merckx Posted August 6, 2008 Share Posted August 6, 2008 (edited) I've just been out for a drive tonight and I only got a couple of miles from the house and buiding up speed on the motorway, the main warning light came on and the engine cut out. Numerous attempts to start it without success,it would start for a fraction of a second then cut out again. I left it for twenty minutes and managed to get running only for it to cut out again a mile down the road. I got a tow the rest of the way home. What's happened leading up to this: About a week ago I started to get a misfire when accelerating hard and approaching 1 bar boost, the main engine warning came on for a few seconds then went out, it was okay when taking it easy on the way home. So I fitted new spark plugs and new coil pack connectors . I went out for a drive yesterday to see what it was like, I had a little misfire under hard boost but it wasn't that noticeable. So I decided to drive back home again. On the motorway when cruising back and every time I accelerated a little it appeared to misfire really badly when in sixth gear. I've been checking all the connections on the coilpacks, sparkplugs and every other connection I could see on the engine before going out for a drive this evening and it cutting out altogether on the motorway. Any help would be appreciated, it's a right pain in the arse when you cannot check for fault codes on the vvti.

merckx Posted August 7, 2008 Author Share Posted August 7, 2008 Well, the fault diagnosis on the vvti engine appears to be working perfectly. Unsurprisingly I've got code 14. Ignition signal: No IGF signal to ECU for 4 to 7 consecutive IGT signals with engine speed less than 3000rpm. Link to comment Share on other sites More sharing options...

merckx Posted August 30, 2008 Author Share Posted August 30, 2008 What did you do mate? I removed both the crankshaft speed sensor and the single camshaft speed sensor (only one on the vvti), I gave them a little clean and amazingly the engine is performing perfectly now without any misfires at all.

Tricky-Ricky Posted August 30, 2008 Share Posted August 30, 2008 So do you think it was down to the sensors themselves being dirty, or maybe the connections a little corroded? Link to comment Share on other sites More sharing options...
merckx Posted August 30, 2008 Author Share Posted August 30, 2008 (edited) So do you think it was down to the sensors themselves being dirty, or maybe the connections a little corroded?They were just a little dirty and the connections appeared to be okay so I cannot be sure exactly. I didn't know what else to try and I was just about to order a new igniter, so I decided to take them off to have a look and measure their resistance across the terminals which was okay aswell. The misfire has definately gone. Edited August 30, 2008 by merckx (see edit history) Link to comment Share on other sites More sharing options...
