I was playing around with my intake earlier, i didnt disconnect anything electircal or mechanical. my idea didnt work and i took the parts back to the store. while i was driving, i started to feel the car kick a lil while i was at a stoplight. the revs ranged from 450-900, im used to it sitting at a steady 600 or 550. i thought it may be a problem with the gas, so i sped off of the line and gave it a nice healthy dose. well that stoped the problem for about two stoplights, then it started again. i know it isnt injectors i had that checked about two weeks ago.

any ideas, im wondering if i damaged my maf.
