i have a 03 tiburon gt so im having many problems with my car my clutch went bad TWICE and then about 20 miles i got a new clutch. my radiator cracks. then about 10 mins after my radiator cracks. this weird thing starts with my car. i cant go past 3000 rpm. i have NO IDEA what it is. but all i know is that i got my radiator fixed and it thought that would fix it cause it happened right after my radiator cracked. but no. it runs normaly when its cool. but once it starts heating up i cant go past 3000 rpms. god i think i have a lemon car. but i heard that since its a used car. you cant claim it as one. then to top all this off. my airconditioner had a bad line in it. and my right rear axle baring went bad. my car has 70800 miles on it. i just dont know what to do. i got all this stuff fixed exept the weird 3000 rpm thing. and i just patched up my radiator. its just temporary till i get a new one.

Dear rubber,

do you have a Check Engine Light on? Your problem would surely cause a Check Engine Light. Go get it read for free at Autozone or Checker Auto parts. The Autozone counter attendant will not only tell you what code(s) you have, but also the logic tree to fix it.

Also, go to hmaservice.com, register, and look thorugh the DTC (means Diagsnotic Trouble Code) tables.

Sounds like a throttle position sensor to me, but I diagnose instead of part swap.

hope you have waranty
