    i felt like changing my spark plugs. i also felt like splurging on some pulstars. i now have a check engine light and something seems to have gone wrong. not sure what the issue is. anyone use pulstars before?

    I have read that setting the gap is critical for Pulstars and the Tundra ECU has had some issue knowing how much gas to send with these plugs installed causing the check engine light. I decided to stick with the iridiums.

    thanks friends, after my visit to oreilly, they said it was cylinder 3. and it wasnt the coil because we swapped them around reset light and rechecked after the light came back on. so im hoping its just a defect in the plug. if it still is im going back to the denso.

    how important is dielectric grease to be used?

    Dielectric grease... Called Dow 4 or light bulb grease.

    It is use to water proof power connections where water or moisture could cause problems.

    Any place where you have a power connection use it.. Also keeps rust from forming too..

    Just a FYI.. toyota engines are, a very pain in the butt with different spark plugs other than denso.

    so i have still been waiting on my new spark plug to come in. it is supposed to be coming in today. however...my check engine light is no longer on anymore. it used to flash...sometimes stay solid which is what normally was. also with LSD light on. i turned her on this morning no lights. ran fine. im going to take it to oreilly and see if there are any codes. i heard from a friend that since i didnt unhook my battery when i did it. it may have taken some mileage to realize there are different plugs....

    any thoughts?

    That certainly sounds reasonable. Maybe the reported issues I read about was mainly a lack of patience waiting for ECU to acclimate for lack of a better word. Hope the plugs work out for you. Pulstsar technology is kind of cool.

    Could be the computer relearning the new plugs. I do agree on the Denso though, they are all the truck needs. Don't forget to put some anti-sieze on the spark plug threads.

    The ecm was learning the new curve do to different spark plugs and burn rates why the cel was flashing. With the light off now the learning curve is complete. I wouldnt pull the spark plugs out unless the cel or engine gives you problems or fuel mpg goes down.

    ok guys. just got off the phone with pulstar. because im super paranoid. they are super nice and friendly. they are next daying me a whole new set. apparently is a misconception that their plugs are already gapped. i had no idea. i figured if they know the year make and model it is ready to go...apparently not the case. they come standard for the dg1h10 is 40. its supposed to be 44 for my tundra.

    so when you buy denso are they pre gapped for the truck?

    My Denso's were pre- gapped, but I check them anyways to be sure. Sound like Pulstar has good customer support.

    0.044 in or 1.1176mm. Your local auto parts will have the gap tool you will need for 5 to 10 bucks. Maybe less.

    remember to disconnect your battery so the ecm will lose the config on the spark plugs you have now. Touch the + and - together so the cap will drain totally out.

    That's good to hear. In theory you should see improvement with a more efficient burn. After a week or two you should really be able to see if mpg's go up.
