1999 OBW 2.5l A.T.
had a low idle (below 700 rpm) & sometimes wouldn't start right up after a short stop (but it always started 2nd time). So, I risked my knuckles & replaced the spark plugs & wires (double platinum NGK/mid priced house wires). ran smooth but noticed that at a light it would idle smoothly, then suddenly shudder, & then resume a good idle (still low, though)... it is consistent problem. The problem is much less noticable if I put the car in neutral.
I have replaced the PCV valve, the air filter, the fuel filter & I can find no vacuum leaks... no difference.
It also seems to have a lot less pick up than my current wife's '02 Impreza Outback Sport... (that goes like a bat outta hell)... but it never did. It has plenty of power for long trips & can cruise smoothly at 80 mph... although I *never* do that.
any help, suggestions, ideas... wisdom?
