My car is having this weird problem, when I start the car in the moring (or cold) it runs like a dream. But if i drive it for a while, and then stop and leave it for a while (an hour or more), and start it again, it runs like shit. It won't idle, it keeps almost stalling then coming back to life. And when I drive it it will barly rev, and it bucks and carries on, the only way I can get it to go is to pump the throttle. It's hard to explain, but it's a pain in the arse.

The ECU is a remapped stocker (no 180k limiter, 8500rpm rev limiter, spark cut instead of fuel cut....) i'm thinking that the ECU dosn't like warm starts, but i'm realy not sure.

Thanks

hi sav.....ive had a verysimilar problem to this.....now im could be wrong... be but it could be a couple of things.....either u have some faulty coils and basiacally after uve been driving for a while it runs fine but then when u stop for a while the engine is still v.hot so the coils get heat soaked because the car isnt driving and having air pushed through the front....if that makes sense so try taping up ur coils for a start

or go get a leak down test done and see if u r having any leakage (sounds like it maybe)...i only say this cause i was having a similar problem and after checking it out further found that engine was not in great nic and it was time for a rebuild after similar symptoms 2 u...(not 2 scare u)

hope u dont need a rebuild too

good luck

The car is getting looked at on Tuesday, I have had problems with the AFM's in the past (a clean with carbie cleaner fixed that). If the AFM's need to be replaced will Nismo AFM's plug straight in without a remap. Just thinking for future mods.

    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
