first of all i have a 07 cobalt ss s/c and the last time it rained i accidently sucked up some water and the mass air flow sensor got wet well i let the car sit and after about a day it drove fine...this time it rained i didnt drive through water my car sat in the parking lot at work and some how it got wet again and to drive it i have to gas the crap out of it just to keep it alive...i guess my question is could it be that my maf sensor is messed up from the first time or what....how could it possibly get wet from just sitting there? any ideas would be helpful thanks

 

More than likely it's your maf,i have an extra one i might sell if thats the problem.

 

First of all either ditch the intake, get a Hydroshield, or seal the area off better if its a stock intake. I would try pulling the MAF and spraying it with electronics cleaner, it sounds like you may have a fried MAF, as they tend to just jerk the car around uncontrollably if they're simply wet..

 

ok just checking my dad is a mechanic and he said he wants to look at it some more but i might be interested in the maf if he comes to that conclusion too

 

What are your mods?

 

well i just bought the car and it has stage 2 pulley and some sort of exhaust i think just a muffler the rest of the exhaust looks stock...i recently bought a stock pulley to replace the stage 2 but thats it or at least that i know of

 

Clean the MAF with Throttle Body or Carb Cleaner....Then use Expandable Foam that you use for insulating houses ( You can get at Home Depo or Lowes ) and seal up any holes that let water in around the splash sheild that goes around the intake from the bottom to the wheel well.

 

just put a hydro shield on it. i had the same problem. put the sheild on and call it a day

 

alright thanks for all of your help

 

what intake do you have? I know with my fujita i get a cel from driving in the rain and cant go half throttle when is wet out....

 

with my fuhita i cant give it 1/4 throttle without it starting to mess up. until i put the sheild on now i have full powa when its raining
