i sent my 2007 350z to get whole clutch replaced including flywheel (z1 motorsport clutch with light weight flywheel) when the guy replaced it and try to drive it, it was stuck on limp mode.idles under normal and doesn’t rev over 1,200rmp, and doesn’t accelerate .the car was running fine when i drove it to him(30miles)even with a bad clutch and now he claims he installed everything right and it must be something different.
we tried cleaning throttle body and removed cats and still the same issue,STUCK IN LIMP MODE i tried the ecu reset and idle reset but not working(doesn’t idle over 1k)
i have been looking and it can be many things, only check engine light code that popped up was p0507
i was reading that if flywheel isn’t alligned or installed correctly it can be put into limp mode
HELP PLS
(car was running normal before the whole clutch job just rpm’s would fall when i would accelerate {clutch slipping} don’t know what else to do

 

Sounds like the flywheel was installed in the wrong position. This throws off the timing.

Unfortunately, the only way to check is to drop the whole tranny again.

 

goes into gear but car stalls if i let go of clutch pedal and doesn’t go over 5mph literally clutch needs to be engaged the whole time
idles at 800rpm and when i rev (foot to the floor) the max is 1400-1500rpm
oil gage reads low but before the clutch job it was the same and it reads the same

 

Flywheel was installed wrong or he broke the crankshaft sensor

 

Interesting how when it rains, it pours (with similar sounding issues with similar sounding fixes).... https://my350z.com/forum/2003-2009-n...th-my-car.html

By the way, for this poll, I vote "limp mode".
