haha so I found out something interesting, ok so my tachometer in my 87 V8 GT ...USED to work...
however now what it does is when I'm at about 3k it will suddenly jump from 1k to 3.5 or so and keep going lol
however I noticed something that might be a clue as to the problem
when I start the car the needle will force it self downwards (meaning away from the numbers)
also when the car is on....if I open a window in any direction....the needle will force it self downwards as well
now I did electrical for awhile....but I have no clue as to the circuit going on back there...would this be a grounding problem or a possible short??
I can't really tell
oh if it helps any... my fuel gauge is always full?? until I have like no gas left and then it's suddenly almost empty (but my gas light still works thank god lol)
