advanced6258 Posted December 7, 2007 Share Posted December 7, 2007 I own a 98 subaru outback. The head gaskets went so me and my buddy pulled the motor and replaced them and dropped it back in. Car starts fine but has small misfire. Im not worried bout the misfire what im worried bout is that when the car is in park and neutral she revs fine. When shes in R,D,3,2,1 with the pedal pushed down to the floor she crawls literally, until she hits 3500 rpm then she has all the power throughout the rest of the powerband, then when she shifts and drops under 3500 rpm she does the same thing.

RallyKeith Posted December 7, 2007 Share Posted December 7, 2007 Have you been able to do compression or leakdown tests on the rebuilt motor? Quote Link to comment Share on other sites More sharing options...

CNY_Dave Posted December 7, 2007 Share Posted December 7, 2007 I have seen this lotsa times (in other vehicles) due to a bad/loose plug wire, or a cracked plug, etc. Dave Quote Link to comment Share on other sites More sharing options...
montana105 Posted December 7, 2007 Share Posted December 7, 2007 Did all vacuum lines get hooked back up,especially PCV? Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted December 8, 2007 Share Posted December 8, 2007 Hi, sorry about that; I think I misread for my first post. How about timing, are you sure that's dead on? One tooth off and it'll have power loss...more than that it probably won't even start. It must be perfect. Also knock sensor can cause some power issues.
