I washed my car tonight and and i had just put on a air filter my cold air intake. i drove out fine and everything ran good for a little bit and my car deffinatly wasn't smokeing and the after letting it idle for 5 min. i drove off from a stop and my car just boggs out so i was thinking i might have sucked in some water. still no smoke. now my car doens't go past 4000 rpm's and it takes forever to even get to that. i changed my oil and cleaned everything i could. did i maybe bend a valve or something. anybody know whats up? gimme some ideas.
