Check engine turns on in 5th gear.
So my check engine comes when I am in 5th gear right above 3000rpm's. car doesn't seem to sputter or anything just keep going like nothing is wrong. Also the temp. On the car is about normal maybe just below midpoint on the gauge on my cluster. Ask my instructor who owns about 3 rx7's all he could say was that its weird. This only happens around the described conditions if I push in the clutch the check light turns off. I have no idea what it could be and neither do any of my teachers at my tech school. I'm assume its something with the gears but that's with limited knowledge on them since we have only gone into depth on brakes so far.

Check codes: 89-91 CPU Trouble Codes
The temp gauge on an S5 is nothing more than a "warning light" with 3 settings:
1) Cold
2) Warm / Operating temp
3) Rebuild
The S4 water temp gauge is actually linear and useful.

My throttle body is sounding like it might be the problem, replaced it recently might of did something wrong while putting it in. I will still check for codes.

i was just doing research on my s4 manual trans and there is a "5th gear switch".. i have no idea what it does or what its used for but that might have something to do with your problem. Ask your teachers what this does.

The 5th gear switch also prevents the shift-up light from coming on in 5th gear.
