got a bit of a weird fault can anyone throw some light?
ok so the engine is an S15 SR.
From cold and allow the engine to warm gradually by driving slowly and after 20 mins of driving (slowly) if i suddenly put my foot down it'll splutter, lose power sound like its running on 3 cylinders i then lift off and coast for a few seconds and put my foot down again its absolutely fine.
i regularly go to a local jap meet, when at the end of the night means pulling out on to a busy road and having to put your foot down.
This happens EVERY time, i pull out and it splutters as outlined as above, again lift off or slow down its absolutely fine.
now the last time i went, we arrived with no issues (after a spirited drive) whatsoever parked up went inside for a drink came out maybe 2hrs later, started the car and sat there for around 15-20 mins chatting, so the engine was warm, again pulled out same thing happened.
the only thing i can think of is could a dodgy coolant temp sensor cause the effects above?
what i have noticed this doesn't happen if after 15 from cold (to allow coming up to temp) i kinda gradually allow boost to build for the first time the above doesn't happen
