Bstorey02

yesterday when i drove my car the check engine light was on... I get in tonight and its off... I talked to a subaru tech tonight, he said that it could be a programming problem and the ECU needs to be flashed... I tried to turn the check engine light on tonight and it did not happen. the plugs looked pretty much the same, they had a red color to them, no one was burnt more than the other.

when im braking hard from a high speed my steering wheel shakes bad. have asked a few people and they have said its the abs kicking in... i know what abs feels like and thats not it. im not slamming on the brakes just trying to slow down fast. i have read the other forums and have seen that is could be warped rotors. could this be the problem?

i have an 02' wrx. i had a missfire on the number four cylinder during heavy exceleration, i changed the plugs on advice from my mechanic. changed my oil and put new plugs in about 2k miles ago, check engine light stayed off till about a week ago and now says i have number four cylinder missfire again. any ideas?
