Ok, just encounted a prob with my n/a RB30. Cruising down the highway and it feels like it misses, then regains and a short while later misses again. Is intermittent and wondering if its the fuel pump?? I have done a service recently and no change . . . Could it be the fuel pump or something else? Idle is good, Revving up to speed is good, just cruising it misses occaisionaly, feels like its dying for a second)

Check leads,spark plugs,dizzy cap,rotor button,and see if there are any lose connections...Also the ECU might have encounted some water in it which is why your car is missing...

man mine was doing the same thing,mine was a faulty connection, have your car running and just wiggle all the connections , like all the cas ones and stuff might be the same as mine... mine did it for a while then stopped.. and just started doing it again. i think ill take it to a auto lecy and get them to chuck new ones on.

Cheers, I think ill check the connections, maybe pull em all out one at a time and give them a spray with cleaner then some inox. See how that works then check the fuel pumps . . .

o2 sensor or afm or many things.. Do the cheap and easy things first. If it still happens get it diagnosed properly
