    It's constant, unfortunately.

    BUCKLE UP! It makes it harder for Aliens to pull you out of your Truck.
    Stop. Wait a minute. Pop #1 coil out and if the tip of the coil is wet with oil, you need a new valve cover and (more importantly) spark plug tube gaskets. They’re like $30 at Anal Zone. Good luck

    Thank you, I really need luck now. No oil on plug, just had alternator tested, it seems to be ok. New battery so it's not that. Will hopefully do compression test tomorrow or Sunday. Battery light came on, threw a c1241 code so maybe alternator isn't good, lights seem to dim sometimes even with new battery. Would be tearing out my hair if I had any.
    Anal zone, good one lol

    Swapping out alternator tomorrow and doing compression test, hope that tells me something. Alternator tested ok but under load with lights on headlights would dim and battery light would come on when I turned (wtf?) Wish me luck that I either fix this tomorrow or at least find out what is going on.

    Thank you so much to everyone!!! My taco is fixed and back to running like a champ. Turns out everyone was right lol. My alternator was bad, battery died and 2 of 4 coils I got on eBay motors were bad out of the box. Replacing alternator did not fix misfire so we started swapping coils around and the misfire began moving around. Replaced 2 coils and everything went great. We then did a pressure clean on injectors (look for "fuel injector cleaning in less than 5 minutes" on YouTube) and it's running great again. Thank you so much to everyone, we had plenty of things to check lol but it turned well. Will never buy parts from eBay again.

    You too. Had another coil fail on me but swapped it out for a napa coil and it's running well again. Will never get parts on eBay again.

    I had just reconnected the battery like 5 minutes before having it scanned. It turned out that 3 of 4 coils I got on eBay were defective and that was the whole problem after replacing alternator, battery.

    Sounds like my story but I had original coils. It was weak coils all along. Edit: my God this truck pulls better than new. I guess I should have replaced them 8 years ago
