starletboy Posted May 6, 2006 Share Posted May 6, 2006 yep mine did same thing just took my convertor off and all good its just somethin they do when either speedo is disconnected or a dodgy convertor!!!! Quote Link to post Share on other sites
ecksjay Posted May 6, 2006 Share Posted May 6, 2006 the begininnings if fuel cut? mine comes on just before i hit fuel cut, but obviuosly means it was VERY close, so it may well have been that. Quote Link to post Share on other sites
*Toymota* Posted May 6, 2006 Author Share Posted May 6, 2006 Strange thing is when trying to do the ECU test for the codes when I put the paperclip in the EM light doesnt come on. I have checked the clip was in the right place.Does the light have to be on before you put the paper clip in?Also when the EM light is on the car idles around 1000rpm instead of 750rpm.Any ideas Em Quote Link to post Share on other sites
klyfax Posted May 7, 2006 Share Posted May 7, 2006 It becase the ECU goes to satety run, then the light are on... Quote Link to post Share on other sites
ben_j Posted May 7, 2006 Share Posted May 7, 2006 if it goes off when you turn the engine off and back on again. then comes back on when you put ya foot down hard. its the fuel cut isnt it? the engine is saying its underfueling. mine comes on when i boot it, but it doesnt matter as my piggyback ecu overrides and still fuels correctly Quote Link to post Share on other sites
*Toymota* Posted May 7, 2006 Author Share Posted May 7, 2006 im only runnin an exhuast an induction kit. boostin at between 0.7 - 0.8 barr. that not near fuel cut is it? plus it feels nippy an idles slightly higher occasionally when stopped? Quote Link to post Share on other sites
