5 grand problem

[noise]

Hey guys,

when my 2k GTT came in off the boat it was not firing on 4th cyl, so i replaced the plugs with some iridiums which seemed to fix any problems.

Sometimes but not very often when I hit 5 grand in second gear, maybe other times too, it seems to lose power. It kind of feels like its not getting enough fuel to the engine or something.

Someone has suggested fuel pump an other the air flow sensor?

any ideas?

knock sensors. i have been through 3 sets of knock sensors in my rb20. there is a simple test, while driving your car, rev it over 5k in 1st then try it in second if it wont revover 5k turn the engine off whilst still moving, (do this on a strait rd not on a bend) then restart and rev it in second past 5k then into 3rd if the problem reoccours then its knock sensors.

same thing happened to me when i first got my car.. 9 months later it came to be the knock sensor. just check they are connected

Is it running standard boost pressure?

Thanks for the replies guys

I will get the knock sensors checked, my mate has the diagnostic computer thingy at his workshop so it should be easy.

Yeah it is running stock boost.

we went out on friday night i think it was driving around with the computer plugged in, and of course it didnt do the thing we were trying to test for.

again tonight I drove it and it didnt do it at all, yet it did it today.

I have a feeling its not doing it in the much colder winter night air.

any ideas?

will have to take it for another spin during the day with the computer... just hard to find the time.
