The original engine had 89K miles when it spun a bearing. The car sat for 7 years, and then, I installed a rebuilt long block, reused the original intake including all the sensors,
I did install a new O2 sensor, replaced the fuel tank, fuel pump, fuel filter.

now I get the following codes:
15, 21, 25, 13, 14....anyone know what combined problem this could be.

I'm pretty confident it's not all of them, but a single issue popping up that list of codes. I'll be rechecking.. (for the 5th time) my electical and vaccum connections.

I cannot find an accurate (clear) proceedure for setting the timing. So I have it set by ear right now. but not matter wou much I adjust, the idle it never totally smooth.

Could be a ground?

Any other ideas would be great.


Thanks,
Chris
