i bought a 1999 v70 t5, instantly on the way home from buying the car the rev's were erratic, on tickover it do not go over 1000 revs but it drops so low to the point of cut out.i have replaced maf sensor and there still no change revs still erratic and spits out a lot of fuel, have ordered 2 oxygen sensors as the code reader says they faulty. although i can't see how they affect the throttle i checked all air flow pipes and they are fine, im really at a loss now n i luv the car! any help/advice greatly appreciated! thanx.

 

Check for vacuum leaks.
