I was wondering if anyone could help me... I have a 98 svt contour. It is stock and has ~93000 miles. Recently, the car has been losing power on the high end (after 4000 rpm). It doesn't sputter....it just doesn't have the power that it should (ie it doesn't pull to the redline with tenacity). I brought the car to the dealership and they did a tune up, replaced fuel filters, and recent replace the ICV (the car started to idle poorly). These things fixed the idle trouble and the power loss for a while, but the power loss has returned. I should also mention that this doesn't always happen. Sometimes the car runs fine and has plenty of power. The dealership doesn't seem to know what to do since no codes show up and they just did the tune up. Anyone have any ideas???
Also, the car revs when the AC/defroster is on. Any ideas why this happens? I believe that it should lose power when the pulley is engaged.....not surge with power.
Thanks
