Danriv957 Posted October 16, 2021 Report Share Posted October 16, 2021 I'm trying to get my engine to start up but I am having trouble. Right now I get an error saying the fuel mixture is too lean and am getting a reading for -101 MGP and lambda at 0.000 I haven't connected any vacuum lines yet. Can that be the cause of my problem?

Adamw Posted October 16, 2021 Report Share Posted October 16, 2021 MGP should be near zero with engine off, -101 means there is a set up issue. There will be no fuel injected with MGP showing a total vacumm. Attach your tune and I will take a look . Quote Link to comment Share on other sites More sharing options...
