My truck starts up and runs like a top. the next day i go to start it and it will ( buck) when it starts it will idle fine but if you touch the throttle it will run very rough, i have no check engine lights lighting up, i took it to the local garage and 11 days later they say their is no problem with it.
i drove it home ( ran very good ) the next day it acted like the battery was week and it bucked again, idle is great but will not run when i give it gas, PLEASE help me with this 4 month old problem.. jim
