Car was flooded and need all the help/advice I can get!

Tbh I’m not really good with cars in general, but with a lot of googling and the great online civic forums I’ve fixed every single thing on my 2001 Honda Civic LX thus far. I’ve used my civic to do delivery gigs to pay for my daily driver until about 3 weeks ago when we had a bad storm down in Houston my wife drove it into a ditch and… well here’s what I’ve done so far:


-Took carpets and seats and dried them out in the sun

-Cleaned and used CRC Wire Dryer on every connection I could find inside cabin and engine bay

-Thoroughly cleaned control modules/fuse boxes with alcohol and used dielectric grease
-drained fuel lines and tank (didn’t replace fuel filter)

-new air filters

-flushed power steering wheel oil

-new radiator/antifreeze (radiator was cracked)

-3 motor and transmission oil changes (will do one more and use some oil treatments to be safe because water got inside transmission due to a bad dipstick that was too loose)


**I made sure I did all of this before starting it cause everywhere I looked they said starting it with water still in the engine will surely finish it off.


Now here’s the problems I’ve had so far:


-Engine light throwing code P1519; Idle air control valve (IACV)
circuit malfunction

-It idles from 1500-2500 RPMs going up and down at random times

-It sort of sputters when I drive, especially while cruising

-Automatic transmission makes a louder *thud* sound when shifting even though shifter itself is smooth

-SRS light on




I know this ain’t a walk in the park and friends have all said that I should give up and drive it up to the junker to take it out of its misery— but I’m on a budget and can’t just go buy another car right now, so any help I can get is greatly appreciated. I’m surprised the car started after all the stuff mechanics have told me honestly so I’m still hopeful. Best case I can get a year out of it and either way have learned a lot working on it!

Remove and clean IACV and filter screen with brake cleaner spray. Clean throttle body too.

Thud sounds during shifts inspect motor and transmission mounts. Additives such as Seafoam Transtune and/or Lubegard Red may help (use at your own risk).

SRS...search related threads here.
