playford Posted January 22, 2015 Share Posted January 22, 2015 Hi all, I've been looking around to see about this problem and couldn't really find a definitive answer, so have come here hoping to find one. I've had the car for 3 months and seem to have a horrendous lag when accelerating mainly between 2000 and 3200 revs, after this the car is off like a shot. I've never owned a subaru or a 4 wheel drive so not sure if this is normal or not but doesn't feel normal. The fixes i found are an upgrade to the load on the ECU, Fuel pressure issue or a MAF issue. I've tries the ECU reset by unplugging the battery for a while and that did seem to make a difference but for a limited time. I've replaced all of the air filters and checked for debris. What was the version of ecu load that was having the issue, does anyone know? or has anyone else had this issue and knows the fix? Thanks Mark Link to comment Share on other sites More sharing options...
05legacysp Posted January 22, 2015 Share Posted January 22, 2015 Pull your plug wired and see if there's oil on the boots. If there is you have leaky valve cover gaskets and oil is interfering with the spark. Link to comment Share on other sites More sharing options...
06leg315 Posted February 2, 2015 Share Posted February 2, 2015 Leaky spark plug tube gaskets*** however the valve cover gasket may be leaking as well. Common. Link to comment Share on other sites More sharing options...

lancerswimmer89 Posted February 9, 2015 Share Posted February 9, 2015 I would check your o2 sensors, they might not be throwin a CEL, but when i changed mine out, this issue went away on my '99 Link to comment Share on other sites More sharing options...
SuperSub Posted February 16, 2015 Share Posted February 16, 2015 I have had the same problem. I do have a small oil leak from one of the plugs. But I have just changed the intake hose between the filter and Torque box to take out the restrictive path and this has seemed to have helped.
