I just got the car , after changing the oil, and topping off some fluids. i took the car out for a fast run. Moments after slamming the gas the car goes into reduce engine power mode. When the car downshifts you can feel something is wrong. I notice that a tube is missing from that relay? or ground plug? i found the rear one lose and plugged it back in.
On my first run (with the lose hose) it Reduce engine power and throttle problem did come up.
After i plugged it back, just the reduce engine power.
