I have a 1989 Toyota pickup with a 22re. 5 speed manual. It has 248,000 miles. Has ran perfectly until now. It does not have an obd port so I have no diagnosis. It started cutting out and sputtering, almost like a dirty carburetor. 

So fat I've replaced the fuel pump, filter, pressure regulator, injectors, spark plugs, wires, MAF, o2 sensor, tps, and drained the tank and put fresh premium gas in it. 

Same problem. It will now start right up and idle, and rev all the way to redline if you go slow, but any fast throttle movement makes it completely stall and almost die. No smell of excess fuel out of the exhaust. All vacuum lines and electrical connections are in great shape. Overall the truck is in phenomenal shape. 

Please help!!
