Im really thinking its the plugs. i had the same problem when i first had my SR. i put new plugs thinking Bosch's was all hot shit and they got eaten up quick.i mean like one run quick.Same problems though, bucking higher up in the rpms and crappy idle and driveability but they were also the wrong heat range but i didn't know. put in NGK BKR7E and problem was gone. bought like 12 of them last time so i always got replacements.
