I Need Some Serious Help Please!!!!

[jay7227021]

sorry guys newbie here on this site but i need some help. the other day i drove through a huge puddle that i couldn't see because of a snow storm...after that i parked my car for work. 8 hours later i get in and drive and the car has rough idle, stalls while driving, check engine light on and at times did flash while driving, and runs really rough...it also had a significant loss of power and sounds loud like a bad exhause leak while accelerating with heavy sputtering. i pulled the codes and got 0705 and 0608 which are an evap leak that i know i had for a while and a cylinder 1 misfire that i have a hard time fixing due to a broken spark plug cooil boot around the base of the plug. i pulled all the coil packs plugs and the car would run pretty much the same. i check the mas air flow sensor and when i pulled the plug from that, the red power wire broke in half which ive never seen that happen before. anyone have any issue like this after going through a puddle?

Wow! Sounds like you have quite a bit of trouble since that pot hole. The only problems that can relate to a pot hole would be how the car rides, not how it performs. There is a good chance that if the car go jared hard enough it could have finished off a already brakeing part. First off you probibly have a bad coil pack. If the rubber boot around one of them is hosed I would start with that one and go from there. Get the mas airflow sensor fixed properly. Poor wiring in those can cause problems. Everything your describing can come from those 2 things. Most of them should be fixed with replacing the bad coil pack.

As water splashes into engine bay, just about every thing sucks water in. Some places it will eventually evaporate, connector(s), MAF, TPS, O2 & whatever sensors, relay boxes etc may now contain water/moisture that stays 'forever'. The water shorts signals causing the problems. Drying is the answer. How do you do and find your problems - no single answer - check browse link below.

Start from checking charge voltage, highly probable your alternator has fried. 90% cars you see in telly driving on flooded roads 'like boats', will definitely have severe problems...

I've had this problem driving through slush or water puddles - does it smell really bad? Our problem was the altinator overcharging. We would replace the Mass airflow sensor and it would die again. It took a long time to figure out it was the altinator which would overcharge and kill the mass airflow sensor (several times) and actually boiled the battery. When the underside would get wet the car would get sluggish and stall.
