dude, get to a parts store and but a book for your truck, about $10-$15 it will have the procedure for getting the codes, its easy to do
under your hood near the coil; you should find a electrical plug with a rubber cap mind terminals T and E1, use a peice of wire and jump between them
turn the key on and count the engine light blinks to get your codes for a code 7 you will get 7 blinks then a 5 second pause then another 7 blinks, if you have more than one code, and you will there will be a 5 second pause between them, for codes over 10 you will get blinks ,a short pause and more blinks, then your 5 second pause befor the next code
i'll bet you need a throttle position sensor, code 7
