I have the details of the mods, but have questions: Is the jumper wire (part #318 6890) just a wire or does it contain a diode or resistor of some sort? If so, where can I get one? Next Q: the "Vehicle Emission Control Information Update Label"
(part# 8983 100 009) seems like the proverbial needle in a haystack. I can't find one. Can someone with a High Altitude adjusted wagon send me a pic of the label? I can have it reproduced. I should be getting my "new" '87 Limited shortly after the New Year from Pennsylvania. Any help greatly appreciated. :amc:
I've spent ALL DAY looking on the www for this. You're now officially my best friend! :amc:
Nice info!
Looks from this that if one were to drive a high altitude emissions car at lower elevations, mid grade if not premium fuel may be a good idea (assuming all is at spec, of course) until the adjustments are made with the 7˚ further advanced timing spec'd for >4000' operation?
I'm asking since I'm headed to Denver for work this weekend, and there's a drivable '87 on CL in CO Springs... I have nearly no free time, but it's the most promising lead I've had yet if I can make something work out.
Thanks.
I think putting a relay in with a toggle switch for high/low altitude would be extremely easy
That would take care of the electronic part, but there's a vacuum line swap and a 7˚ static timing difference as well if you read through the bulletin. That's on the slush boxes, I think the 5 speeds have a few more changes than that, even.
There are vacuum solenoids too. I use one to shut off the vac advance on my truck when I'm towing and it starts to ping.
