rwd_mayhem Posted February 21, 2006 Share Posted February 21, 2006 in my ae70 my 3a-u is playing up, you can hear sparking when listening to the motor, and it is causing the car to lurch when driving. what could be the possible causes? its electronic ignition so no points, it sounds as though it could be coming from the coil? ill look at it at night sometime and see if i can see the spark newhere. now when the car is on(not running) theres a noise from the coil as if its creating spark when it shouldnt, sort of a frying noise, is it something to do with electronic ignition?

Burntrubber Posted February 21, 2006 Share Posted February 21, 2006 Stuffed plug leads will cause spark to jump at the coil. Quote Link to comment Share on other sites More sharing options...
Gaz Posted February 21, 2006 Share Posted February 21, 2006 Stuffed leads. To see if leads are stuffed.. Pull lead off while car running and look down the lead. You will be able to see where the spark is jumping. If its jumping hard on a certain lead then insulation tape the end of the lead up real tight and plug it back on. This should temporarilly fix it. Also check the sparkplugs to see if any have small cracks etc in them. Might have dark black etc down one side of a plug indication a small crack. This can also cause spark to jump wrong.

rwd_mayhem Posted February 22, 2006 Author Share Posted February 22, 2006 but wen th lead isnt in the coil and the car is on(not running) it makes the frying noise, i have been told it could be the modular/igniter playing up. Quote Link to comment Share on other sites More sharing options...
