Engine bogging after flood.. lost?

[mitecl96]

I will start off that about 2 weeks ago we got a lot of rain Saturday and when I was heading home that night. I ended up going through 2 different foot deep water puddles flooding my interior. (Glad I have no carpet).

I noticed that next day I started my car and after a min of it started it almost wanted to die. It idle high than went to normal with no problems. Than leaving Walmart it did the same thing this time the motor was hot.

So I decided to look at the start plugs and check the gap. The tips where a little white. Than when I checked the gap it was .045 and I was told they needed to be .035 so I fixed the gap. This time when I started it it didn't want to almost die it just started idling rough. Than I noticed when I go to leave and shift to 2 it bogs down and no power. But only after start up. Than runs fine.

Till 2 days ago it started to randomly bog down half the day than stopped.

I've been searching found boost leak and stuff like that nothing really for a 420a besides maybe vapor lock in the gas lines. Idk didn't make since to me.

Also I have my CEL randomly come one for 02 bank 2 and I believe my car may run rich I get smoke out the exhaust randomly some times. Especially when I sit at idle for a long time.

Idk if water has anything to do with my problem just was the big thing that happened right before this all really started happening besides the exhaust smoke that's been going on for a while

Is your air filter damp/restricted? Perhaps your MAF got fouled up by the excess humidity.

 

[mitecl96]

The air filter is fine. I cleaned the also to be sure it was fine, and oiled it like it's suppose to.

Well if you have a cold air intake and not a short ram you probably sucked up water. Usually when that happens something gets tweaked internally. I would do a compression check if your problem continues. I always put my short intake on during wet conditions for that reason

 

[mitecl96]

I'll do a compression test as soon as I can get a hold of what I need.

My intake doesn't set low low above the halfway point of the transmission.

I hope that isn't the case really don't think it sucked up water never got deep on the driver side

A compression test really wouldn't show a bent rod, which would result from hydrolocking. If you're really unlucky then you'd have cracked a ring/ringland. If the compression test comes back fine and you still want to confirm a bent rod, you can stick a screwdriver down each cylinder at TDC and measure the height of the screwdriver. Or you can yank off the pan and just check by eye.

If the engine was running just fine after the downpour then I don't think the issue is in the bottom end. It would have manifested itself immediately.

Engine seems to run just like before the down pour. I always had the smoke out the exhaust. The random idle and bogging down is what happened after.
