Hi all! I'm new here any to the Subaru world! Got my first 1998 turbo 2000 wagon about 2 weeks ago. Since then when I start up from cold the revs hunt from around 850-1500rpm until warm. But then between 2-3k rpm it feels like it's miss firing. The power is still there, but feels like your driving into a strong gusting head wind. It's not always there, but 90% of the time I can feel it.
It's has a big stainless de cat exhaust, front mount intercooler and k&n filter, and some sort of dump valve that only works under high revs.
Any ideas??

 

Unless it has an aftermarket ecu fitted, it has all these mods done and has not been set up for them. Its not surprising its not running right. Really needs mapped for these sort of mods....

 

What he said!!!

 

Cool! Any ideas were or what is the best to do/get?

 

Depends on how much you want to spend and what you want to gain.
You can go down the stand alone simtec type road or piggy back Unichip road the latter is the cheeper and does as good as the stand alone IMHO.

 

I don't think I will be doing anymore mods to it, so just one to smooth out the running issues will do me grand! Anywere in the Cheshire are do them? Cheers!

 

Check the unichip website as they have a where does them section. I have one on mine and a few more mods than yours and it done the job and get better MPG as well. Would well recomend it.

 

Cheers mate. I will look into it and report back

 

try dynamix on here for your mapping needs mate, top guy and knows his stuff, he travels pretty much anywhere
