have you inspected the spark plugs yet ? also look for signs of rodent damage. they like to chew wires and nest under engine covers where it's warm
are you able to unplug the affected cylinder and will it make a difference ?
plugs looked ok, smelt like gas, the threads a little moist but not the end of the plug it self, computer says misfire is 1 and 4, but all 4 plugs look the same. i thought the inj cleaner w/ cyld lube caused this
ok switch the coils around put the #1 into # XXXXX and see if it changes cylinders. you could have a coil that failed but i have not see 2 coils fail at once. at least we can isolate the problem
resistance plays a big part. thats why swapping the coils around we can see if it affects a different cylinder.
its a very easy step to take and it will lead us into the correct direction.
thats why i was suggesting while it's running unplug the coil and see if if changes. if it does then the coil is firing and we can move to the next step.their is a process we need to follow.
you wont need the scan tool for these simple test.
ok, i will let it run until it mises this will take a few min, i will get back to you as soon as i know something
very well i will be here
we see a lot of pin fit problems and yes some time just unpluging and plugging back in makes a new contact on the pin fit.
please dont forget to leave feed back after the accept.
