My 85 4runner will start up right away but it has no power, it idles around 400 rpm. When I push on the gas the rpms rise slowly. I gave it a tune up and replaced o2 sensor, mass air meter, throttle posion sensor and checked to see if there was a vacuum leak. Satill runs the same. What could the problem be?

Check for an excessive backpressure in the exhaust system to rule out the catalytic converter and also the fuel pressure
