  1. Hi, I don't know much but... having had an intermittent hesitation for 18 months on my 1.6 4a-fe Carina E here are some comments. Determine the difference between a hesitation and 'running off one cylinder'. As my Oxygen sensor was the indicated fault code I was fooled into thinking this was some sort of emission/fuel mix thing, only to be told after fitting a denso equivalent sensor myself(from www.sparkplugs.com, and yes denso do supply the originals for Toyota) that it was always running off the no1 cylinder and that 'the oxygen sensor wouldn't cause that'. If you can deternime that the engine is running off one cylinder (remove each lead in turn when the problem is there), try swopping two plugs or leads over. My mechanic found that the fault followed the no1 BLUE FUEL INJECTOR to the adjacent cyl when swopped over. I got one from a breaker for £20 - he and this forum (elsewhere) say the blue ones give the trouble. Their plastic tops are blue where the grey elec connector attaches. I think determining whether the same cyl is always misfiring may save time and money. Maurice injectors were always prone to fail. they never put a code in or put the engine light on but the used to stay open and throw fuel in causing a misfire.

  3. My Carina E 1.6 illuminated the engine management dashlight in 2007. The Toyota dealer told me it was the oxygen sensor. I did nothing and the car has passed 2 MOT tests since. Maybe this is a fluke. Now the car has developed an intermittent hesitation, and if this is due to incorrect fuel management, it may not pass mot this time. Regards, Maurice
