B18C Swap Hesitation...
I'm going to explain this to the best of my ability... when my engine is cold it runs like a champ. No hesitation or anything. After a while of driving/warmin the motor up, the motor seems to hesitate frequently when I get on the gas. It will eventually let loose and go... but at first there is ALOT of hesitation. You can feel it holding back... I'll just list the specs of my car, along with mods I did in order to solve the hesiation issue (which obviously didn't work)....
99 Civic EX
96 JDM B18C motor w/ LSD tranny
OBD1 P72 ECU
Replaced:
Fuel pump w/ Walbro 255 pump
Fuel line from filter to rail w/ GSR line.
Brand new altenator and battery... didn't think this would help, but I needed them
And just some more specs in case you are wondering...
I pulled my a/c and power steering(side note)
Replaced spark plugs, rotor and cap.
Also, I replaced the internals of my stock d16y8 distributor with the gsr internals so it would plug righ into my stock harness.
I am running very rich..lot of carbon in the exhaust pipe.
Any ideas?
Thanks!
Matt

Check the timing also, when i did my swap i completely overlooked this. My timing was way retarded, when it was cold it ran like a champ also, when it warmed up anything under 6 grand it was shit. That would be my first guess

I had a similar problem with my swap. I received alot of hesitation, very jerky throttle response unless I gave it a load of gas. It ended up being that my TPS - Throttle Position Sensor was faulty (Might also be called TAS - Throttle Angle Sensor) After replacing that, I had very smooth low rpms. Although, I don't see how running hot/cold has anything to do with that. Could also be that you might have your MAP sensor and TPS hooked up backwards. Check your plugs and let us know.

HMmmm.... I have no idea? I had someone actually drop it in and connect most of the connectors. How can I tell? Where are these two sensors located? Pics are always a big help I can try to swap them. IT does sound like they can be mixed up.
