idle problems

[Guest magico]

I hit some water 3 weeks ago on the way home from work , a couple minutes after encountering it the engine wouldn't pull anymore to the point where to start off i have to go in "low" then 1 then to drive to actually make the car get up to speed fairly quick . I drove it back to and from work for 2 days ( about an 8 Mile return trip) thinking thats its probably water related so i was hoping it would dry out and clear. the car now pulls better but is idling extremely high .in "drive "it stays over 1000 revs to the point where im pressing down hard on the brake at junctions to stop it pulling forward , also when i put it in" park" it fly's up to 2000 revs and keeps on dropping up and down betweenn 1200 to 2000 extremely annoying. any help would be greatly appreciated

 

2. i also and have had for sometime a very annoying knocking /rattling noise when i go over bumps. ive got a feeling my suspension maybe on its way out ,

1. Sounds like the automatic choke is staying on. Not sure what controls it though. Also, you said you'd reset the ECU thinking that it might be an ICV problem, but AFAIK the ECU doesn't directly control the ICV. I might be wrong though. The ICV itself might need replacing.

 

2. As RobSheffield said in the other thread, check your suspension components and make sure the subframe bolts are all tightened up properly.
