Dustinj Posted March 22, 2018 Author Share Posted March 22, 2018 (edited) And the reason I’m here. We just replaced the lift pump and fuel pressure relief valve. It was running great, and is now but has this funky idle that it wasn’t doing before. It’s up and down fairly quickly. Not a steady idle. The mechanic that did the work thinks there’s something in the injector pump causing the eradic idle. I’m trying to post a vid but it won’t let me if anyone would like me to text it to them to try to diagnose send me a pm and your number and I’ll send it to you I’ll post pics of the other rigs later today thanks Edited March 22, 2018 by Dustinj Quote Link to comment Share on other sites More sharing options...
