hodge Posted May 9, 2006 Share Posted May 9, 2006 Ive managed to get it running again but still stinks of petrol on tickover. if its left ticking over for a while and rev it to about 3000rpm it blasts black carbon stuff and what looks like either neet fuel or water from exhaust. its not lumpy on tickover anymore since ive changed the coilpack clips but I took it out for a run and it wouldnt boost past 0.5 bar. If my foot was just on the throttle it was drivable but if I put it down any it would start to splutter and hold back. It wouldnt return to normal until I took my foot off the throttle. it feels like there its under fueling but I think its over fueling on tickover. I cant find any pipes off or splits at all. Ive done a code fault check and the only thing that comes up it a flashing O/D light, the warning light comes on and just stays on untill I start the car then it goes off. Ive done some searches and the O/D light means the delimiter or speed sensor is shagged. Can this cause the over and under fueling problem. PLEASE HELP. I need it back on the road ASAP.

Guest pektl Posted May 10, 2006 Share Posted May 10, 2006 hi mate! check your spark plugs...there could be engine flooding and your piston rings are worn out...my previous ride had the same problem and only manage to find out that the pistons rings are worn out and the engine was flooded as i was running some big injectors...good luck!

Ian C Posted May 10, 2006 Share Posted May 10, 2006 Still sounds like you are overfuelling If your AFRs get to 9:1s and lower you'll misfire and lose power as the mix just plain won't burn. -Ian Quote Link to comment Share on other sites More sharing options...

ManwithSupra Posted May 10, 2006 Share Posted May 10, 2006 Check your vacume hoses to. This can cause similar problems. Quote Link to comment Share on other sites More sharing options...
hodge Posted May 10, 2006 Author Share Posted May 10, 2006 The car has sorted itself out dont know how or why it just has. Everything seemed to be pointing towards the map sensor. My E01s pressure sensor is cennected into this so I altered the display to show boost the car was fine. It was cold when I started it and it ticked over fine, so I thought id try my luck down the road. It was back to its normal self boosting to 1 bar again no problem. The thing is I dont like thinks that fix themselves I like to know why it happened. But I suppose never look a gift horse in the mouth and stuff.
