My car recently began to act up. The engine loses power at 5k rpm, and sputters. i cleaned the air filter, fuel filter, and mass air sensor, but its still messing up. I need my power back- there's a guy in a local town that is convinced his mr2 can outrun me, and i need to break his heart- help a buddy out, and lets make a suby snack out of a toyota. -thanks everybody.
i've outrun mr2 turbos w/ upgrades before- and they had good drivers- this kid's 16 and uncoordinated
as far as everything else, the weather's been the same, it's got supreme exxon in it. i got rid of the cat, thinking that could be the problem, but it wasn't. i took my boost controller off, and had a buddy at my local shop clean everything and check it all out. we're flustered
maybe the cai causing problems, I now have my cai installed on a shelf in my garage,(works great there!) however, look into the plugs and coil pack boots, you may have carbon tracking on the plugs or boots. I just had a problem with that about 2 weeks ago. if you see any lines down the plugs or in the boots replace them both otherwise it will happen again with new plugs.

Going on the fact that nothing "MAJOR" has been done to the car concerning mods, Check your plugs for carbon build up, or wetting, air sensors are not nackered, filter not good, poor fuel from local garage, it does happen!!, are you on new fuel from different station,from last fill up, Have you been idling scoob for to long berfore booting it as they are built with safety features to control boost after long periods of 1.5-2rpm,
Hope you get sorted stone,
Hey I am having the same problem with my 02. You put the pedal to the floor and right after 5k it feels like it is looseing some boost. I have owned mine for a month and it just started doing that a few days ago. I have been threw about 3 tanks of gas since then and it still does it. The only mod I have done to it(if you want to call it a mod) is the removal of the silencer. I didn't see any carbon tracs so I know the spark isn't arking. I havent gotten to take it to a dealer yet, but I am going to soon before I put an exhaust on the old subby. I am going to hook it up to the drb or the snap-on computer(which ever one is compatible) to see if it is getting a fuel pressure drop or a loss of spark or any change in something that isn't supposed to fluctuate.
thats the same plan i have. i've checked everything, run new gas through it, EVERYTHING. i'm just gonna let subaru's tech guys have a field day on it, and be broke for a while. i just want my baby back. let me know what the dealer says about yours since warranty still covers yours. once again, i really appreciate the replies. i've learned a ton on these forums, and want to tahnk everyone who shares their knowledge.
what do i do to fix that? part of the vacuum line has excellent vacuum, part has next to none. i can't remember which section was which, but we couldn't find a solution. - i bought a vishnu unichip- wasn't that supposed to fix the fuel delivery, or is it because its only a piggy back that the ecu is still trying to compensate- i'm learning
