Okay, my car has gone goofy in the last 24 hours. I just drove it and the idle is jumping between 500-1500, it idles rough and almost dies when in gear, while in neutral it seems to idle better. While at speed the car surges and feels shaky at 80km/h (50mph) or higher. Then on my way home today the ABS/Brake warning lights came on and the dash lights were flickering like crazy, I turned off the heat and the radio and threw it into neutral and the flickering went away. I just had a new battery installed about a week ago, I am thinking the mechanics didn't tighten the posts properly and maybe this is the source of the problem.
Could an unstable battery signal cause these problems? all the material on this site seems to suggest that sensors and spark plugs are responsible for the symptoms I have listed an unstable battery signal can cause sensors to fail and improper charge to be delivered to the spark plugs right :?:
The other thought I had that I am going to check into is maybe the transmisson fluid is low.
Please let me know if any of you have any thoughts on this
