lexus200

Hello,

i have a lexus is 200 , 155 Ps, . The motorcontrollsign got active and I went to the mechanics. They found a lot of error codes - not only one. When the sign for the motor lighted, I didnīt continue drive for a longer time - estimated 30 km. What I found out : It was strange, that the motor didnīt run linear und still, but I could hear a small difference in the sound of the motor . the motor sound went up and down in a way like a wave. The mechanic found the following errorcodes : P0300,PO302,PO303, PO306 and P1305, P1310,P1315,P1320;P1325. They told me, that they dont exactly know, what they mean, and that it wound take al lot of time for them to find it out - and for me this would ment a lot of money. Does someone know these codes ? Or has someone an idea ?

thanks, Sophie
