Cold Start Problem

[Ruffels]

I tried searching, but my problem seems a little different to other peope who have had cold start issues

in the morning when its cold, and the car is dead cold too the car will start fine, but unless i wait 2 minutes for the temp to rise, the car doesnt like revving or driving

as i said, car will start fine and idle fine, but if i go anywhere near the accelerator, its just coughs and splutters and even stalls sometimes

details:

97' R33 gts-t manual

pfc, z32 afm, 555cc injectors, bigger turbo, fmic, 3" exhaust, 040 pump, splitfire coils

I have the SAME PROBLEM!

I was told it was AFMs, will let you know if this solves it.

I never drive any of my Skylines until the water temp starts to move and have no problems as a result.

They just do not like to be driven when they are cold.

umm.... i disagree.. ive driven many skylines including this one from cold for YEARS, no problems... how else am i going to get everything (gearbox, diff etc)up to temperature - i dont thrash them when cold, just get them moving nice and slowly

this problem has just arisen over the last few weeks

i am assuming you have the pfc programmed to take over all of the original computers controls and removed the old computer? if so maybe your ECU water temp sensor is feeding the pfc dodgy info? as the pfc would not have a default map to revert to like the skyline computer does? could be worth a try testing it by swapping with a mates?
