Hi Guys.............another long one but pls bear with me
Just thought I'd give an update. The very rough idle is still bloody there. It does drive smooth as though.
Listed below what I have done thus far
and welcome any further suggestions. In a kind of weird way i enjoy the challenge of working out what the
problem is, even if it's driving me up the wall. I have bought the Gregorys manual.
Error Codes -
I received codes for the first time the other day, 22 & 23, relating to TPS and Air temp sensor. Cleared them and haven't received the errors since. I am replacing the ATS tonight.........the TPS is $170 from Holden!
Replaced so far with new genuine parts -
Fuel pump, fuel filter, CrankAS, CamAS, IAC, temp sensor and temp ECU sender, Fuel pressure regulator,
o2 sensors, new leads, checked plugs,injectors professionally cleaned,
Checked and or Cleaned -
removed manifold and plenum, cleaned inside out with new gaskets.
removed and cleaned Coil packs and checked resistance, engine mounts(mechanic told me they are ok but do I trust him?),
Harmonic balance feels and looks strong, ie, no play or wobble.
Chcked manifold purge hoses, swapped them around at the purge solenoid in case they need to be in some
order? One goes to the TB the other to the canister.
Removed and cleaned the starter motor and contacts, was black as but now starts beautifully!
Still to Check -
Cylinder Compression ?
Remove and clean the DFI (have removed and cleaned the coil packs and resistance ok) ?
ECU ?
May take the tank(ute) back out as one of the vapour hoses running from top of tank to the bottom near the return hose wasn't connected.......assuming this needs to connect to the canister vapour hose coming from the
canister in the engine bay?
anything else I am missing ?
