R32 Gtr Problem

[widebody180]

1992 R32 GTR, been running great until about two weeks ago when I was driving home all of the sudden the car sounds like a tractor and it loses most of its power. When I put my foot down, the boost gauge would still show it making boost but it was really gutless and the loud tractor noise. After about 10 minutes more of driving it came good and started running all sweet again. Since that I've experienced the problem most times I've been driving it, on and off for about 50% of the time I'm driving it. Any ideas?

sounds like a coil pack. sometimes they can be fine when cold, then when they get hot they start to play up.

I have been having trouble with missfire higher in the rev range prior to this. Took it into a local workshop a few times to get them to check it out and they reckon they fixed it but kept happening. If it was coil pack getting affected by heat would it suddenly get better again?

Pull the coilpacks and look for arcing. They can be surprisingly intermittent. There's a DIY HERE

Definately the coilpacks. I had tried repairing them before but it never fixed them properly. Ended up getting some JJR coilpacks. The car runs so much better now, it's amazing. Doesn't misfire at all. Definately recommend new coilpacks instead of stuffing around trying to fix them.
