91exAccord Stumbles when accelerating warm

[eidsvik]

Hey Gang,
90 Accord ex 4dr 5sp 95k on 2nd engine

Start it cold runs fine at idle and driving. As soon as it's warm it begins to hesitate/stumble hard from a stop into acceleration. I can give it a bunch of pedal and ease the clutch out to get it moving from a stand still and minimize this problem. This problem developed from a light version of what I described, to this over a 3 month period. Problem used to only be around town, now on the freeway I give it gas and it stumbles constantly unitl I get it up to a constant speed then it stops.

At warm idle has a bit of a miss or it stumbles down a bit. Mostly stays constant. Seems it appears only when I'm requesting some low end torque.

I have:

-replaced the ignitor/coil/cap/rotor
-replaced the fuel filter
-replaced pcv valve
-followed my haynes manual on checking the EGR valve all seems to be in check
-disconnected the vaccuum line from EGR to see if idle improves -nothing
-codes for my speed sensor only. (cuz it's out)

Anything common I'm missing?

Thanks alot.

-Jason

Check the MAP sensor and hose.

you may want to check the temperature sensor and wiring. (honda calls it the tw sensor)
