Title: High idle after fitting decat
Post by: Bigmun123 on September 26, 2019, 10:23:06 pm

Hi folks,

Just fitted a decat to my Stage 1 MK5 and all went well, however it now idles at nearly 1,500 when it’s up to temp, which is a pain in traffic as well as just leaving the car running. The car has had a PCV Delete, it’s also got GFB DV and ram air induction kit with Scorpion Cat Back already fitted as well as being mapped.

Any ideas?!

Cheers

Check for air leaks/split hoses etc
