lately ive been having this weird rev limiter problem like in EVERY GEAR, my car is hitting the 5th gear limiter at 5.5k rpms. i crawled under the car one day during an oil change and i was just checking the transmission sensors just in case maybe the 5th gear sensor was disconnected or something and it seems like the 5th gear sensor was halfway plugged in. so i push it in till it clicks. the next day i wanted to try hitting redline again, so i did a 1st gear run and BAM! i hit 6.5k! i instantly pull to 2nd gear and BAM! 5.5k limiter...! wtf? i try the 1st gear pull again and 5.5k limiter again too!... whats going on? would unplugging the 5th gear sensor make ur rev limit mess up? and if it was unplugged the whole time b4 i replugged it, how come my 5thgear speed still shows up!?
