Hi All,
I've a problem with my 90 Auto with 150k klms. Perhaps some listers can offer some suggestions.
I was on a long trip, did 900 klms on day 1.
Occasionally the engine would hesitate a little bit. Sometimes this was due to the TCS system when the light would come on but this has been happening for years (perhaps because I run 17in/18in with the next model tyre sizes). (De-activating the TCS makes no difference, the orange light will still come on). Occasionally when it hesitated I noticed a flicker in the tach needle indicating an electrical problem. Slowing down and blasting up to C150kph was faultless.
On day 2 it got 40 klms and cut out altogether and wouldn't restart although it turned over vigorously. Eventually it did but stopped again shortly later. I put hazard lights on and left it. Service man came and by then the battery was flat. We jumped started it and I drove a shorter distance and it stopped. Got it to a country QLD dealer (never seen an NSX before) who tried to trace the problem unsuccessfully. They think it is an immobilizer, which was one of my suggestions. There were also faults connected to the TCS and Transmission recorded although I'm not certain they had all the right diagnostic plugs.
I think I'll retrieve the car by trailer next week but would appreciate any suggestions in the following areas:
Through my stupidity and paranoid insurance companies it has had several iterations of alarms, the factory one and 2 at the insistence of the insurance companies plus the Sat tracker.
1. Factory alarm with 2 buttons working the central locking etc..
2. A Moss security MS735. (on reflection this could be the above as it has no separate interface).
3. A Brant Transponder proximity engine immobliser.
4. A Black Widow/ Car Watch satellite tracker including "Start Inhibitor".
Working on the basis this is the problem I'd like to start by removing or total disabling all these then installing a new device. In particular where does the immobilization occur? The Moss booklet says "Preventing starter motor operation, what about the others?
I imagine there a few $2.00 relays which open or close circuits. where would these be found and if they failed would they be in run or disable mode?
What does the TCS operate to partially shut down the engine and is this possibly failing due to overuse?
Are there any other suspect components with a history of these types of faults?
Would a weak battery have anything to do this while running? Probably when it cut right out it was doing <2000rpm but it always turned over well.
Who in NSW would be qualified and equipped to look at this? So far it has never been to anything but a dealer (I've had it from new), last time Sports Honda at Petersham but they didn't really know the car.
Any assistance will be really appreciated,
Thanks,
Gos
