Ok so my 86 grand national has had this problem ever since i got it running in 2010. I have to unplug the ac plug up near the bottom of the windshield (passenger side) because if i dont, some kind of fan will continuously run even when the car is not running. The interior AC only works when...

On my way to work at 6:30 this morning my scanmaster was working normally. But when i was leaving, i started the car and saw that my scanmaster isnt working. It's not lighting up or anything. When i got home, i checked to make sure everything was still connected and plugged in and everything...

Hey guys, I mounted a vdo boost gauge on my a pillar and it works great. But I just have one problem, I have no idea how to make it light up. The kit I bought did not come with any parts to do this. If someone could give me a step by step procedure it would be much appreciated.

I have my haynes book with me and it says to disconnect the negative battery cable, then remove the two attaching screws in the top inside of the fender. I cannot find the two attaching screws that they are talking about. I mistakingly took out the two hood hinge screws and the hood fell. I...

My antenna is stuck in the up position on my 86gn. I actually have to unplug the antenna at the connector under the hood because if i dont, the motor will run nonstop. When my radio is on, and the antenna is plugged in, the motor does not run. But when i shut the car off, or turn the radio...

I am thinking about installing a new maf pipe to replace my stock ribbed cloth pipe running in between the maf sensor and the turbo. I would buy the new pipe and get a k and n filter to attach to the maf sensor and get rid of the whole air box assembly. My question is, where would the air temp...

Just wanted to see how many of you on here went ahead and got the windows tinted on your cars. I think that my 86gn would look good with 20% tint but others have told me that classic cars shouldnt be tinted. Any advice?

Just a quick question. My car is an 86 and has the original catalytic convertor on it still. My car runs pretty hot (in the 200's most of the time). I am going to have the radiator flushed, and am going to install a new thermostat asap. 1.) Would a clogged or bad cat also contribute to my...

I have a stock 86 gn. When idling warmed up i'm reading about 30 lbs on my fuel pressure gauge with the vacuum line on. My question is, when i remove the vacuum line from the regulator, should the fuel pressure IMMEDIATLY jump to 38-39 lbs or does it take a while? I have to wait about 5 to 10...

I have everything hooked up and with the instructions that came with the translator box, it says to make sure that the pink wire on the translator box lines up with the pink wire on the maf connector or damage can result. But when plugged in, the pink wire on the translator connector can only...

My car has a scanmaster installed, and under wide open throttle the O2 readings say 003 and the AirFlow reading (AF) says only 91. I have heard that the AF reading is supposed to hit 255 under WOT. Would this indicate that my maf sensor needs to replaced? thanks for any help

Does anyone have any pictures of how a walbro 255 fuel pump should be installed? Thanks alot for any help

i have a 1986 grand national with 164,000 miles on it. it still has the original catalytic convertor installed. Would you have reason to believe that this cat may have gone bad due to the amount of miles that are on the car. Also, my car sputters and backfires under wide open throttle, would...

i have a 1986 grand national with 164,000 miles. It has the original catalytic convertor still on it. In your opinion, is there reason to believe that it could be clogged with that many miles on the car? and if so, could a clogged cat have something to do with my sputtering and backfiring...
