Ok well here goes, lately my car has been randomly missing. it would do it for a few minutes then stop. later sometimes during the same day do it again after starting the car after its been sitting for extended perioids of time. I ran the code and got a cyl 1 miss. swapped out coil 1 with 2 and vice versa. miss fire travled to cyl 2 as i hoped. so i aquired another coil pack and installed that today. now car misses at idle, and as soon as you give it some gas, it fires on all cylinders. and ive been getting codes p0300 and p0302. no cels for the miss at idle. after installed the coil in cyl 2, the first drive i took in it it would miss and come back then miss and then come back to all 4 at random. i think thats where my random miss code is coming from. then that problem leaned away to only missing at idle.
things about the car, the head gasket was just done a few months ago. the car is using jwt cams and the car is untuned using the stock throttle body.
the coolant pressure is known to be good
the fuel pressure is known to be good as well.
compression before repairing HG was decent for a car with 182k. no numbers outa the 14psi threshold.
the plugs are ngk iridium, one step colder, aixf6 or whatever the universal part number is.
ign timing seems to be on point.
up and down stream o2's are working
maf voltage seems normal.
i have access to snap on modis at work, but havent hooked up the lab scope to the car yet.
anything im forgetting or have any ideas to whats causing this?
