Boneybradley 2 Posted February 13, 2014 Report Share Posted February 13, 2014 I am having really bad miss fires (and low low power/stalling) on my obd2 2.8 and before spending money on various parts I was wondering if anyone can point me in the right direction. When first started cold it drives fine until it gets some temperature when it misses and it's also fine for a minute or two when started when warm and then again misses, I have looked for arching on the coil pack but didn't see anything (I also checked leads and no arching was spotted) I have scanned it on vcds and it shows a lambda fault code (then again it's had this since I bought it and I put this down to the fact it has a de-cat and milltek and was running fine before with the code), I also checked the temp on vcds and it goes up to and stays at 75degrees (even when fully warm), Are there any other measure blocks to check that may pin point the issue further?(I know the 4cyl engine blocks ok but not the VR) I was thinking of changing the ecu temp sensor and seeing if that helps but before spending money I thought I would ask the experts any help welcomed Link to post Share on other sites
mattvr6 133 Posted February 13, 2014 Report Share Posted February 13, 2014 Sounds like ur coil pack is breaking down when getting hot have look c if it got any cracks around it also when it's running at temp spray a mist of water over the coil pack c if there's any arching Sent from my iPhone using Tapatalk Link to post Share on other sites
Boneybradley 2 Posted February 13, 2014 Author Report Share Posted February 13, 2014 Well I am going to try a coil pack and also do the temp sensor due to the erratic readings, (It's a shame vcds can't narrow it down for me!) Link to post Share on other sites

Boneybradley 2 Posted February 15, 2014 Author Report Share Posted February 15, 2014 well temp sensor ordered (will be with me to fit Monday) here's hoping for an easy fix and I can get driving it again (I miss the noise! Driving the 8v Anni is not the same) Link to post Share on other sites
Boneybradley 2 Posted February 17, 2014 Author Report Share Posted February 17, 2014 ok temp sensor has not worked.... time to find a coil (to test as I will fit a new one if that solves the problem) Link to post Share on other sites
