Default 94 Toyota Tacoma, 4x4, V6 fuel injector, help?
Runs smooth but very in power, at first start it seem to take bit before fully engaging.















Some times, lots of power and shifts well, other times it seems weak and will not sift to the high gear unless, excessive acceleration is applied, good on fuel, then bad on fuel, but aways run smooth when idling.















Is it fuel pump, bad injector ? I have new wires, plugs etc., transmission rebuilt.































Why does it run great with lots of power at times and runs smooth at other times but weak in power ?

Did some research:































Could be 02 sensors (same on a Chevy Malibu) Pepboys here in Jacksonville will do both of them (suggested) for $275 installed probably 3x that at Toyota dealership















Air Filter















Fuel pump will effect something like this but when that really goes you'll know it...truck will stall and die (stall and die -- also with 02 sensor or sensors going bad)















Injector is fixed with 02 sensors -- ask them to look at?















Fuel is not what Toyota says it is compared to sites I just visited on your truck















































The acceleration issue running good than maybe not sure sounds like 02 sensors for sure...































You might want to spend the assessment charges first at Pepboys or Toyota and see what's going on with the whole thing? It's like paying for a medical doctor...































Good luck.
