So Tw my 2006 tacoma has 65,000 miles and i just replaced the second set of spark plugs at 60,000 miles.
So here is what i did for Sunday, went to the auto parts store and bought some non chlorinated brake cleaner and a really good throttle body cleaner.
First removed engine cover and removed 2 bolts holding air cleaner assembly and throttle by wire plug.
Next i removed the air flow sensor and cleaned it carefully with the non chlorinated brake cleaner and let it air dry on my kitchen table while i performed the next small service.
Ok, so here i removed the 4 bolts that hold the throttle body to the intake manifold so i could clean on both sides of the butterfly flap.
Let me tell you after 65,000 miles and a throttle body that has never been cleaned, man o man was the throttle body and intake dirty from air fuel mixture.
So next i cleaned the throttle body as perfect as i could with a clean rag and some throttle body cleaner. Keep in mind i cleaned both sides of the butterfly, something you cant do with the throttle body mounted. Then i got another rag and sprayed throttle cleaner directly on it and cleaned the inside of the intake the very best i could as far as my big hand would allow me too.
Finally i reassembled everything the same way it came apart.
TW keep in mind that i just replaced the plugs and oh my gosh i never realized how much power was lost with a dirty throttle body and probably gas mileage.
My uncle who owns a shop told me to do this and oh my goodness what a difference it made. Made my engine feel somewhat new again!!!
Simple service that can be done in about 20 minutes and makes a huge difference oh and if you do this be really careful with the air flow sensor( it costs a lot), and make sure to disconnect the positive battery terminal to kinda reset the computer and allow for adjustment.
Just some simple thought, try this and your truck should run a lot smoother and have some more pep or throttle response. Thanks Alex
