my issue with code 43 was fpr
/sig
sometimes fpr or just a bs code for evap purge system or bad gas cap maybe. this is the hardest code to figure out. i used to only get it with a p28 and pop my p30 in no more problems. nothing to worry about id just turn my ign off going down rd then back on and clear it sometimes it wouldnt come back for months.
LET ME GUESS... YOU MISSED A GEAR!
When my car threw that code it was te fuel pressure regulater on the end of the fuel rail the one that holds the fuel line to the rail the one with that plastic cap on it

fuel return line that is on the drivers side! do you have an after market fpr? if so it usually makes the code kick!
