Interesting. I had a look but could not see any lights. Good news! I put a set of Splitfire coil packs in and some new NGK BCPR7ES-11 spark plugs and now It pulls harder than its ever done. 😊 Thanks everyone for your suggestions! Just wanted to make sure that was it before spending decent money. Hopefully there aren't any more dramas.

Thanks for your suggestion too! I've got a set on order so fingers crossed.

I would have thought the #1 most common problem would be between the seat and steering wheel. Forgot to mention I did replace the fuel pump a while ago and it was the same before and after.

Right I didn't know that could be a thing. Thanks for letting me know! Let's say it is the coils. Would you recommend getting this kit? https://www.platinumracingproducts.com/products/rb-r35-vr38-coil-bracket-kit-rb20-rb25-rb26?variant=37826663973032 Will these run ok on the stock ECU for now? I'm chasing more power and have a Link ECU ready to go in but it will be at a later date.

I remember changing the spark plugs a while back and it still had the issue. I will try unplugging the coil packs when I get a chance. I feel like my problem is more subtle than a complete misfiring but I guess it doesn't hurt to try. It still has original coils. Is it possible somehow they could be failing but not totally failed yet? Thanks for your help Duncan! I'll report back after I test.

Hello SAU! I need some help with a problem I've been having with my R34 GTT. Under heavy acceleration and load the car does not pull hard at all. It stutters, hesitates and struggles to pull through the revs. Its sounds similar to it hitting the limiter. Sometimes it's very serious it can be felt just above idle like in the video. You can hear a low popping sound @40s. (use good headphones or speaker with bass). Sometimes the problem goes away entirely for a bit randomly so its super annoying to track down. But now it happens more often than not. Engine mods: Custom 3" exhaust, Apexi pod filter, new O2 sensor. Already tried injector flush and cleaning MAF. Any ideas and suggestions will be greatly appreciated. Thanks! PXL_20210904_082139833.mp4
