k guys my car is not functioning well, as water went through the hood vent and into the engine..my evo wont go pass 2500 rpm and wont go past 20 mph..i checked and changed spark plugs and MAF ...im all out of ideas can anybody plzzzz help me out asap...would it be a leak somwhere ??? plz help!!

 

what? It is true that water gets through but it shouldn't cause any damage. Once the manifold and turbo get hot enough (within 10 seconds of turning the car on) it creats steam. Unless water went into your spark plug holes and into the engine verses on the engine which is pretty much impossible with the cover and boots and wires...Even if it went through the air filter I don't think your car would even start since water doesn't compress well. Free bump for you.

 

I dont think the water did anything to it. you have another problem.

 

That's weird usually water eveaporates right up when it reaches inside the engine bay.

Is it making any noise?

Did you check all the IC piping to make sure you haven't blown any of them off?

 

any cel/ses codes/lights pop up? open up the hood and see if there is anyting you need to dry off...

 

how did the water get in..........I.E. did you go through a big puddle and water came in, or was it just raining and rain got inside............explain

 

Going to need more information. What is the car doing when it hits 2500rpms? Sound like a rev limiter or studder? Are you getting a CEL?

for a start check all of your wiring connections (ex. spark plug, MAF sensor, etc....) As the OP said how did water get under the hood?

 

i would check the IC pipes

 

^+1

 

yup IC pipes i would say, from the intercooler to the engine block, check all couplers. My friends brand new Evo 9 MR's Coupler that connects the upper IC pipe to the engine block popped off, and his car wouldn't go above 2000-3000 RPMS nor more than 20mph

 

^^what all of them said...i had a hose blow off my APS bov. It was so loud and my car would not run right, rpms staying at 2000rpm and then the car shut off.

 

^^^ yup happened to me twice before. i installed my injen intake and intercooler pipes and i didnt clamp the coupler for the UICP tight enough and it popped off. my car wouldn't go over 20 mph. happened again when i didnt tighten the coupler on my BOV.

 

yea same thing happened to me when my uicp blew off the intake manifold.

 

jeez.........and this is a good reason to leave the rain guards off in the front in case something like this happens on the IC side on the side of the road.........
