92 bronco is getting very tired HELP

Hi

My 92 bronco has lost much power. It sometimes back fires, a bogs out like there is no gas. It is fuel injected 351.
Can the throtle position sensor do this. It also hesitates when the throtle is open about the same distance and it would be for normal driving. This problem started after it sat for about 30 days.

I am going to change the throtle position sensor and hope for the best at this point in time.

It past the emission test oK last fall.Also there are no fault codes comming up.

It starts great , idles great.


thanks
Doug

I would start with a tune up and check the timing.

Also, you might have some injectors clogged. You might try some injector cleaner to run through with the fuel. Replace your fuel filter and air filter.

check fuel pressure too. Your fuel pump may be going out.

I was also going to say fuel pump. That deff sounds like the fuel pump going bad.
