Finally a fault code



Here we go...1981 all original with 50k original. Been sitting about six years. I bought this year. Just rebuilt brakes all around and changed fluids. Runs great until she gets up to operating temp and .....sometimes...... it starts to bogg down under acceleration. Been thinking it is an ICM and have a new one that will go on tomorrow to see. Tonight though a new twist. I got code 44. Lean exhaust. My gut says it may be a vacuum problem because headlights are not working and tonight the air diverter in dash would not bring air off floor. Code says lean so ?????
Thanks in advance
