I haven't posted in a while, but here's the last months activity.

- I installed a Dinan intake filter and crafted a heat shield for it out of a piece of an airbox from a f150 I used to have. Air intake temps run between 75-110°F now. Stock was 105-145. Intake without heat shield was 115-160.

-I replaced my alternator that went out suddenly and replaced my serpentine belts. I also replaced the hose clamps on the power steering reservoir lines that leaked and caused the alternator to fail.

-I replaced the expansion tank that started leaking and transmission thermostat that breaks when you take out the expansion tank.

- I found and fixed a vacuum leak that was causing me lean CEL codes. It was a loose hose on the side of the intake boot. I also identified the cause of my rich code to be a bad cat. I'm going to end up replacing them with catless headers with a test pipe only. A guy will buy the cats for $50/ea and the headers will cost me ~$100. Free upgrade sincr I don't have emissions anymore it's worth it. Just got to get some spark plug defoulers to keep the O2 sensors happy.
