Skurt

It's weird how it is exactly 30 seconds then it plays up and dies. Could any relays get hot and cut out? Not to mention it dies straight away when dead cold.

Sweet as, and yes I have replaced the fuel filter. Haven't replaced the ecu to eliminate that problem yet. Trying to find one.

I have resoldered the internals of the afm

Looking at the plug on the afm it looks fine and so does the wiring. Yeah I've replaced the CAS and nothing different.

Also tried another perfectly fine battery. It started fine but wouldn't idle like normal.

I pressurized the inlet system for any vacuum leaks and there aren't any, visually looked at all the lines also. While driving I have to double foot it so it won't die at lower speeds and stopping. (Just the same idling issue) I feel like something is drawing the current iswell because it won't start after a couple days of not starting. It slow cranks when that happens but then some times it's starts up ? it is charging, I checked with a multi meter. Maybe need to do another test of some sort?

Factory BOV. Also, the vehicle had a pod filter when I bought it so I put a factory air box back in with a new filter. Only aftermarket thing on the engine are the spitfire coilpacks. Bloody thing has me pulling my hair out.

Idling then dies IDLING ISSUES!! Hey guys, I have a 1994 r33 gts25t auto (rb25det). On cold start I have to use the throttle to get it going and use the throttle to warm it up. When it's warm 5 mins later I release the throttle for it to idle and it slowly dies. Start it back up with no throttle and she runs mint for 30 seconds then it dies again. Within that 30 seconds I can touch the throttle and it will idle until 30 seconds is up then again....it dies. Try to blip the throttle after that 30 seconds and it dies again. I have... Resoldered the afm and fitted another working afm. Replaced aac valve. Set tps to .45V. Fitted another relay for a constant 12V to the fuel pump. Opened up cold start valve and it was clean as. Vacuum tested the intake and no leaks occurred. Removed and cleaned throttle body right up. Checked ecu for codes, nothing appeared. Replaced temp sensor. BCPR6ES gapped to .8. Cleaned cam angle sensor. Checked ecu for any burn or corroded connections inside. Anyone please help me if they have had this issue, I've never heard of it happening.

Hey I have the same problem in my r33!! Did you sort it out at all? Cheers
