You still alive GBGN1? I found a red brick and it works great - much easier to set TPS for example.

When I turn on my headlights or even just parking lights; the RPM and Boost LEDs go out along with the radio display and dash illumination peanut bulbs. Mkes it tough to drve at night not knowing how fast I am going. Dimmer still seems to function as floor illumination lights are good. I...

I searched the forum to see if anyone recommended a company that would re-manufacture ECMs and MAFs and didn't find any. Does anyone know of a company I can send used ECMs and MAFs to, to have them checked and or re-manufactured? I have three spare used ECMs and I suspect at least one needs...

The nut in the clamp that connects to the MAF has spin and broken the plastic clamp (attached). Any thought on where I can find a replace,emnt. Right now Gorilla tape is working.

How many wires should come out of the bottom of the steering column and what should they do? I know the one that is a PITA to fish in if you have attached a guide string, is the cruise control/delay wiper wire. Should there be any others??

1984 GN posting here to reach as many owners as possible. my car has been in a local shop here in Canada for a month. I am beginning to think something has gone drastically wrong. I may be facing a tough time to get the job done or to have two the car to someone who knows what he is doing...

So here we are in Florida with very few tools and I just bumped into a no start condition. After the WOT bogging down situation solved with a used coil pac/ignition module and the car was running better than ever for about a month, last night I go start it and no go. There is fuel at the fuel...

I am looking to buy a known to work, ignition control module for a 1984 or 85 Grand National (the piece directly below the coil pac). It may be attached to the coil pac or not, as long as it was working when removed from the car. If you have a used one or NOS or know of a supplier please pm me...
