Hello all, Just a quickie. I know the rear coils are different from gtst to gts4/gtr but what about fronts? gtst and gts4 should be the same in the front yeah?

Thanks for your help guys. Had auto sparky here and he sussed it straight away, signal wire for the tps was connected to the shield as well as the wire.... ecu code 55 now Was causing the ecu to kill revs and stall the car. Now running mint again PS: after sorting pcv i noticed the cold start etc piping was hooked up wrong which had a decent hand in the problem.

Might be time for someone that knows what they are doing.... Anyone on the forums know what they are doing and want to make some cash money?? lol..... Have the diagrams here but not 100% sure what im doing when it comes to wiring

checked pins 48, 56 and 57 and all are connected and im getting readings from all. (will have to go recheck for readings) seen about 7 differant diagrams for the 2 tps plugs which has me scratching my head again. I know the switch is hooked up correctly but the other plug im not so sure about, all have been extended for that bloody ffp.... Plug has 3 wires, yellow, WHITE, and black BUT!!! where its joining to the loom (near injectors) its yellow, BROWN, and black (brown is a shield i think, there is a white wire inside it) HELP ME!!!!! lol....... Car really wants to run and does nicely if i keep revs up manually but just wont idle.....

Pin 48 yeah?

Plugged pcv, will hook it all back up with new cooler piping. Have had a go at the screw on the iacv, helped a little. Still getting the tps error..... been stuffing with it all morning with no prevail. In the plug with 3wires I get 5v on one, 0v on the next and nothing on earth obviously and im stuffed if i know why ecu is saying its stuffed. other plug with 2wires im getting 4omns and 0omns on the other wire.

Ok so I have made some progress....kind of.... I have temporarly blocked off minus one breather on the rocker cover and run the pcv, cleaned all coilpacks and regapped plugs, rechecked for vac leaks, cleaned afm, new fuel filter all the usual bits Car now starts clean as but stalls out straight away. I can feed it and keep it alive (sounds wicked, no more fuel smell or smoke) but as soon as i take foot off it stalls, ecu is still giving me code 43 but all voltages are fine on the tps(I do get 12v on one cable tho??)..... checked and reseated the ecu plug and all the pins seem to be in the plug. Could it have something to do with the alarm/immobilisor?? Also I noticed the boost guage sitting on about -20 when i feed it to keep it at idle.... to much yeah???

mmmm..... once my hands better I will be on the tig for a few hours i think.... new cooler piping and AN fittings in the rocker while im at it. going to change it all to AN fittings and do it right (oil catch can+breather, might move pcv while im at it) and yeah the o2 is in the dump, bung you can see is plugged but there is another one with a sensor in it. Start of the green line is the PCV http://s47.photobucket.com/user/placham/media/274010mgvm3mod.jpg.html Its there to stop possitive crank case pressure im pretty sure.

LOL sorry.... to much pvc at work. PCV was some of the problem, noticable differance, now it starts/turns over and stalls straight away, I can baby it at 1000rpm but as soon as foot comes off it stalls. WAY WAY less fuel smell now but a hint still there. Thanks shitloads guys, still getting the error code 43/tps wiring tho.... anyone know of anything else that would cause that to come up? voltages for the tps seem sweet as and has been swapped for known working one.

Thats easy enough then, should be all good. Will block them all bar one and see what that does You guys where spot on, the pvc valve is still in the stock plenum and thats just a open fitting...... going to change it now. Cheers guys

Coming from an sr20 background I have been lookign at the pvc and aac scraching my head actually.....looking at all the treads about these and they just make me scrach my head more lol.... I have a broken hand atm so having trouble pulling it apart so havent gotten to taking the pvc out The whole plenum set up has me scraching my head actually. Been wondering if having ALL vac lines for wastegate etc coming straight out of the plenum might be confusing the ecu a bit? not currently running a bov so no vac in cooler piping only the 3 coming out of the plenum as you can see in pics.... had a little tinker before and pulled aac off and cleaned it (was sooo full of carbon) then set the idle on the side of that which had it running a bee's d!ck better You mean the fitting on the firefall side of the ffp?

Car hasnt been driven with new plenum and turbo set up problem arose after the install. Will do compression test in the next few days

Yeah that was next, have been kind of holding my breath hoping there isnt bits of ring in my sump....... Thanks mate, will post what I find out

Maybe head gasket then??........ Smells very very fuelie tho, like its running super rich

Hello all, I have scored another 32moredoor gts4(scored it mega cheap...), when I bought it the engine had been played with. Has had FFP and topmount td06-20g-external gate installed, fmic, stock injectors, stock coilpacks, stock afm(green label), stock ecu(still untuned after installs). I have seen the car running before all installs and it was mint. Has also had alarm/immobiliser and switch to disengage the front diff installed (have herd of immobiliser screwing with some cars) On cold start I have to feed it to get it to start and idle which it only just does, once running it struggles to run, misses like crazy(sounds like a rough subaru) and overfuels(can smell it) sits on about 500rpm then stalls out. Ecu is telling me code 43 but I have had multimeter on the TPS wiring and all is good voltage wise but nothing changes when its running and I disconnect the plugs on the side. Has been swapped out for a known working tps and same problem. Didnt think a turbo and plenum swap would throw everything out so much??? Blows a bit of white smoke which im guessing is fuel. Havent kept it alive long enough to get warm incase its something major. All the coilpacks are fine and plugs seem to be ok aswell, swapped out ignitor and no change Also there is NO change in idle etc when I unplug the AAC etc... I have looked into most things and am about to send it to a shop but would rather save the $$$ for when I get nistune/afm/injectors/TUNE but dont want to do all that and find out the motor is ROOTED!!!! I attached a before and after of the engine, did a massive tidy up/clean while trying to find the root of the problem, has all new vac lines etc now. Can upload a video of it trying to run if that may help.
