Thomas haefner: You are smart at this stuff. 1 question, Why does it need to be clean, that is my only question.
Nicholas Rowland: Hi all,
Wondering if anyone found a fix. I've been getting the cyl 5 misfire for a couple years now. Only during hot highway driving. Changed plugs and wires a few times with factory equipment which seemed to help for a while but problem always comes back. Has anyone checked the injector? Thanks for the great video!
othour eddaki: hi Robert, i wonder what is the voltage at connector harness to ignition coils when key ON engine OFF. i found in my 3.7 V is it normal or must be 12V. thanks
Mattias Nord: Hi Robert, I got the engine check indicator a couple of days ago when reving the car out onto the freeway, then it turned off, but I got curious so pulled the fault codes and there it was "misfire cylinder 5"! So I found your video and just wanted to ask if you did replace the fuel pump and that solved your issue? I've had my car in at the used dealers shop twice before, last time it was a lose fuel intake sensor so air was leaking in during a couple of months. Imagine the mileage of the engine during that time.. :P
TheBenno007: hey Robert, nice video! i too have a Hyundai Tuscon v6 2006 although my problem seems to be misfire on cyl 1 and 6 clear codes and same codes come back also a lean code (p0174), i had no issues with the vehicle until i had the timing belt changed, the mechanic also change high tension leads and plugs, after he replaced cooil pack but still have same problem will check the depth the h/t leads fit into coil pack fingers crossed.
Robert Thomas: Hey guys I thought I would let you know that I went to Denver Colorado in 2012 and 2013 and each time I had the same problem. I get a miss fire code on cylinders 1, 3 & 5. Which are under the intake manifold. I really think that driving from Tulsa OK to Lemon CO (roughly 8 hours) cause a vapor lock in the fuel rail on the back side of the engine. I now believe that was my problem in this video. We are returning home from a long road trip. Perhaps I should replace the fuel pump, it make be weak.
Robert Thomas: No problems with check engine light or misfire as of April 2013
Mike Moretti: very detailed and informative - thanks for taking the time to do it.
V Souza: Has other software more user friendly?
