Engine flooded?
 

So I have Injen long tube CAI. Its been pouring and its not like I go seeking out puddles but it think I might have flooded my engine. It hesitates alot and does not sound to happy at all. What would you guys suggest? Thanks.

Park that bitch for a solid 2 or 3 days and then give it another shot. You do NOT want to run the engine if you've got anything in there and if you have really theres a decent chance damage has already been done.

I parked it in the garage, so i shouldnt run it to dry it off or warm it up or anything like that?

Do not run it. I'd suggest draining the oil out. Let it drain for an extended period if you can. Check the drainage and see if there's any water in it. Also, pull your air filters and see if they're wet. If the filters are wet, I'd replace them. It may cost a decent chunk, but it's a whole lot cheaper than engine damage.

I basically lost my 350 due to flood. Over a 3 month period of time, I had the engine replaced. One cat, one O2 sensor, BCM module along with a lot of major headaches. That's why I now have a 370.

If you have water in the engine, running WILL NOT dry it out. It will cause the engine to seize up.

Hopefully, the hesitation you're having is only due to water in the filters which could be causing the MAF to have issues.

When should I try to start it?

That does not make sense at all.
You definetly left something out of your story...
You probably drove into a huge puddle of water or something.
Leaving your car parked outside in the rain will not cause that.

I never said It was from being parked in the rain. It happend on my drive home from work, and no I made a point of it to miss all big puddles so I dont know what did it.

Hmmm, just let it run!
I'm sure you'll be fine do you notice your Z making loud noises when your shifting at high rpms?
If so, thats normal since that cai is sucking all that up.
Just drive low rpms on rainy days.
Any engine codes come up?

I'm sorry to hear that :(
But give it some time to dry out, the sensors might of picked up a little too much moisture and is throwing the ecu off . I know of some who have had this happen in heavy rain, and as it dries its fine. Keep it out deep puddles and it'll be fine. I've done driving in heavy rain also and have been pretty fortunate to make sure to avoid deep puddles. I'd suggest to let it sit? till the once in a century Rain Passes. :tiphat:

Have you tried to start it at all after you noticed the problem? I'm not suggesting that you start it now but if you have can you tell me what it did?

I had Injen intakes on mine and to me it felt like I had an over sensitive MAF.
I would leave it sitting out in the rain overnight and when I try to start it in the morning it just falls flat on its face. Took me a few tries before I got her started up again and when it would start I would be idling too high. (1000 rpms)
And no, it wasn't driven in a puddle (it wasn't even driven at all in the rain the last time it happened). This happened to me 3 times.
The filters pick up the moisture in the air and throws the car out of whack.

Not really. Over on MyG37, a few guys are having issues with the filters becoming very wet, just driving through normal rain... not huge, deep puddles. It's their location. Not ideal at all.

OP, let it sit for a few days... 2 minimum... and as suggested, drain out the oil and check for water in it.

I will try to start it in the morning and let you know. On a side note deslit Im pretty sure I saw you drive down commerce in tunjunga in the morning a while back. Also thanks everyone for the input I was completely clueless to the issue.:tup:

Were you parked there last week? I saw a black 370 there

Also if you live in tujunga I can probably stop by if you are throwing any CEL codes...I just got a unit that reads the codes.

yup that was me,before I added any mods.

might be wet filters, might have to drain the oil. I'd do that just to be safe...man and I told people there would be issues there and no one wanted to listen.

Just started my Z. It started fine on the first try but was idleing quite high. What should my next steps be?

Idling at 1000? Is your service light on?

I doubt he needs to check the oil. If enough water got into the engine to seep past the rings and into the oil pan, he would've hydrolocked the engine first.

on my way home from amplified i accidentally ran Rin into a humongous puddle...but she's still purring happily (weird exhaust location notwithstanding)

kinda weird how some injen users have issues, some (me?) don't? seems even more strange since my front bumper has a big ol' opening that provides water right onto the filters :rofl2:

Let it Idle till it warms up, and it should settle after a few minutes, also check the oil to make sure it looks normal

Lol your amuse kit must be creating a waterproof forcefield.:tup: My car seems to be running fine so far but I havent driven it.

That's Good to hear. :)

Goes
Back to what I said about the MAF. it sounds like it got wet and is "confused". Pull the air filters off and make sir they aren't soaked. If they are, bring them inside and let them dry out.

that's the surprising part though. i have brake ducts, a massive front opening, etc., so water gets in real easy. hasn't been a problem so far.

then again, i only drove it one day, it's boarded up in the garage right now.

Yeah, I don't doubt its not happening to everyone. The conditions have to be such that it causes problems, they may or may not happen, but the likelihood of them happening due to the location is greater.

Hey OP, everything good?

Yeah so far so good ive let it run a few times but only in the garage its pouring outside so I havent had a chance to see If I actually messed anything up. No lights are on and its starts well just still Idles a good bit above 1000.

Probably still picking up some moisture in the air. Mine would idle at around 1000 also.
I would leave it be for now and not start it till tomorrow when the rain is over and the car is fully dried out.
