Problem is constant now but it was intermittent and would switch after a few minutes.
My engine sputtered just a little then it started bogging down on me. It would shift through 3 gears but is pulling very hard now won't move at all.

An excellent vehicle with some previous owner issues - such as no oil changes, lights not replaced or repaired, fuel inlet restrictor damaged/missing, missing sound system but intact radio/cassette player, and otherwise shoddy repairs to the whole of the vehicle. But, as with any gem in the rough, this vehicle has a great engine and transmission with low (for the year) miles.
