    Delco-Bose StereoTuner Issue

    some time ago my radio/tape player went out on my truck, which was about twice as tall as standard radios. Bought a new unit at Best Buy, much better radio than what was available in the early 90's. The installation kit had a front mounting plate which filled the extra space. BTW an antenna will...

    What Octane

    Yes I got the answer, I will be running 87. The sort of referenced that today's "fuel injection" is an injector per piston. The 1984 Xfire just "injects" fuel in the intake manifold. A bit more than carburetor, but short of full fuel injection.

    Fast idle and hard starting cold 1984

    Hi all; 1984 Here is my next fault to fix. Actually this problem popped up after repairing broken wire going to temperature sensor (gauge was reading 299 F), so my first thought was maybe I knocked something loose, but haven't found it yet. Engine turning over but not starting when cold. Poured...

    Whatw is this wire hanging from under dash

    Thanks to posters. I figured it out by your suggestions. It is the "Clutch Safety Switch" circuit. I will need to further diagnose to find out why it is disconnected. Probably the switch or as suggested switch adjustment. REMINDER TO SELF make sure shift in neutral until fixed!

You can build a test cable (or buy one from him) and do some of your own diagnostics, then purchase the parts from him. Seems the number one problem with...

    What Octane

    Thanks to all that replied. Since my car is designed for 87 Octane that is what I will run in it once I get it back to road worthy status (bought a project car). I am basing my decision on technical facts that the compression, timing etc for MY car is designed for the 87. As an interesting side...

    What Octane

    1984 crossfire fuel injection (sort of) I assume the proper gas for this year is 87 Octane. Don't have the owners manual and the service manual does not seem to address this issue. Comments please

    Electrical issues 1984

    Fixed Don't know how to delete this thread I just started, especially when you see the fix I found. Started to remove the wood face off the dash and ended up causing the round knob, which I assumed was just a intensity knob for the dash lights, move out. Heard the headlights flip up and come...
