INJECTORS not responding to ISTA
Hi All
Bit of a strange one. I have been having issues with idling on cold on scanning there was a misfire code for 1 and 3 which I cleared (stupidly) however I have had a look at turning the injectors on and off however. Only injector 2 makes the car run worse, so I know 1 and 3 have a problem. Now when I tried turning off 4,5, and 6 I get the attached error I think it is saying the ECU can't talk to it. Any ideas? |

the dme doesn't "talk" to injectors.
they are analog devices. and you need to determine if your issue is fueling or ignition. swap parts from suspected bad cylinders to other ones and see if the problem follows the part. I'm willing to bet the injectors are probably fine. check the wiring closely though, I replaced an injector for an intermittent connector issue. injector was fine. connector sucked. |

There are a few that have temperature limits. INPA usually indicates the required conditions. Not sure about Insta D, just never use it. It's too slow for me. INPA does what I like, fast and specific. |

What would the injectors not turning off when requested on insta lead me towards? |
