So I have a JRE125 package which was installed about 3/21 and has been great. Car has been driven about 5k miles snice installation. I started getting P0300 which is multiple misfires. The CEL doesn't stay on and just blinks sometimes. Also sometimes I'm getting also P0331 which is Knock sensor but this comes on very rarely.

Just changed plugs and gapped to .032 how do my old plugs look?

Check Granatelli wires and there good.

is it leaded? I started having mis fire codes p300. I ran teckron fuel injector cleaner 1 bottle to half tank and it got way better. No more ck eng light but still misfires and did it again and its back to normal. I would guess the gray whites dusty look looks like lead to me.

Plugs should be ck at the end of a wo throttle pass. Chop the throttle and kill the motor to see whats really happening. Do it safely of course.


By the way seafoam made the misfires come back go figure

I guess I'm going to log a couple of WOT and see if someone can see something off on my tune.

Does the JRE package include a tune? And if so, how does the tune just randomly change?

I agree looks way lean but I'm not sure what the e60 does? It maybe that?
Contact JRE and show them, they may want some data logs?

E60 just gives more power and runs a little cooler. I will most like do some data logs and send it to Ted.

What's the gap on those old plugs now? Looks like 0.050 or 0.060 if I were guessing.

.040 which is what the NGK comes stock

They look very good other than you are getting some Oil on a couple plugs so a catch can would be a good addition to your car.

It is Definitely NOT lean, if it were the outer ring would be clean.

This is not a 2 stroke where the oil leaves a coco brown on the porcelain

The porcelain should be white down to the near base where you will see a fuel ring with a magnifying light at or about the Turn out to the steel housing.

The timing mark looks spot on as well.

I like a larger gap of 0.040 for best overall performance and Idle quality.

Misfire is only a problem when Wires start go go south.

I will be glad to discuss this with you and view some logs.

Thank you Ted

Good info to know

Thank you Ted, like always great customer service. I didn't get in touch with you snice I haven't had time to do some logs.

I do have a Catch can, weather is rainy in my area so hopefully next week I can do some logs just to make sure.
