i would also like to add a strange issue that also occurs frequently..sometimes when i am sitting at a light with the lights on and it surges a few times, often it will enter what i call a limp mode.. wht happens is it stops surging but when i begin to accelerate the car will not go over 2800 rpms..when it gets to this point it begins to sort of buck/hesitate and i have to let off the gas to let it switch gears..i must shut the car off and then restart it for it to run normally..no clue but this problem is so peculiar.. might this sound like the alternator/regulator?? thnks for all help
