Sign In I am troubleshooting a Mazda 6 2.0 -2007 which has one cylinder not running. I have confirmed that the spark plug is good and measured voltage for the spark plug wire whis also was ok. I then removed the fuel injectors to inspect them, and the injector for the non-working cylinder had this black plastic missing compared to the other 3. The pic is showing one of the other injectors, rubbers removed (one rubber above that black plastic, and one on the top). Pic: https://ibb.co/cJCvWSg All injectors seem to work when tested to back flush with a battery. Could it be that broken plastic is causing the issue? What is the purpose of that plastic?

Just move the injector to a different cylinder and see if the misfire follows it. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Sign In Also it wouldn't hurt to run a compression test to make sure there isn't a mechanical problem on that cyl.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
