hey guys I have a 82 Toyota pickup sr5 22r first off the engine sputters but only randomly it did it on the freeway on a crawl trail in upper elevation and in a riverbed so its random places I replace the spark plugs the wires and the distributer also replace all vacuum lines. would it be better to just do an engine swap if so to which should I go 3 liter ? or just keep the old 22r and just rebuild it

 

What 3 liter would you go to?

 

The 3.4 5rz

 

Take your air cleaner off, crank the truck up, and while opening the throttle spray ether in there.
