i have the 4cyl. '02 and under a normal accerleration the engine makes funny noise. i posted about it almost a month ago and someone gave me a link to Toyota Nation's TSB's but when i tried to open it i got an invalid response. after i couldn't open the link i went to the dealer and i was told that my warrentee is up soon but i waw told to try fuel additive (BG44k) or a higher grade fuel. neither worked and i only have 25k miles on the car. i thought i read somewhere in the group here that there was a TSB report on this maybe re: the manifold or something. i had new injectors installed in the car under warrentee back in Feb. because the check eng. light was on, but now this problem is not going away and the car sounds terrible when accellerating.
thanks...
