Hi all,
Long story short my mrs was cleaning her car last saturday and when she tried to take it out of the driveway BAM engine immobiliser warning etc etc. I knew immediately it would be a flat battery so I went to supercheap and grabbed a new century 640cca slapped it in and though nothing else of it.
So the next day the mrs drove it to work and said it felt down on power and stalled when pulling up to lights and when reversing into our driveway. So my immediate thought was a possible boost leak, so I drove it around and notice the bov (50/50 turbosmart)was not active at all unless stepping on it but all I had was a giant dosing falcon.
The mrs then drove it and it went into a low powered limp mode with a cel. First code was a b1318 low voltage and then a boost sensor code p023d(may have been me unplugging the map when having a quick look over the intake).
Just spent the day pulling apart the intake and charge pipes to check for abnormalities, doing the wd40 clean on the boost solenoid and also changing all the spark plugs(really made thinga difficult with the spark plug closest to the firewall socket getting stuck). Done a relearn in and went for a drive. Still have some sh*tty idle when free revving( it drops and comes close to stalling in reverse) and I have 0 boost although still driveable.
I checked the codes and got p1128 wastegate stuck open p0328 boost sensor a high between two drives.
Im a bit lost on what to do but my two main problems are:
1. No boost which I think could indicate the solenoid had sh1t itself or the wiring to the solenoid(im guessing p0328 boost sensor is the solenoid)
2. Idle and stalling which I think may be alternator related I will be using a multimetre to get another readout
As its not my daily I thought everything was hunky dory although the mrs said it was running a bit rough if she didnt let it warm up in the morning and I thought ok fair enough problem just some routine ignition and injector servicing might fix that. I just cant believe a battery faults turned into this lol.
Any helps would be highly appreciated
