-SHIFTY-

My 07GT is acting up a bit. I ran through some water the other day and noticed it running a bit off after. It flooded around where I live and I had to go through about a little less than a foot of water to get out. Steady speed the car didn't sit in the water. My GT is lowered so I'm wondering if water got on my o2 sensors and is causing some issue? Car runs rough - idles weird - doesn't drop RMP's right away inbetween shifting, its like it lags. When it drops under .75 RPM (normal idle) it makes a swual low tone whistle noise. Also does this when you shut off the car. I think its a air fuel issue - any ideas? Been 2 days now still acting up.


Thanks guys

hi, sounds like same issue I am having......did not go througha puddle....but when cold...idle is really lumpy...you can feel it in the car.....I changed the plugs last week, that did not fix it.....I checked all my connections to the plugs, and injectors, put a new gas cap on.....I had cleaned the MAF and throttle body a few weeks back.....
I am stumped.....I did notice that at first after the plug change I thought all was good, but then a few days later the really lumpy idle startedwhen car is cold....HELP!!!!
