do you have any eng codes? how many miles on clutch?
code p0446
vehicle has 189,000 kms
Sounds like your clutch needs to be replaced.
kind of figure it out,i was a bit trow off by the code p0446, but the other night i got stock in traffic and the rpm was fluctuating, so i installed a Mass air flow sensor and replaced the gas cap, everything if find.
the clucth is a bit sluggish because i bought the second hand and i have been driving the car for six month only!
i will install a new clucth next spring.
thank you all for the reply!
