Today I'm going to replace my aac valve and air regulator I've replaced all the plugs, igniter, loom and coil packs. I found yesterday my fuel line before the filter was swollen and had a leak so I replaced that.

I was driving my car and on full it was only getting 30-40 psi oil pressure but since advancing the timing it's gone back to what it should be. I got it so it does just rev of its head but now it's got a hunting problem but doesn't have any leaks. It's like the car revs to 3k and then dies and when it's about 600-1200 it starts again I tested a known working maf the same way and it didn't have 12v on the signal it had 300mv like there meant to
-
Ignition on and from maf pins to earth
-
I just tested my air flow sensor and I had 2- 10.5v 3- 11.5v 4- 11.5v 5- 0v
-
I did find a vacuum leak so fixed it and started the car and it didn't hunt but idled high, I did notice just before that the sensor in the radiator wasn't connect, is it used for anything?
-
I did pressure test it the other day and found leaking injector insulators but fixed that, I'll do I pressure test tomorrow and report back. I got it close but when I took it for a drive it boosted up high but felt like it wasn't doing anything so we advanced the timing a little and it went a lot better and it also helped with a oil pressure problem I had
-
I had my car running good today, went for a drive and my car just started reving high on idle so I drove home, and stared it at home now I an idle hunt goes from 1000 to 3-4000 what are the main cause of idle hunt?
-
And I'll pressurise the ic piping and test for leaks
-
Yeah I had it all the way in and I thought it should almost stall, I'll put a known working one properly
-
Yeah had it loose and had the aac valve all the way in too
-
I having trouble getting it to idle at 650 the lowest I can get is 800
-
So it's meant to be 15° btc And the rpm is meant to be 650? And do I need a loop wire or is using the wire on the coil pack plug good enough?
-
After work I'll go check all the marks again and test it and post the result
-
Yeah I've checked it so many times, do you have to disconnect the vct solenoid as well?
-
I'm using the stock ecu.
