ADD Posted December 16, 2008 Share Posted December 16, 2008 Howdy all, my supra has been out of the garage for about 12 days now so has experienced all that frosty weather. So today i thought i'd give it a drive, but the battery was flat. so charged her up (took an hour) and went on my way...UNTIL the engine management light comes up and the car turns into a machine gun (well certainly sounded like it) it cleared after about 2 mins then came back on again, then cleared the came back on (an so on for 5 miles)! the car wouldnt accelerate at all it was just hesitating. my question is could it be the frost has got into the coil packs and making it misfire? or would it be something to do with the battery going flat? any help would be great.

bignum Posted December 16, 2008 Share Posted December 16, 2008 If you`ve got antifreeze in your cooling system the frost won`t be your problem, more likely to do with having a flat battery and your ecu relearning, you shouldn`t be getting the red triangle on though unless there is another problem, you need to check for fault codes.

ADD Posted December 16, 2008 Author Share Posted December 16, 2008 cheers for reply mate, its not the triangle that flashes up its the one on the righthand side display that looks like the side view of an old plane. but i shall definately check error codes tomorrow Quote Link to comment Share on other sites More sharing options...
ADD Posted December 17, 2008 Author Share Posted December 17, 2008 I have error code 14 'No IGF signal to ecu' has anyone any idea where to go from here? cheers Add Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 17, 2008 Share Posted December 17, 2008 Try removing the connectors from the ignition amplifier (igniter box) and refitting them, if that doesn't fix it fit a new amplifier.

ADD Posted December 17, 2008 Author Share Posted December 17, 2008 would it be worth me checking coils packs/plugs etc as well? great stuff thank you chris!! were about is the igniter pack located matey? thanks Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 17, 2008 Share Posted December 17, 2008 I had assumed you would have already checked / changed the coil pack plastic terminal clips. They are now a basic service item on the MKIV. If they are loose, suspect, or broken, change the lot. If you are lucky it may fix it A search should come up with the part number, I think Paul Whiffin stocks them, or any Toyota dealer will get them.

They were changed about 5 months ago due to a miss fire but now with the car being left out in the frosty weather they may have got some damp in them.

Chris Wilson Posted December 17, 2008 Share Posted December 17, 2008 I am sure Toyota doesn't expect a bit of mild frost to disable the ignition system to the point of misfires, or a large number of people worldwide would be not getting to work I'd doubt a bit of damp on a LT circuit connection to the coils will cause any trouble.

ADD Posted December 17, 2008 Author Share Posted December 17, 2008 very good point! i'l check the igniter pack tom! where is it located chris? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 17, 2008 Share Posted December 17, 2008 Inner wing top, passenger side, black square box. I would think a search will find a photo here somewhere. Quote Link to comment Share on other sites More sharing options...

ADD Posted December 21, 2008 Author Share Posted December 21, 2008 Right renewed the batt as it was duff, pulled off connectors and refitted it seemed to clear the prob for about 5 mins then came back on. The car seems like it only running on 3 or 4 cylinders or something, it shakes badely when on tickover and absolutey stinks of fuel! next step to replace ignition amp you say? would this really make the car miss so badely? cheers Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted December 21, 2008 Share Posted December 21, 2008 Sorry for the hijack, but thats an excellent link Chris Quote Link to comment Share on other sites More sharing options...
gaz1 Posted December 21, 2008 Share Posted December 21, 2008 might be worth resetting the ecu, pull the 2 fuses or disconect the battery for a minute or 2 and then try Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted December 21, 2008 Share Posted December 21, 2008 When were your plugs last changed? I presume this starts to happen when you start giving the car more revs after you have let it warm up right?? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 21, 2008 Share Posted December 21, 2008 If it were here the first thing *I* would do is fit a brand new set of platinum electrode plugs and go from there, even knowing the plugs in it are very new. Quote Link to comment Share on other sites More sharing options...
ADD Posted December 21, 2008 Author Share Posted December 21, 2008 plugs/coils packs and clips were changed 2k miles ago. This has only happened since the battery went flat and it was left out in the frost Chris i'l go for that mate cheers Mikey the cars starts up like it and then can clear for 2 mins then comes back again. very very annoying!

stevie_b Posted December 22, 2008 Share Posted December 22, 2008 ADD: small hijack for my own info, but what did you use to charge the battery within an hour? Was it a jump from another car, or one of those mains-powered battery boosters? (I ask because I may be in the same position myself with a flat battery, but thought that the boosters needed 12 hours ish to do anything) Quote Link to comment Share on other sites More sharing options...
