last night i had to drive home from work in a downpour and about 5 miles from my house my car wanted to die at a light, it started shaking so i pulled over on a side street and let it idle a few minutes and it idled fine. as soon as i put it in drive again i had the same problem. when i tried to get on the gas it felt and sounded like the engine was being suffocated, it would accelelerate about half as much as it should then would randomly jump a bit to where it should be, i couldnt really get above 30 mph. i thought maybe the air filter being soaked might have something to do with it but today the same thing was happening. the opti could have easily got wet so thats what im leaning towards the problem being.
thanks for the replies. yes the ses light is on but its always been on because i dont have rear o2 sensors tuned out. yes its still happening today when everything is fully dry. i have a moroso cai and the filter was pretty wet. i think i might just go ahead and order a opti off ebay from chandler motorsport. seems like there are alot of mixed feelings about that company but they are cheap. what do yall think?
I vote opti got wet, this happened to me in texas one evening. After plowing through a puddle and water basically going over the hood the car didnt want to move under throttle. It would idle rough, and then idle fine after a bit of throttle work but never drove the same in traffic that night. After drying out for a day it was fine and lasted another 10k miles and then I sold the car and it was still working fine. Daily drivin too.
Hopefully you get lucky and this is it!

alright guys so after letting the car dry a bit more the issue seems almost gone. the idle is still a little rough at times and i noticed the rpms jumping back and forth between ~1000 and ~1500 when in drive just rolling along at 10-15 mph. idk if the wires in the maf getting wet could cause this, but i doubt it has anything to do with the o2's (i have extentions). i'll make a trip to autozone tomorrow to see if i have more codes. thanks again fellas
well it finally stopped raining so i tried maf cleaner as well as throttle body cleaner and no such luck.
i've determined its all about the start. sometimes it will start up just fine and drive just fine as well. other times the start will be a little rough, and then i have my problem where it feels like the car doesnt want to accelerate.
but heres the thing, if i have a bad start and i have this problem i can just pull over and shut it off and restart it and sometimes it will run fine, sometimes it will take 2 or 3 restarts.
so it depends on how the car starts. i feel like its something so simple like something is just loose, but i just can put my finger on it.
