I can start My honda cold and it drives like a champ. I have replaced the fuel filter plugs and wires cap and rotor. As the car reaches temp the car struggles when u step on the gas if you baby the gas it acclerates ok but as you step on the gas it sputters and shakes??? has anyone had this problem and how do i fix it?????

 

Start with secondary ignition tune up, cap, rotor, plugs and wires, this may just fix you up, it sounds like the spark is jumping from the plug wires inside the spark plug wells.

 

I have allready replaced these items

 

maybe try fuel pump my corolla did that and it was cloged fuel filter bt it might just be not pumping enough gas

 

i had this problem in my civic, was a faulty spark plug wire.

 

check your o2sensor it can be bad and causeing your car to stay in open loop for a while before starting up

 

Its either loosing spark through a leak or its going lean on heavy accelleration, poor fuel supply, my vote is spark. If you can baby it up to 100 MPH then everything is working, just not on a snap throttle or WOT scenario. Have you taken the coil and ignitor to AutoZone for a free testing.

O2 sensors are slow and dont catch up for a second so I would not blame them, the TPS is the updated version of the old accellerator pump on the carb, it sends the signal to tell the injectors to open up on heavy accel, then the O2 catches up to what is happening, they are for fuel control, not initial fuel delivery (instantaneous).
