Hey guys I’m after a bit of help on a problem i’ve had in the last day.

 

2001 Forester GT

I’ve had a 3” x-force turbo back exhaust installed, and now i’ve developed a pretty nasty hesitation/miss at low revs or when i jab the accelerator. No CEL showing.  

 

Basically, If i give the accelerator any good press from idle, it will stutter for a good half a second before the revs pick up, or if i try and rev match downshift, it will hesitate/miss, sudden rev spike and backfire as i go down a gear. If i press very lightly, it will rev out no problem.

 

Also, I've noticed i'm now idling at around -25in vac whereas i used to be around 20?

 

Other than that, it still revs out fine and drives well. I’ve reset the ECU (By disconnecting battery, pumping breaks and waiting), a few times, but it hasn’t really fixed the issue. 

 

Going through all my hoses today searching for a vacuum leak i found that the BOV gasket wasn’t on properly (I took one bolt off and the gasket fell out), but after fixing that it still isn’t entirely fixed. 

 

Can anyone give any advice on what else to check for before i get it to a mechanic that isn't useless? I’ll clean the MAF sensor tomorrow but i don’t think that is the problem seeing as it came up in one day. 

 

Thanks.

So after a long search, I've finally found my way into a White MY02 GT Forester (Yep, another one)

Completely standard, one owner and in mint condition i couldn't pass it up, and picked it up yesterday morning. 
 

 
 
It didn't stay completely standard for long, on the way home I picked up a new headunit with bluetooth and phone connection, as well as a few other bits and pieces. Installed everything that afternoon when i got home. 
 
 

 

 

 
 
 
Chrome Indicators to remove the egg look in front and back indicators, as well as replacing the parker and licence bulbs with clear white LED's. 
 

 

 

 

 
 
 
This morning I went to the RTA to transfer rego, and decided to ditch the ugly yellow plates for some cleaner slimline white ones. 
 

 
 
 
I'm really happy with the car overall, it was well worth the wait. 

Im planning on sorting out the suspension straight away with a set of coilovers and bigger sway bars. It also needs some tints, and a proper exhaust to replace the pea-shooter it came with.
