Hi guys, having some trouble with the Z. Just wondering if any if the below rings a bell with anyone before I go down the "take it to the garage" route.
1 - I will post a video soon showing what I mean but here goes. Engine up to temp driving along, when i engage the clutch to slow down at lights for example, the revs will drop to 1500 or so, raise slightly to 1700ish before settling to around 1000. This happens over about 4-5 seconds. Once at 1000rpm it stays idling like that all day long. Is this a symptom of a failing/dirty sensor/hose etc? Resetting ECU does not solve this.
2 - there is a terrible flat spot in the power band between 3.8krpm and 4.3krpm. Everywhere else sweet as a nut.
3 - EML comes on after refueling, and intermittently for the next 100 or so miles. I believe this is something to do with fuel level in the tank, maybe triggering a sensor? With the EML on, the idle then stays at 1.6krpm until I reset the ECU.
4 - starting engine from cold, revs go to around 1krpm before quickly going lumpy, stuttering and stalling. Only way to stop it is to give it some gas for a few seconds and it steadies out.
Just wondering if anything here resonates with anyone, if my symptoms are indicative of certain components of systems etc, if there's anything I can do right now at home really. Thanks for looking and thanks for any help.
