Default No power No CEL.... sometimes

I have a 2005 Baja turbo with 134k. It has ran great for years, but now I got a problem. It has happened twice in the past month, I turn on the car it revs higher than normal, revs fluctate, car shakes and when I try to move the car it has no power, cant get it to go over 20mph. Turbo is boosting, I cannot notice any smells, and no CEL comes on. So I parked the car, and then tried a few hours later and it ran brand new...!! So now when I get up for work i never know if im driving or taking the bus... lol ....... any ideas ? Because of course it runs great every time I wanna take it to the shop.

Car has cold are in-take, and up-pipe.

Is your maintenance up to date? I would start with cleaning the maf and resetting the computer.

Had the car towed to a subaru shop..... first they thought it was loose hoses, so they clamped them up left the car outside over night. Same problem in the morning, so today cleaning the injectors, checking the plugs and doing a compression test. :-)

All maintenance was up to date.

So this is really becoming a nightmare...... so the "subaru shop" was a big waste of money. They chargered me for a look threw, new intake arm, tune-up and reclamping a few hoses. 400 dollars later, they didnt find or solve the problem. Now there not to quick to get back to my phone call.

It wasnt that cold this weekend in Chicago, but I hadnt started my car in four days and this morning same thing.

Miss fire on 3 out of 4 cylinders, a burning smell by the passenger side if the engine. No power, and a lot of sputtering. 1 hour of running it settled down and ran normally

Please help :-(

Sounds like a misbehaving injector or o2 sensor on the way out

Well I picked up the car from the shop, they did the headgasket along with everything else that goes with it.....1500 dollars later the problem is still there !!!!!.... This is very very frustrating. I will try to unplug the 02 sensor next time the weather is cold. Thanks

Had a few cold days here in Chicago, and the last two morning car barely ran. The front 02 sensor code turned on the other day so I picked up a Bosch one, and will install tonight. Next will be new injectors and/or coils, unless anyone has any other suggestions

Wow, the shop told you it was a head gasket issue???? What led them to that conclusion?

Before you start throwing more money and parts at it with no guarantee of resolving of the issue, I'd look into trying to do some logging. Find a tactrix cable or borrow a friend's AP and try to get some logs.

Well winter has returned and so has my baja cold running problem. I've read about the legacy tumbler gasket issue, does any one know if we by chance share the same gaskets ?

Dude... calm yourself this is clearly a spontaneous issue that only rears itself when cold. STOP DUMPING MONEY INTO IT. when you ask a question on here how about waiting for an answer before asking then immediately taking it to a shop so they can just swap out parts with no real knowledge of the issue. How about this. You have aftermarket parts on the car without a tune I'm assuming. Try returning to stock! Get stock air box and go back to the stock up pipe. OR GET A TUNE FOR THE PARTS. I can tell you though the CAI is netting you nothing at stock turbo level and without a tune. And almost nothing with a tune.

You can thank me later.

Spark plug were done last winter, it didn't help. Car has the stock intake, I do have a cat less upipe , installed a few years ago. Im open to all options it could be the up-pipe. I haven't put any money in the car this winter, when warm it runs perfect.

What's wrong with the factory set intervals for maintenance? Other than the oil change intervals even my local tech disagrees and says it should be no more than 3k. But I digress.
