New Spark Plugs, Engine Light Appear
I got new spark plugs from Toyota for my -00 Yaris from Japan.
They are Denso K16R-U as it should be, I gapped them to the old ones (NGK BKR5EYA) which was about 1.8. But later I read they ought to be 0.7 for my engine, took them out and gapped them to 0.7. It felt like the engine had lost power and it was hesitant on 1st and 2nd gear. After about 75 km the engine light came on. I read that you are not suppose to gap the original spark plugs and Iridium is sensitive so I thought that I had broken them. Bought a new set, no gapping this time and it again felt like the engine had lost power at some moments. Sure enough after about 75 km the engine light came on again! Why I wonder, I did it right this time with original spark plugs but it seems like it wants the old NGK back with the 1.8 wide gap. The only thing I can think of is if they at some point replaced the engine to the french one which should be gapped to 1.1. I will check my engine ID and get back. Does anyone have any idea what might be going on? |
