'02 WRX. 80k miles. Engine mods: MBC and ground mod.
I've been having this problem with my car ever since I put in a new battery. I get major power loss when it starts to build boost, and when it does build boost (boost builds slowly btw), the car studders, loses power, boost cuts out sometimes, makes a weird fluttering sound and sometimes makes a sound like it hits the rev limiter when it's obviously not doing so.
Now, this problem only happens SOMETIMES. One day the car will work normally, then the other like crap. It will only change when the car has been turned off then back on, meaning, if the car is working perfectly, while driving the car it won't just suddenly go into this problem I'm having, and vice versa (if the car is runnning crappy, it will run crappy until the next time I turn it off, then back on.)
Now, before we go any further. I have checked my coil packs and they are fine and I changed my spark plugs.
I'm starting to believe that the problem I'm having is either:
A.) The ECU is throwing the car into a limp mode on start up sometimes for whatever reason.
B.) It has something to do with my ground mod that was installed when I had the factory Subaru battery... and now that I have a different battery with a higher cold crank, it's messing something up.
C.) Bad gas, or water in the tank... I highly doubt it though.
After installing the new battery, it also threw a CEL: P1096 (TGV Open Circuit #2). I highly doubt that this could be causing the problem I have since the TGV involves emmissions... but who knows, could it be?
I MUST stress the point that this problem ONLY started to happen AFTER I put a new battery in it. At this point I seriously think it's a battery issue and something is getting messed up on start up sometimes. I'm really considering getting another factory Subaru battery and see what happens.
Pllleeaasse Help! This is so frustrating
