Newbie here. Is there any website that will show a breakdown of all the trouble codes for our Lightnings? :headscratch: I have an SCT Tuner but it only shows the code number, not what it is. Any help will be appreciated. ldtu: Thanks guys.

hey man i was getting this same code. well actually i got it two times. once because i got tired of draining my oil separator, so i put the return feed one inline with the catch one. it ended up cutting too much vacuum off. and once because i had the smallest vacuum line on the bottom of your rubber intake hose was off. its not always that line but i would say from all the forums i read on it when it was happening to me, i would say 90% of the time its just a vacuum leak.
