Hey all,

I have a 2007 WRX with an Auto. At freeway speeds after doing like a constant 60-65 it feels like it has an intermittent miss. But my friend drove it with with a scan tool and when it did it, it didn't recognize a miss and it sounded like the engine was running fine. So we think it might be a torque converter lock up issue? I had one other instance from a 4 way stop where a car waived me on and I tried to accelerate and it just fell on its face. Like it went into limp mode until it finally took off. No codes or CEL have come on. Any ideas?

I should mention. I just got the car about a month ago. Only mods are a Subaru cold air intake and catback exhaust. I've read a million times to get rid of the Cold Air and I think it may have had a boost controller as there is a random wire coming from the firewall coming out of a little black box that goes to a check valve and vacuum line. I bought it from a Subaru dealer so I wasn't able to have contact with the previous owner.
