil drain down because of the filter. I am due for an oil change so I will see if that will help. I noticed the sound during the cold startups the past couple of years and didn't think twice about it until I read the posts here. What would be my next steps in fixing this if the new filter doesn't help? Thanks!

I followed the process as described on the discussion forums.

I used a teflon safe air intake / throttle body cleaner spray followed by a blow-out with compressed air. I only sprayed a little TB cleaner at a time and then dried it.
For clarification, the ticking noise has also happened in past years during cold startups... not just since I cleaned the TB.

Thanks Ken, I will get the oil changed this weekend. My time is already budgeted until then.
I don't know if the noise is "worse" if the truck sits a long time without starting, it is just more likely to occur. The noise is most common during morning startups in colder weather.

The oil & filter has been changed with no improvement. I have found that if I let the truck sit for about 30 seconds with the key in the "On" position before starting it, the noise doesn't occur. I discovered this after getting into my truck one morning and trying to get organized before starting. I had the key in the on position while I was arranging my junk and when I started the truck... no clicking noise. I made sure and tested the scenario several times to be sure it wasn't a fluke and it really does alleviate the noise. Anyone have a clue what could be the cause? Leaving the key in the "On" position is just a patch, I would like to know what the problem is so it can be fixed. Thanks!

Thats a wierd one, are you sure it's coming from the engine. I would get some else to start it to make sure it's not coming from another location.

Very strange indeed, that just affects the fuel delivery. Get someone else to start the truck and use a screwdriver as a stethoscope and touch the various parts of the engine, both heads, front, accessories, etc, and see if you can pinpoint the noise. Caution the fan and moving parts. I know you don't have much time, but this will help.
