I've replaced the Throttle Position Sensor, the distributor cap/wires, and the fuel filter. It still Boggs down every time I press the gas pedal going down the road. It idles fine, but the engine starts dying when I put a lot if pressure on the gas pedal. Any suggestions? Could it be the fuel pump? Or incorrect calibration of the throttle position sensor?

 

There's a lot of stuff it could be. Any codes?

 

Haven't gotten a code reader yet, but probably am today

 

I haven't got a code reader yet but will have one soon. I think it's the fuel pump, but im unsure. It only Boggs down when I push the pedal down hard, but hoes just fine when I ease it down. I'm stumped.

 

You can test without a code reader for free. There is a sticky on the 87-96 page.

 

Fuel pump.
