Make some sort of sense actually caused i happened to get crashed from behind not long ago.. cheers man.. But the it actually (TCS off) lights that came on, so i assume that TCS is already off when that happens..I see that the computer actually slow me down, but by lowering the sensitivity of the gas pedal? , cause when the problem happens, the car wont accelerate the way it should be, and when i tried to boot the pedal harder, the car still revving but definately vibrate way more (i mean like way2 more) but no acceleration..
Anyway man ur such a help, will tell the mechanics to check the exhaust system for sure!!
anyone else have any other idea, the thing is i want to get as many idea as i could from u guys, last time i went to get it serviced, DUA charged me the extra hours but the results is none (wasnt very happy )!! dont want that to happen twice..
Hey mate, I live in New Zealand and I have an R34 GTT. I am 100% sure that your problem is coil packs. I had this same problem. The car sounds more like a subaru than a skyline right?
If you leave it then over time the problem will get worse and worse and the car will run permanently like that.
Also if you take it somewhere and have the computer plugged in, they wont be able to tell either unless it is doing it at the time.
What you need to do is pull over when it is doing this and disconnect the coil pack leads down the middle of the engine one by one.
When you disconnect a bad coil pack lead the 'miss' sound you hear will not change but if you disconnect a good coil pack lead then the sound will get rougher.
This is not a big problem just means the car is running on less than 6 cylinders because one or more of the coil packs may have a hairline crack in it and the spark is getting out and arching on the metal.
Once you have replaced/repaired the faulty coil pack/s it is a good idea to change the oil and oil filter as a lot of unburnt fuel is dumped into the oil.
I know that a factory replacement from Nissan costs around $250 NZ (too much), second hand ones are around $80 NZ (waste of time), aftermarket ones vary in price, I'm going to go for Splitfire coil packs from www.nengun.com which will be around $750 NZ for 6 and they also increse power slightly and are way stronger than factory ones.
If your a tight ass, then you can take out the problem coil pack and put some araldite over the crack if you can find it (I can't in mine) let that dry for a day or two then put some elctrical tape around it then put it back in. Very simple thing to do anyone can.
Have Fun and Your Welcome.
Yusssss! first post!
