[BROCKDOE]

eyy, jus bought a ECR33 GTST bout a month ago. when i first had it, it would missfire when id hit bout 5,000 revs. but now suddenly it doesnt do it? any one help us out n have ne ideas why? i was told its a fuel cut, n they may have removed it when i got my alarm fitted? but they didnt tell me nething of it.

Covered so many times before. Try the search function, a lot of remedies there.

yeah...sounds like coilpacks...fuel cut wouldn't be at 5000rpm

as keefy said...try the search for misfires

if you want a quick fix! regap ur spark plugs down to something like 0.6, 0.4. i had a bad case of missfire and my gap was at 0.4 and it fixs the problem till i bought some new coils

I was having missfire problems with my R33 when I first bought it (2 weeks ago or so now).

Old mate that sold it to me was using Caltex Vortex (tank was full when he gave me the car).. First thing I did was I replaced the fuel filter and the O2 sensor, for simple general maintenance reasons. He had never changed the fuel filter since he got it. After doing this I filled up with BP Ultimate. I no longer get the missfire problem.. If yours come back you could try that. I'm now getting better fuel economy too, which would more so have to do with the o2 sensor.

Otherwise re-gap spark plugs (or replace, when where they last done?). If the problem is still there, your next step would be coilpacks. They're expensive though, $400-600 for a set.
