Hey guys (Newbie here)

I got this problem which is bugging the hell out of me.

Firstly I have a R33 series 2 96 model.

3 inch ext from cat back and a flitter. That’s all work that the cars has, other then that its stock.

The problem I am having is that when the car starts on cold is runs perfect until it is nice and warm.

The first problem is that the revs when put into natural either moving or stationary (Clutch in whatever) revs at about 1700 to 2000 rpm. Normally this is about 900 to 800 rpm.

This has just started to happen don’t know why? Please help.

The second problem is that when drive at low rpm like between 2 to 3000 doesn't matter what gear the car starts to jerk like it choking that is doesn't have enough petrol, I give more gas nothing happens however the vac goes up on the boost gauge. (Like a limiter has kicked in or something)

However if I down gear and put my foot flat the problem disappears until I start cruising again.

I have check for Val leaks and found nothing.

I don’t know I it’s my full pump but if it was it would this still happen when I gear down.

Fuel fitter has not been check.

If anyone has any suggestion it would be great.

Thanks

check for intake pipe leaks?

check o2 sensor?

and check your AFM?

also your AAC might need cleaning?

ive had similar problems after doing repairs on my car and forgot to plug in my AFM, or didnt tighten a silicon hose properly, resulting in the car reving and idling poorly..

      R34 Headlight lense replacement

      Behrman is great quality stuff. My 34 has some serious clouding as well but I’m too nervous to try and replace the glass myself so I haven’t bought them yet.

      How "plug and play" is the Haltech Pro for R33 GTST

      This might be true if you live in NZ but I can't see how this could be true for us locals here.  I've found the customer support for Haltech to be absolutely amazing. I've turned up to Haltech and spent entire days with their tech support guys, they've even helped me with wiring dramas that had nothing to do with their products.  They have the best customer support of any company I've dealt with, I can't imagine how my experiences with them could possibly be any better.

      If you want to do a single throttle body conversion easily, you won't need to pull anything apart. Take the linkage from your throttle off the linkage controlling the ITBs. Now open the ITBs wide open, and lock the linkages in said position. Now add a single throttle body onto the front of your inlet plenum. No it's not ideal for the last nth of a kw, but it'll be a lot better than what you're already trying to do...   PS, ITBs can be so damn hard to tune from, because roughly 20% movement in a throttle body equates to a change in roughly 80% of its flow (Hence power). When you add up the flow limitations of those small throttle bodys, it is a LOT higher than that of a single large throttle. Hence, TPS is very very sensitive with them, and you do a LOT of work with sensor fusion, and some Maths behind the scenes to make those blends nice, and be smooth.

      Yep, when Haltech purchased Adaptronic, and all of the Adaptronic staff, including Andy went with it, it took Haltech to the next level. Haltech wanted Adaptronic as they wanted things like Andy's fuel models, and some other IP, AND they wanted Andy too as he is brilliant! Andy has spoken about the incompatibilities between the old 1500 stuff vs Nexxus, and it totally makes sense. It's not JUST software that is different, there is huge changes in the underlying hardware too. It's why Haltech has had soooo many changes in the last couple of years, in terms of Hardware, and Software, and why it has become so damn Amazing. Why do you think guys like Rob Dahm with his quad rotor, went from running Adaptronic's to running Haltechs? Andy. Pretty much, Haltech these days, is Adaptronic, but with more funds behind it, and more staff, and hence Andy's visions, and visions of other people that he helps shape their great visions, into amazing new products. All the new Nexxus gear, whole new software for it, new and better dashboards, the apps that will run on headunits and NOT be slow to respond! I understand people being burnt in the past, but if you're ragging on a company, about products and issues from many years ago, it's more a reflection on yourself, not looking or keeping up with new stuff. In which case, those people should be going back to PowerFC and Nistunes as the ECU's to rave on about...
