Hi.
My car S70 2.5T LPT with RICA 235 remap has sddenly developed a very intermittent fault. Without any warning the idle speed suddenly drops to about 600rpm and then surges up and settles back down. It does this a couple of times and then it's ok. It starts up and drives fine otherwise.
Mine is the earlier version without the ETM.
Any advice welcome.
Thanks.
