Hi
My car is a 2005 Subaru WRX Sedan. It has 37000 miles and has had all the regular servicing.
Last night I did some highway driving (25mins) and then was in city center stop/go traffic. After about 10 mins in the congestion the revs started to increase when idling (clutch disengaged and in neutral). Typically it sits at about 600rpm or so when idling, it was started out at 1500rpm. After another 5 minutes it had passed 2000 rpm, another 5 and it was close to 2750rpm. Felt as if I was holding the accelerator down constantly. I didn't have any engine management or oil lights showing on the dash, and temperature wasn't any higher than normal.
Only thing that reduced the revs was to put the car into 1st or 2nd gears and engage the clutch. Doing this made the car feel like an automatic - no need to put my foot on the gas. I've probably done some damage to my clutch, but wasn't sure of possible damage from the high and increasing revs.
I found somewhere to get my car pulled over and I turned off for
15mins or so. When I started it up, revs seemed normal again, and I was able to get the car to my mechanic since I was near the highway. On the highway driving the car performed as it had done earlier.I've left the vehicle with my mechanic now, and am expecting a big bill! Anyone have any thoughts on this, or experience anything similar?
