Hello everybody, Jr. in West Texas here, I need some help with my "new" car. I just bought a 1986 GN this past week. Went to get it and never made it home. So much for the "runs good" part on the ad. I figured I could get it to run better after I got it home with the help from people who know these cars in and out. For starters, the car was idling a bit erratic when I picked it up. It ran well enough to carry me for over 250 miles then the problems started. At first, the engine light came on making the engine stall. I was still a good 200 miles from home so I decided to keep going. It then began to sort of die off every now and then. I kept pumping on the gas pedal just keep it running. The engine was guzzling fuel by this time and running like crap plus black smoke was coming out the exhaust. I was trying not to let it backfire by not getting on the gas normally. The car then started to only go about 50mhp and gradually went down to around 10mph until it died 5 miles outside the next town where I parked it then trailered it home the rest of the way(1 week interim).I ran it long enough to get on and off the trailer. At home, I tried to read the codes using the "non-scan" method to no avail. Something kept me from being able to write down the codes because the computer kept reseting itself. All the ECM controlled relays kept clicking on and off including the non-ecm controlled high speed fan relay. I tried looking for a loose connection on all the relays and sensors and trying to see if all the grounding straps were tight. All checked out OK but the wiring harness does have a bunch of taped up wires which I don't even know where they go and they are just loose. There was a clicking appearing to be coming from inside the plenum(dog-house) which I could not figure out what it was. The problem right now is that the ECM won't stay on long enough for me to read the codes. Any ideas? Bad ECM or chip? HELP. The engine light flashes about 3-4 times per second while the ignition is on the "on" position and engine is off--FYI boost gauge shows vacuum when not under acceleration.
----I do not have any regrets on the purchase of my Buick. It is replacing a 1987 Monte SS which I lost in my divorce. Looking forward to driving this machine on a regular basis!! I'm going to enjoy it as much as I can. Thanx in advance y'all!!
