Hey guys hoping I can make this quick and easy and get my car running to it's full potential.
I've got a 1993 r32 manual, turbo, rb20, has basic starter mods as in intercooler and exhaust, coil packs.

When i turn the ignition and start her up she will start very well, idles around 900rpm. As soon as she hits running temperature she runs like a complete pig, idle goes from 900-300 and is constantly jumping from one to the other.
I took off the auxiliary air control valve, cleaned her out and still doing it.
Has aftermarket coil packs but not sure on brand (they're purple?) but haven't tested them yet, going to check my spark plugs this week also.
I put new silicon vacuum lines on and hopefully got them all. 
Air flow meter had a hole in the mesh but not sure if that'll make a difference, so i just bought a new one which i'm about to chuck on after i spray it with some contact spray.

Please help, driving me insane, just want to drive her again. :(

    • full send the cnut, do this   fark the wrapping and/or stick on siet. These guys are the ones to go to: https://www.realthermo.com.au/  
    • Just had a look, they don't. Fuelling on the base map is purely alpha-N, and the ignition table is MAP. Remember it's just a base map to get the car moving  
    • Hi everyone, I’m Dave from Canberra. Here's a few pics of my 1992 R32 GTST coupe which I imported back in 2006. Only mods so far are HKS Hi-power cat back exhaust, K&N filter, ATC Volanti steering wheel, Pioneer stereo, amp and sub. This was my daily driver up until 2015 and sadly hasn’t been driven at all in the last 5 years due to marriage, work, and kids taking up most of my time and spare cash.As such its in need of a bit of TLC and one of my goals for this year is to get it back to running condition and maybe look into club/historic rego. I’ve joined SAU so I can ask a few questions along the way (although I promise to google Current Problem +SAU beforehand!)
    • From talking to the mx5 guys the NC doesn't actually need bonnet vents like the earlier NA and NB models, due to a better designed cooling system and undertray design There's plenty of them used as street cars and weekend track toys running anywhere from around 170 to 250kw with stock non vented bonnets, I initially was going to get some bonnet vents, but, as they are not actually required, I'll put vents on hold for a while and just monitor temps, though I do need to get something to actually monitor engine oil temps though, coolant temp can be pulled from the OBD2, but the oil gauge in the car is not actual oil temp, it is only a calculation based off coolant temp and RPM ☹️ They do recommend upgrading the radiator, which I have already done with a triple pass, and the only other thing they recommend for a street car is heat management, like I talked about above to protect bits in the engine bay from radiant heat, and to either replace the nearly 20 year old plastic coolant expansion tank, which I have done, or get a aftermarket alloy jobbie for some bling They did also say that if I wanted to track the car on occasion a oil cooler and sump baffle would be required, and as I already have had a sump baffle installed when the engine was out......... I'm going to get a oil cooler with a thermostat....... just in case I do eventually track the car, but probably not, but still maybe...🤪
