'92 240SX Ka24de problem

[JStrateger]

I really need your help guys.

I just recently had the engine intake a bit of water by connecting a water pump hose to the intake by accident. (Yeah I know, I'm beating myself up enough about it.) I believe it is all flushed out from me running the engine for about 20 minutes, I used starting fluid to get it started. It was running fine at about 1500rpm, no real idle problem.

I turned off the engine after thinking all the water had been pushed out. ( There wasn't that much) So I let the car cool down and put some water in the radiator and go to start it back up. The car starts hard but it does start and stays running at about 200-300rpm. The engine doesn't respond to the throttle, I'll pump it and nothing changes.

Run down:- Engine starts hard and idles at 200-300rpm- MAF (Works fine)- ECU is throwing me a 34 (Knock sensor which I replaced, not sure why it's still throwing me that.)- I checked all the grounds. The ground is reading at zero.

Help, I'm stumped.

Edit: When it's started, if I hold the throttle to the floor it will eventually climb to higher RPMs. The throttle very slow to respond. If I let off the throttle it will return to 200-300rpm.

whatd you stick a garden hose on the intake or something? Umm, maybe you need to disconnect the battery for a while, after so many start ups the computer resests or *fixes* itself. so it may take some time, Also, check the accel. sensor, water does wonders for electronics

I mixed up a vacuum line which came from the right of the throttle body with a water hose that went on the side of the throttle body.

I checked the ECU and nothing came up.

I messed around with it a bit more today, replaced the spark plugs since they were dead from the water damage. I started it back up but it wouldn't start by itself, I had to use starting fluid.

I had to hold the damn throttle to the floor to keep is running, exhaust was clean, It sounded like the pistons were hitting the valves.

This doesn't make any sense to me though because that would mean I'd have to adjust the timing if they were hitting, right? The timing was fine before it sucked in the water?

I'm so confused and the only thing I can think of is that I killed my motor.
