I have had alot of different awnsers about whats wrong with my truck but still no fix. Its a 99 2wd base. Its all stock besides my air intake but it dosent seem to want get power and go. I can hear my motor wanting to go but it dosent really do anything till I hit 35 and then after I hit 40 or 45 it just slows back down.

Can some one help find a fix or the problem?
