Why do my blinker lights turn of and on after resetting the computer on my car?
After disconnecting and reconnecting the neg. battery term. on my 1997 Subaru Outback Legacy to reset my car's computer, the front and rear blinker lights turn on and off continually.

Additional Details
I needed to reset the computer because the check engine light was continually on and after putting sea foam in the gas tank the check engine light does not come on! Just the rear tail and brake lights and the front turn lights along with all the dash lights turning on and off continually.
How do I take care of this new problem???

Im going to guess and say that your not a mechanic or that you have some very basic mechanical skills. I am a ASE certified master mechanic and have some info for you so lets get started with Automotive 101. The reason the lights keep blinking and computer didn't reset is very simple, YOU HAVE TO HAVE A OBD II SCAN TOOL HOOKED UP TO THE OBD II PLUG LOCATED NEAR THE STEERING WHEEL AND BE LINKED TO THE CARS ECM VIA THE SCAN TOOL AND BE IN THE ECM CODE CLEAR MODE AND PUSH CLEAR BEFORE FAULT CODES WILL BE CLEARED FROM THE ECM MEMORY. Without a scan tool disconnecting the battery cables is a waste of time, sure in the OBD I systems that was possible but cars built starting 1996 have OBD II and clearing fault codes HAS to be done with a scan tool. The lights are flashing because your car has either a aftermarket alarm in it or one from the factory. When you disconnected the battery cables and then put them back, the alarm ECM reset itself and the system has a light flash mode that has been activated. You have to find out the type of alarm system that is in your car before attempting to turn off the alarm system. How do you determine that? You have to have experience with cars to know how and where to look, explaining in type is not easy.

YOU don't take care of the problem! That's obvious because you just drove around with a CEL lit and never did anything about it! Ever hear about getting the codes read? Now you F'ed up the electrical system. What did you do? Disconnect the battery with the ignition turned on? Or did you put the only 2 cables back on backwards? I'd close the hood and find a mechanic before you ruin something else!

it must be "fastened" or it must be that it will misfire back. the element with misfires is they are intermittent activities, in comparison to declare an O2 sensor which will flow undesirable and stay undesirable. Anecdote time, I had a ninety seven civic that threw a misfire code after a coarse initiate. I reset the code and it in no way got here back for the two years after that I owned it.
