Hello i have a 2003 toyota tundra about 6 months ago it started to hesitate when i would acclerate from a stop then it would go away as soon as i got going. I bought a can of fuel injector cleaner and ran it through (BG44K) and the problem went away for 6 monthes now it is back and seems to be worse even having trouble idling after starting. It goes away after pushing on the gas a couple times i think its the injector but not sure how to test wich one it is please help it is driving me crazy. p.s. i have replaced the filter and plugs with no change thanks for your time.
