I'm thinking the temperature may have a big part in what's happening. Does this also happen when the weather is warmer? Maybe the fuel pump needs to be looked at.

Synth fluids all around may help too... tranny, diff., crankcase etc. May cost a little more in the beginning, but may also increase performance and fuel mileage too.

You have to also remember that you must sacrifice some gas mileage if you want some performance gains and vice-versa, nothing is free in this world.

You either have it or you don't, you can just "activate" it. Have you checked your owner's manual yet?

Try going over to Gadget's site at http://www.urdusa.com/ . He's got a lot of stuff there that may help your pinging. Many SC users have bought stuff from him and have been more than extremely satisfied. You may also want to check out http://www.tundrasolutions.com and ask the folks over there about your problem. Hope all this helps you out and keep us updated on your situation.

Most likely your brake pads/shoes are worn. Have a mechanic look at them, or you can do them yourself. Good luck!

Check the level of your brake fluid, it might be low. If so, fill it to the proper level. Also, if your fluid level is low it is also a sign that your brakes may need to be serviced. When was the last time they were serviced? Check your front pads and rear shoes. I bet one or both of them may need to be replaced.

Pushmatic - check out my post on another thread about the K&N below... http://us.toyotaownersclub.com//index.php?...&st=0#entry1907

It got gunked up with all the oil from the filter along with the dirt and dust that the K&N let through. I carefully cleaned the MAF with electrical contact cleaner, which you can get at any auto parts store. The link below will help you clean it the right way. Hope it helps. http://4x4wire.com/toyota/maintenance/taco...ntenancep5.html Just scroll down to the middle of the page.

The FIPK is a worthless piece of junk. Many have had their MAF (mass air flow) sensors fouled up because the oil from the filter gunked it all up. BTW, after a few thousand miles, check the intake tube that leads to the engine. I bet if you rubbed your fingers on the interior of the tube you will find that your fingers will be covered with fine layer of soot-like material. Why? It's the crappy K&N filter letting all the dirt and dust getting by and getting into your engine. How do I know this? Because it has happened to me. Should have saved your money and did the deckplate mod (link below) with the same effect and performance for almost nothing. As for the TB spacer, also a waste of $$$. Take a look at your intake plenum. I assume you have a 3.4L V6 engine. How is that swirled air supposed to make its way down to the combustion chamber? The air needs to go through those seperate openings and into the chamber while still being "swirled"? I think not. The spacer may work on carbed engines, but not on injected engines such as ours. To sum things up, both items are a waste of money.

5k should be OK if you do mostly highway driving. If you're in a lot of stop and go traffic then 3k would probably be a better choice.
