97 LTD, hard to start when is warm

[majm]

Hi,
My 97 LTD don't start itself when the motor is warm, I need to accelerate because the acceleration feels low. Somebody can tell me what to do?

[vandok13]

Can you explain a bit better and a bit clearer? its hard to understand what your asking

[majm]

The 4 runner works correctly but after one hour of use feels that the acceleration of the motor is low and if I turn off the motor and turn on again, the car can't start on because seems that it doesn't receive fuel and I need to push the accelerator pedal.
I hope this can be clearer.
Thanks

How many miles since your last tune up?

[majm]

Around 5,000 miles from the last tune up.

Have you changed your fuel filter lately? What about your check engine light, is it on?

[majm]

Yes, I alredy change the fuel filter, and the check engine light is off.

Well what I would try is after the engine is warm I would pull one of the plugs and have someone crank it over, look to see what kind of spark you are getting. If your getting a good spark then I would check your fuel pressure. If its good then I would check your tempeture sensor. Just process of elimination. Hope this helps.

many of these types of problems are usually related to the idle air control valve
