Today as i was driving i couldnt help but to drive into a decent sized puddle. But after the puddle i drove home just fine. I later go to leave and my 91 legacy starts to act up. The motor now runs ruff and i have allmost lost all the power in it. If someone can help it would be much appreciated.

do you have a cold air intake?

Depending how big the puddle was and how long it was running rough, you might have a cracked knock sensor and water got into it

Also check the spark plug wells on the heads & other associated wiring.

No i dont have a cold air intake but i have cut the bottom of the stock air box. I cheaked the air filter and it wasn't wet. Where is the knock sensor?

If you look straight down at the engine around the area where the throttle cables hook up to the throttle cam, you should see a round black thing with a wire coming out and a bolt going through the middle. That's the knock sensor.

I believe I labeled it in these pics.
