Adrian_L Posted December 16, 2018 Author Report Share Posted December 16, 2018 (edited) Using the injector cleaner after the engine light started flashing and all those error codes came up? No way.....#3 injector was done. I suspect the earlier engine shuddering was caused by the injector being on it's last legs. Maybe #1 too. In any case it made sense to replace all four as it only cost $160 in parts and the car is almost at 60K miles.

ptjones Posted December 17, 2018 Report Share Posted December 17, 2018 Just makes me wonder with 215k miles, probably 105k ICE miles my injectors are still running fine with injector cleaner every 20k miles. Paul Quote Link to comment Share on other sites More sharing options...
djc Posted December 18, 2018 Report Share Posted December 18, 2018 Problem fixed. The vibration seemed to get better for awhile, so we didn't bother with the injector cleaner. Then a few weeks ago, after a 30 minute drive on the highway the engine light started flashing and I experienced a rumble from under the front wheels. Fortunately it was only 5 minutes to home. OBDII indicated #3 cylinder misfiring and injector open. I decided to replace all four injectors as they're only $40 each (Motorcraft CM-5148) Fairly straightforward but I recommend you buy the special tool to disconnect the fuel line from the fuel rail. They're about $5-10. For future reference (unneeded, I hope!): What is the tool? A flare nut wrench? Can obdII distinguish a stuck or dirty injector from an open injector? Did you check with a meter to confirm the injector was open circuit? If the injector showed up in OBDII with a code for "open", I assume it means the coil is burnt out or there is a connector problem. I myself would check the injector with a meter for continuity before pulling it. If the injector coil was indeed open circuit, then injector cleaner is not going to help. ptjones 1 Quote Link to comment Share on other sites More sharing options...
Adrian_L Posted December 20, 2018 Author Report Share Posted December 20, 2018 This is a Canadian site, but they call it a fuel line disconnect tool: https://www.canadiantire.ca/en/pdp/fuel-line-disconnect-tool-0252017p.0252017.html?gclid=CjwKCAiAmO3gBRBBEiwA8d0Q4spnpdkW3mrhJELzf6LjZsQ3MfNMvS5CbAcA4T0gxR9f9AihjRcReRoCVEMQAvD_BwE&gclsrc=aw.ds#store=603 To be honest, I didn't have time to confirm the injector was dirty, stuck or simply bad. But it would make sense to check it out. djc 1 Quote Link to comment Share on other sites More sharing options...
