Odd problem.

Fuel line mod has been done,car has been rewired. It has hei ignition and my last tune up has been a while so ill pull the plugs today and check. I do drive alot before i got the car from my uncle that passed away i convinced my wife (we were looking for a second car at the time) that i could put a couple of grand in the car and we wouldnt have a payment. So i put about 35000 miles on the car in the last three years just driving it.
