more of a general question.
the efi I put on my car was on the cheap, when it started to go out, I tried to fix it on the cheap. Relatively speaking.

Some of the failures, are due to the age of the original engine parts.
coil, distributor etc..

Now something else failed and I can't tell what because it is a diy setup, with no real support other than forums.

It could also be some old wiring causing some flaking thing somewhere.

Should this have been a buy once cry once thing? or would I be just as pissed of but spent 3 times as much to get here?
