Help 2007 STI delay betwee 2500-3000 RPM

[momscar]

Please help; I am experiencing a "delay" between 2500-3000RPM in any gear. For instance just got the car back tonight from shop and they said it was fixed I was in 6th doing 65 car was running between 2500 and 3000 Rpm and the car "sputtered" is the only way to describe it. I just spent 900$$ for the 60k maintenance and unessicary oil change. They claimed the issue was caused from my oil being low. Funny thing is they just changed the oil and the level is good (I checked myself) and it’s still doing this. I suggested that it was a fuel line or FI issue and they looked at me like she's a dumb girl and has no clue....... They checked all sensors and they are good.

If anyone else has experienced this problem or has any suggestions please let me know. I have had my car for 3 1/2 years and had no problems with it until now and am really frustrated w/ the dealerships... They are killer for labor cost but I do love my car!

Thanks

Are there any modifications done to the vehicle? If so, we need to know. There are several causes for this. Could be an issue resolved with a simple ECU reset, which would entail removal of the negative battery terminal, holding the brake pedal down for about 30 seconds, wait a minute or two, and reattach the cable.

find an independent subaru specialist. the dealerships all employ morons whom just recently finished mech. school. the have no real experience.

Are you getting a check engine light? Just a suggestion but could be a dirty MAF sensor

Thanks. There are no mods done to it. They've checked all sensors... But apparently did a 60k mait. And my coolant Resivor is almost empty. So yep.

Could be lots of things but with out seeing the car in person or having a CEL/DTC to start with this could go lots of different ways. Maybe there is a bad spot in the TPS or the spark plugs need to be changed. First thing I would do is clean and re tighten all grounds and the battery connections.

Thanks again the shop has my car yet again they are still claiming an oil issue. Just changed spark plugs and they have checked all sensors and connections. I do appreciate the help and ideas.

Definitely not an oil issue. I would try a second opinion

Ya they finally ruled that out duh they wouldn't listen to me they accrually have Subaru involved that's how bad it is.

Hi, I have a 2007 wrx tr and I just started experiencing the same problem. It's really annoying because i know their is something not right with my car. My car is still under the extended subaru waranty so i brought it in. Here are a list of issues i had with my car and what the dealership found.

1.knocking from rear suspension
2.sounds like metal on metal on cold starts when temps are below freezing
3.hesitation between 2500-4000rpms
4.sudden drop in gas mileage 2-4mpg

dealers diagnostics
1.struts need to be replaced
2.some sort of carbon seal/bearing that makes the noise upon cold starts, they say its normal and if i wanted it gone they could replace it with a copper one for $1700
3.they said that their is a bad bearing in my transmission that is causing the hesitation and bucking.
4.cold wheather

now I just got off the phone with the dealership this morning because yesterday they gave me a courtesy call asking how my car was doing. I called back today and explained that my car has not been fixed yet because they had to order the parts. Now I'm being told that only my struts are bad and that nothing is wrong with my transmission. I just don't understand how all of a sudden they think my car is fine and it hasnt been in to be fixed? usually this dealer is really good about getting things done right the first time and have taken very good care of me and my car. replacing parts for me for free that are not under warranty.

hopefully we can get to the bottom of this and i can offer some more insight as to what may help you.

Ok so they had my car for almost 3 weeks and came back with it being the Knock Sensor was loose causing vibration and noise there for preventing me from being able to drive my car like I should.
rkreimer if you have any mods on it, thats a common problem for this year. But had the car back for a week and seems to be running like it should!!
Thanks for the Help!!
