So there are other threads out there with idle issue problems but they all seem to lead to IAC valve or vaccum leak. I have cleaned the IAC/AAC and a guy who did some repairs (Forge Performance, SA) said that if there was a vaccum leak, the idle issue would be constant. Basically the idle bounces up and down and is no longer dependent on the Air-con/Lights/Radio, but they have an effect as to how low it falls. My coil packs are breaking down under load and need to be changed. Could they cause an idle issue? If not, what could? (Apart from vaccum leak and IAC/AAC) Thanks

Hey guys. So I bought a 1994 R32 GT-R. Car drove amazing when I first got it. It only has 84,500 km's on it. The weekend of the week I picked it up. I decided to do a service which entailed: . Oil . Oil filter . Air filter . Rocker cover seals and half moons . New front brakes . Fuel filter . Iridium spark plugs The car already came with splitfire coil packs. After driving for a couple of days, I noticed my car started to have a bit of a stutter. Wasn't bad. Few weeks later I went for a drive was stuck in traffic for a bit then when I started to drive it started to misfire severely. It started to sound like a wrx. It was a warm day but it never used to do that. Took it to an auto electrician tested everything possible that could cause a misfire and everything was getting power. Did a comp test all cylinders had the same reading. Changed coil packs and spark plugs and it still does it. When it's first started and driven it's fine. As soon as I drive for 30 mins it starts to miss. Even if I have short drives, turn it off start it again it struggles at idle thwn revs pick back up. I lose alot of power and is super sluggish! Any ideas on what it could be?

Relearn idle issue when set ok the idle increases jumps to 1000 then 1500 rpm or more clear fault code And settles the ramps up again, replace cam sensor made no difference could it be nackerd ecu not holding its Perimeters

I got a rb25de r34 neo n/a, when I start the car it idles on 2000rpm, after about 5 minutes I can turn the car off and start it up again and it will idle like normal, when it's 2000 rpm, disconnecting the tps will lower it to normal aswell, what could cause this?
