GLCraig Posted May 28, 2005 Share Posted May 28, 2005 Have you tried cleaning out the EGR tube and is the EGR valve working correctly? Also, what temperature thermostat do you have and about where on the gage is the needle staying when the engine is warmed-up? Link to comment Share on other sites More sharing options...
Cougar Posted May 28, 2005 Share Posted May 28, 2005 Have you tried looking at the timing or changing the distributor position slightly? Link to comment Share on other sites More sharing options...
starkiller Posted May 28, 2005 Author Share Posted May 28, 2005 timing is at 20degrees...advance it more and it gets real loud...less and the ping seems to be better but its a dog then...thermostat stays pretty low all the time, probably around 1/4....

ballitch Posted May 28, 2005 Share Posted May 28, 2005 is it throwing any codes or is it just being a subaru? I think taking it down to about 18 degrees BTDC should do it, have you tried unhooking the battery overnight, or for an hour or so, to reset the ECU? better the computer be reset and re-learn the way you drive than for it to ping inself to death. the temp needle should be alittle below halfway when fully warmed up, the EGR vlave suggestion would probably be a good place to continue looking. ~Josh~ Link to comment Share on other sites More sharing options...
hooziewhatsit Posted May 28, 2005 Share Posted May 28, 2005 Have you tried cleaning out the EGR tube is there a way to do that without removing the intake manifold? I just tried on my SPFI and it doesn't seem to want to come out. Is there a trick I don't know? Link to comment Share on other sites More sharing options...
