JustBlaze Posted October 7, 2022 Report Share Posted October 7, 2022 Hoping i can find some help here, as heading says, i'm experiencing hesitation / jerking under low and high rpm. i must admit i am a newbie when it comes to analysing Logs, so im hoping someone here will be able to point me in the right direction as i am all out of ideas. so far i have done Boost leak test, re gapped plugs to 0.20, checked fuel system (pressure is good) resistance on COP system is good evo 1 4G63T if anyone is able to take a look at this small log and shoot me any advice what i should be focusing on would be much appreciated.

Adamw Posted October 8, 2022 Report Share Posted October 8, 2022 You've got accel fuel dumping in all the time. It could just be set too sensitive or not enough deadband but your TPS looks more erratic that I would normally see so I suspect there is something wrong there.

JustBlaze Posted October 8, 2022 Author Report Share Posted October 8, 2022 Thanks Adam! that helps a lot, it is a new TPS which is probably why i didnt suspect that, could be a grounding issue. will look in to it. thanks again Quote Link to comment Share on other sites More sharing options...
