... in sync in my Head is, why is there a second pressure after the Compression when snapping it, while at idle the Pattern looks fine ?? And if the WPS is not lieing, it is over 1,5 BAR !!! I thought maybe Exhaust pressure, but connection to the front O2, we can not get the Gauge to get over 1,5 ...
As I said in the original post, I first checked with the wps, then rechecked with the gauge, both agree with each other. The car starts and runs fine, other than the intermittent misfire. The compression is, I suspect, being held low by the inlet valves. ...
Hi guys, need a little help with this one... Fiat 500 twin air 2011, 30 seconds after cold start has what feels like a single cylinder ... and ignition primary, all ok. Decided to check running compression with wps, low, really really low, to the point I thought I’d got something wrong. So ...
... during the exhaust stroke. This is supportive to the accuracy of the WPS500. This brings up another point that the high cylinder pressure of cylinder two is caused ...
... an engine, a previous capture, VM tech Info, Pico Library..... .... The WPS or Equivalent (PV350) is the way forward and that still will not be as ... tool, for engines not born with them, which does not have the 500 psi or temperature limitation. Watch this space :D
