Please note that the oil and water are ok. Just had new leads, plugs, knock sensor, C02 sensor, PCV valve.

Hi I have a 1998 legacy wagon 250T, EJ25. After driving the engine appears to give off, what I would call it as a hot smell, that's the best I can describe it. It is driving ok, seems to perform satisfactory and doesn't heat up according to the temperature gauge. Is there anything I should be concerned about or need to get checked out? Is it something that could lead to a more serious outcome? If it wasn't for this smell I wouldn't be at all worried about it other wise. Any advise or suggestions is much appreciated.

Hi willwright. Thank you very much for the great support, and thank you to everyone else who replied to my post, it is all very much appreciated, it's a good feeling when there is plenty of support out there when you have a problem. Just to inform everyone out there that I have fixed the problem of my legacy having that flat spot, poor performance issue. As I've said, I replaced co2 sensor, knock sensor, plugs, leads. After putting my issue on this forum, as suggested, I then replaced PCV valve, Cleaned MAF sensor, put foam through intake, it's like driving another car, performing very well. After taking the PCV valve out it was obvious that it was quite gummed up and needed replacing, I would say that was the problem. I would advise to everyone with a subaru around the same age to just replace this valve, it only cost me $40 genuine subaru, and took 5 minutes to replace, it was the easiest and cheapest part to replace and am very surprised more people don't recommend to just replace it. I have certainly learnt a lot by doing all of this, and found out a lot of information on this web site. Again thank you very much to all of you that helped, it was the advise from you guys that got me there.

Do you simply just put the sea foam into the air intake at the engine where the intake hose connects to the engine? Sorry, I do have mechanical knowledge but I am learning as I go with this car:)

Thanks very much for this, I will definitely try these things.

I see a lot of people using "sea foam" what is this? Is it another term or brand of injector cleaner?

Hi. Yes mine goes away once it gets the revs up and gets going, it's almost like its thinking about what it doing.... I have also put engine/injector cleaner in it. All parts I changed have been genuine subaru parts. I forgot to mention that on occasion it did bucker around for a short time while driving at constant speed and low revs, but I haven't noticed it do this since I have made the current repairs. Intake, you talking about air intake? I will definitely try and disconnect battery over night. Sorry, I'm not up with all the short references, MAF, IAC, EGR, could you extend them please? Thanks.

Yes I agree, parts changing is very frustrating. I will have a look at vac lines ect.. Thanks. Might need to removed injectors and have a look, any tips on removing injectors?

Yes NGK laser platinum plugs and genuine leads from subaru, all looks ok. this issue was happening before I started changing parts, just hasn't fixed the problem yet. Thanks

Hi everyone, I am new on this site to see if someone can help, hopefully this works. My 1998 legacy 250T EJ25 wagon has, what I would call a flat spot, or lag even though it's not turbo. It is happening at low revs when I accelerate from lights ect, or just when I want that extra little bit of speed, it does eventually get up and go but just seem to take a while to sort it self out. I took it for a good blow out on the open road and went very well. The CEL is not coming on. I have replaced the knock sensor, Co2 sensor, spark plugs and leads. Other than this frustrating flat spot, it is going well and idles fine. Does anyone know of this problem which can point me in the right direction, or should I carry on changing maintenance parts next would be fuel filter?? Or could it be something like TPS, ECU mapping ect...... Which I would have to take to a specialist. I appreciate any help. Thanks Pete.
