Default Leak...?

i think i might have a leak somewhere...

here is my situation: i drive and shift from 1st to 2nd and when i give it a lil gas it bogs, like it does when ur in 5th gear and ur not going fast enough. well i shifted into 3rd and it did the same thing. what is wrong with my car??

Also i just orderd some 4.10's and a speed cal!

Yippie!!

+1 Check all of these and it should stop, this reminds me that I need to clean my air filter!

No check engine light is on, any other ways to do this in a mass search. not like spending 5hrs guessing here and there.

Check the maf, tps, and air filter first. It's probably one of those, kinda hard to diagnose over the web.

id check the fuel injectors, it sounds like youre either not getting fuel or air. id start with the air filter, then the fuel injectors, then the plugs and fuel filter. if its not any of that, try to listen for a vacuum leak, could be losing compression.. the possibilities are endless, lets hope its a cheap and easy fix

ya i kno it hope its really easy, i just orderd my gears lastnight and got to save up again for the install part. If its at the air filter, would that just be a bad one, or is it leaking? and what could be wrong with the MAF or tps?
