Compression loss in vehicle? (with video)
http://www.youtube.com/watch?v=NkV2PNuUr54
Notice it shifts at about 45 MPH and the engine seems like it powers down, at this point it has trouble picking up speed but it does pick it up, about 0:11 mark is when I left foot off of gas and then give it gas again at 0:14 mark, then let up on it again at 0:16 mark. Changed spark plugs but cannot figure out the problem. |

Good fuel pressure at the rail, sounds like it is going flat not a misfire?

Re: Compression loss in vehicle? (with video)
Well the ODB scanner has always reported Misfire on Cylinder 4. the Scanner has reported that for a long long time (2-3 years).
I never seen any misfiring in any of it though, this just started that within the last 2 weeks. I will also note and I dunno if it has any bearing on it, it wont do this with the AC running, but does it with the AC is off. This is the only time I tested that out though, I have earlier video from when the AC was on if I need to post it and was never doing this. |
