I won't bother with that right now.
I just got back from Mr. Lube, I got them to do a Tranny flush, Rad Flush and Fuel System Clean. The top end cleaner had my car smoking for about 15 mins. I took it for a few runs off and on, my fuel mileage went way up and the car has it'* hard pull again.
I also had them put in a Cabin air filter as we all discovered that mine didn't have one. SOB'*!
But all the servicing made up for my Hot air intake which is probably taking in luke warm air. Come spring-summer when I have enough money I'll buy a real CAI and start the modding.
