Spark Plugs! (solution not found STEVE!)
I still need to know if sparks that fit a 02 will fit an 03, as nothing comes up under 2003 celica GT on sparkplugs.com but does for a 2002 celica GT.
I know it seems silly but I must be sure, same as brakes for an 2003 GT will not fit a 2000 GT, some times small things change from year to year.
Thanks again Steve, please don't jump the gun on me again.
