Please read - Advice needed. MY02 WRX
Hi all..
I`ve had my MY02 WRX PPP for 4 years now and I`m having a lot of problems.
I have defiantly lost a lot of power....
After about 30,000 miles my car would hesitate while on full boost, then it would hesitate while under load i.e climbing a hill, now at 80,000 miles its doing it either just before the turbo kicks in and while in boost conditions, and also I have the problem when I`m on the overrun comming down a hill in 4th or 5th gear using engine as braking the car jumps a bit when the revs come down below 2,000RPM.
I should add that the hesitation is not major, just realy annoying.
If I accelerate from a standing start. i.e from a roundabout I get an initial misfire, then the car will pick up.
I had PPP installed before xmas last year, but again initialy the change was massive, now its back to what feels like standard, if not less...
I have installed: Magnex cat back system, PPP... Thats it.. No major mods.
So far I have recently replacedIn the last month or so)
1)Both front and back 02 sensors. This did make a differece, but now back to the same old ways..
2)MAF sensor.. As above, same inital change..
3)4 Plugs
4)4 new coils.
5)Prodrive fuel pump.
A strange thing happend the other day too.. While driving at 60 I was trying to get the car to hesitiate.. When it did, I blipped the throttle and the car ground to a halt. No ECU lights or nothing! Car just rolled to a stop engine stopped and usual lights came on.... I switched off the ignition and then restarted the car.. It started with no problems at all.. That was the first time it had ever done that.
I`m not getting any smoke out the exhaust either..
As I live in Shetland my local dealer does not know what to do, so I`m pretty stuck.. I use deltadash, but even that is not showing anything other than my car only ever getting a max of 1 Bar boost.
I noticed when I had the car in the garage, that when I turned on the ignition (Not start)the fuel pump kicked in as it does, there was a strange liquid flowing noise comming from underneath the air intake pipe as if there was liquid passing somthing at a high pressure until the pump cut out... Would this be a faulty injector????
One problem I have up here is that I do not have SUL only unleaded.. I use a bottle of millers octane plus on every fill..
The most annoying thing is that somtimes the car will go like a rocket, then it dies..
I`m realy pulling my hair out so any advice will be much appriciated.
Regards
Gary.

It did do it prior to PPP. What I can`t work out is why somtimes the car runs okay, then not. It seems to happen in a kinda fixed routine. Run fine for a couple of days then return to crap perfoamnce, then a couple of days later fairly normal.
I do have some DD files if you want them..
