Just took the car out to see if its behaving itself tonight and to do all the diagnostic checks, all the checks say its ok but it blatantly isnt 
This is a bit of an essay im affraid but it is a comprehensive list of my problems.
Here is a list of my problems, some may be related to each other, some not, but I really would appreciate any help as I as tres p****d off with it.
Firstly a bit of background info. I bought the car just under two weeks ago, seemed tip top on the test drive, took a mechanic with me to check it out ( he drives a civic turbo! ). On getting it back the first thing i found was an incorrectly fitted boost controller. A Blitz dual SBC. The sollenoid had been fitted in series with the standard one! A well known UK tuner is responsible for this but no names mentioned. Driving was ok off boost or on full boost (0.95bar) but anywhere in between it made some really odd noises from the wastegate, then had a really sudden cut in boost to 0.7 bar. This would not reset without stopping the car and turning the engine off.
Anyway so I fitted the sollenoid correctly as per the instructions and set it to a gain of 5 and duty cycle of 50 for the high boost setting. Seemed fine for about two or three days, with a fair amount of driving. But on thursday afternoon I took my mate to get his car, it was perfect one second then like a switch nothing, all performance gone. It still comes on boost the same and registers the same but its just dead slow!!!
This is where my real fault finding started. Firstly did a compression test, results as follows;-
1, 7.7, 112 (front)
2, 7.6, 111
3, 7.6, 100
4, 7.5, 109
5, 7.6, 110
6, 7.6, 110
Cant remember the units hence why i have put the results from both scales. To me this seemed fine. The tuner mentioned earlier also fitted a set of HKS plugs which were in WAY to tight! But these looked ok ish.
So I put it back together and took it out again. It runs beautifully off boost but try to bring it on boost and it sounds really raw and 'angry'! Not at all smooth like it used to be. Tried with the boost controller off so it was at 0.5-0.6 and it was a tiny bit better but not right.
Anyway today I had to drive about 150 miles to my parents house (mums birthday!) and it was hideous. really did not sound healthy with any boost at all, but sweet as off boost!? Further more it has started to just cut out whilt driving, just dies nd coasts for about a second then comes back to life. This has been getting worse through the day, I struggled to do the half mile to a car park just now!! Did the diagnostics thing, fine! reset the ecu. Still does it. Tried to bring it on boost and it almost stopped dead in the road.
Anyway on to the other possibly unrelated problems;-
Tempremental oil pressure guage. It keeps on just falling off to zero (scared the s*** out of me when it first happened!) I havnt actually lost pressure though asthe warning light doesnt come on, and i know this works. Reset by stopping and turning the car off.
4wd light comes on after hard accelerating through 1st and 2nd (when I could!). Lights up just as you go into 3rd. Reset in the same way.
Lights flicker, Battery voltage guage has negative spikes which are very short and sharp but noticable. Occurs when changing throttle angle ie 0% to slightly open or held at constant speed to off. Happens most of the time, I saw the lights doing this straight away but only noticed the guage at the begining of the week.
I dont really dont know where to go now, Ive had it sugested to me that the alternator regulator rectifier unit could be partly to blame but appart from that no ideas. It has to be something electrical surely? Even if someone knows somewhere who has ealt with simillar problems before I would be gratefull.
Like I said any help at all would be very welcome. I have two other concerns, one is that my fixing buget is not very big considering how much ive just spent on the car, the second is that Im being sent to the Gulf in a couple of weeks time (I think you can guess what I do for a living from that!), so I need to sort it sooner rather than later.
Sorry this was so long
