I just took my r33 gtst out for a spin (the temperature here is about 40 degrees C) and it was running really rough, backfiring lots and stalling quite often. Could rev it while idling in neutral and the thing would just stall when u back off. The engine was surging a bit as well. It was running fine when I was driving it the night before.

Does anybody elses car run rough on hot days?

i have an r32 in the heat it sometimes idle's a little wild like jumps up to 2,000rpm and drops or idles high, but i usally let it sit for a while and it sorts it self out,

maybe in your case the your tunes not up to the hot weather?

do you have standard ecuor aftermarket??

i have a series 2 r33 and i was almost beaten by a vn commodore the other day when it was about 32degrees. i was disgusted. however im 95% sure this is because i have a pod filter on my car and it sucks in alot of hot air from the engine. im looking at getting some piping and mounting it to the front bar soon. but overall yes my car does run worse in the heat. i love driving on a nice cool night. so does the car!

I have the same problem. Yesterday and today the temps have been 38 and 41 and since yesterday when I went to start my car, that had been sitting out in the sun for about 4-5hrs, the car would idle at 700-800rpm but then drop down very low (100rpm) and then try to raise up again to 700rpm. Sometimes it would not raise the revs and just stall. If I start the car up and give it a little gas to raise the revs up to 1500-2000rpm for a bit the car settles down and drives normally. Has the heat damaged something in my car?

Thanks for the response MintR33. The idle problem only seems to happen when I start the car up after driving it for a while so the engine is still warm (or hot as the case has been the last couple of days with the weather in Adelaide!), I don't have the a/c on at this stage. Once the car has been driven for a short while the car idles normally at the lights even with the a/c on. I have just had the cooling system and a/c system fixed with all new parts, but the car was fine after all that work. It has only started with the extremely hot weather.

mine does the same, hell a barina sri kept up with my r33 gtst on a 40degree day.....i was like wtf?

i believe that if you have a pod filter shield it off, do whatever you can to get colder air in and should be a bit better. but yeah turbos sucking in hot air does't exactly make performance increase..

It's not like I'm asking my car to do anything special. I'm not even wanting the car to perform well in 40 degrees just wanting it to idle normally and not stall.

I take it that others whose car has had idle issues in hot weather haven't been able to fix this problem?

Its not about performance in hot weather but as to why his car is basically not drivable in hot weather.

yeh, my car is a piece of shit in the hot weather...much slower
mine just feels like it has a little less power, apart from that the idle and everything else is fine in hot weather

...... do i need to point anything out further?

the post where i stated " its common sense turbo cars wont perform in hot weather " was directed towards them posts. and clearly... them posts are stating they are giving there car shit in hot weather and the cars not performing like they are used to in colder weather. i hope to god i dont have to explain WHY this is so...

Well im sure you could add something more constructive towards the issue that "understated" is having other then "yeah lets all go flog our turbo cars in 30-40 degree weather. realllll smart"

He isnt talking about flogging his car in the heat even if that seems to be where rochey took this thread in his battle against a vn commodore.
