sonoransubaru Posted September 8, 2006 Share Posted September 8, 2006 Two days ago, I drove my '98 Legacy L through a flooded street (unavoidable). Within a mile or so, the check engine light came on and the engine began to sputter. Accelerating from a stop became difficult. Since that time, the engine has begun to sputter less and the acceleration has improved, but not to the point of normal. 1) Can anybody offer any suggestions for a fix? 2) Will the fix reset the check engine light and, if not, is there a way to do that at home? (We had the knock sensor replaced two years ago and I seem to recall the check engine reset procedure was complicated.) Many thanks in advance.

nipper Posted September 8, 2006 Share Posted September 8, 2006 how deep was the water. Did the car stall in the water at any time? Basically you have water someplace the car doesnt like. The lowest thing would be the 02 sensor. Next thing to be upset would ignition wires at the plugs, then it could be any number of sensors after that. How many miles on the car When was the last time it had new wires on it. Can you get the codes pulled from an auto store. Fresh or salt water nipper Quote Link to comment Share on other sites More sharing options...

porcupine73 Posted September 8, 2006 Share Posted September 8, 2006 You gots ta get da codes read, that will probably reveal much info. Reset is easy with even a basic code tool from my experience. Most places like autozone will read da codes 4 free. Quote Link to comment Share on other sites More sharing options...
nipper Posted September 8, 2006 Share Posted September 8, 2006 may be as simple as an angry o2 sensor, or wet connections, but we need codes nipper Quote Link to comment Share on other sites More sharing options...

tcspeer Posted September 9, 2006 Share Posted September 9, 2006 I think you only need to take the battery cable off and leave the hood open for a while it will dry then run fine and the light will be off, after putting cable back on. This happens often after washing engine with hose or at car wash. you might want to take the plug wires off and dry the plugs and the end of wires.

SuBrat84 Posted September 10, 2006 Share Posted September 10, 2006 After you get the codes pulled and see what it is for.. (sounds like a misfire caused by a water short, etc..) and need someone to work on it.. I can help you out. You may just need new spark plugs / spark plug wires. I drove my 98 GT through washes up to and above the headlights before... I was putting H2's to shame in my sedan! Quote Link to comment Share on other sites More sharing options...
Manarius Posted September 10, 2006 Share Posted September 10, 2006 Yeah, I bet it has an angry O2 sensor. Reset the ECU and go from there. If it's still acting mean, get the codes read. Quote Link to comment Share on other sites More sharing options...
xrturbo Posted September 10, 2006 Share Posted September 10, 2006 i agree with where nipper is goin, sounds like an issue i had with water trapped in between the plug and boot. try pullin the plug wires and see if the tip of the boot is wet. you dont have any type of cai on the car do you?
