Hi when I accelerate my truck itdoesent respond very well I need to push it all the way to he npend so it responds and accelerates more... I changed air filter but still does the same. Any suggestions? Thanks

 

Sounds like you need a tune up

 

plugs wires clean maf all that good stuff

 

what motor do you have?

 

Try a seafoam treatment..search seafoam and read what people have said about it on here

 

I got a 4cyl ranger, I went to mechanic and he said it has nothing... Wierd huh?

 

well its a 4 banger i would not expect much acceleration

 

You probably need a tune up. Spark Plugs, Spark Plug wires and you should also clean your Mass Airflow Sensor and Idle Air Control valve.

 

Yeah me neither but it has gotten to a point that is really doesn't feel normal

 

Sounds like a case of the tune-ups.

 

this definitly. mine barely maintains speed up slight inclines on the highway

 

If your truck is the four cylinder engine, don't expect it to respond very well. It is a small engine on a mid-sized pickup. However, tune up would be the best road to go down:
Check your ignition system (Coil, Plugs, Wires)
Check your fuel system (Fuel pump, injectors, electrical and whatnot)
Check your throttle body (throttle cables can stick or get out of place)
IAC or MAF sensor (cleaning this will prevent the engine from misreading air volume readings and thus improperly mixing fuel off the line)

 

Second word in your title mang, that's why

 

Do a tune up, and also post up a picture of your spark plugs. You can tell a lot about how a motor is running by the spark plug.

 

do the throttle cable mod

 

I am thinking along the lines as motokid as well. You could possibly benefit from doing the zip ties on the throttle cable under your pedal.

Good luck!
