Hemi. We did a complete cylinder head replacement. Have 120 psi on all cylinders. #3 still misfiring. Possible causes? kev2 Veteran Sep 16, 2016, 12:46 PM Post #2 of 3 (1690 views) Re: Cylinder misfire Sign In OK only 1 code - gotta ask you did use a SCANNER? A misfire cam be - ignition - spark - be sure they are firing, nice snapping blue spark... could try swapping #3 coil with #4 see if code remains #3 or moves to #4. Fuel - injector issue - clogged, no pulsing, or leaking inj. - How does #3 plug look, black, wet, dry, tan.Fuel fuel pressure leak down KOEO. next suspects - BUT confirm the above- they are more likely Mechanical - compression or vacuum - you have comp - use oold spray trick for a vacuum leak.i (This post was edited by kev2 on Sep 16, 2016, 12:53 PM) Tom Greenleaf Ultimate Carjunky / Moderator Sep 16, 2016, 8:28 PM Post #3 of 3 (1673 views) Re: Cylinder misfire Sign In Quote">>Have 120 psi on all cylinders.<<" Caught up with just that borderline for an engine to run at all. Are you sure that's accurate for compression? Full test done properly or how did you get that #? How much did it come up with a wet test on each? This alone doesn't add up. I don't think I've ever seen all cylinders read the exact same compression and IMO that's too low if correct and still whatever is causing one cylinder not to fire to find and fix   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
