Hey, so I have a 1998 T100. It has a 2.7 l in it. It is a base base base model. Didn't even come with a side mirror on the passenger side or a reset button on the trip meter. As a matter of fact it's only got six digits for his odometer. Doesn't even have a trip meter. As I see on the motor I have e3r k83. I have replaced the plugs the wires and the bank 1 and 4 coil. I replace the coil because the number one plug was cold and I saw Sparks at night when I had the hood open. When I bought it, it had brand new injectors in it. That was approximately 2 years ago. They were about 6 months old and most of that time it had been parked. Due to this misfire thing still going on I think. As a side, the coil is available at Parts Plus for 33.99. It seems the misfire is not present when I start it cold. It only appears after it's warm. Not sure what's going on but I don't find any water in the oil or oil in the water and I'm not running hot so I don't have any gases in my coolant system.
