Engine Mechanical problem
2000 Saturn SL1 4 cyl Front Wheel Drive Automatic 85000 miles
My 2000 Saturn has had all the regular maintenance done, including a full tune up and servicing in Sept 2008. Recently the engine starting increasing rpms when the car was put into park or neutral. At first the problem was intermittent. Now the engine revs all the time, running at about 2500 rpm, although once in a while it goes back down to 1100 rpm. I can drive down the road at 35 miles an hour without ever touching the accelerator, and in fact even have to brake to slow down sometimes. I was told it could be vacuum hoses or o2 sensor, but this doesn't make sense, as the o2 sensor was changed in 2006. I have only owned the car a little while, but the previous owner claims no knowledge of the problem and gave me all the maintenance records. Now the car is starting to misfire as well, again, even though it had the recent tune up.
have the same problem?
