P0301 - misfire cylinder 1
P0316 - misfire within first 1000 revs
5.4L Triton
I've got a few issues that I think are all rolled into one here and I'm trying to pin this down and see if I can resolve it myself before I take it to a shop.
First off, when I crank the engine after it's been sitting for a while there is a LOUD rattle noise for just a brief moment, maybe 1-2 seconds at most. It sounds like someone sticking something in a running fan but my radiator fan is clean and clear. It seems to only do it when the car has sat overnight.
Second, there is a constant tick. It's not coming from the engine compartment though, I hear it the loudest when I am listening just behind the front wheels. I was thinking maybe a leaky header connection or exhaust leak? It's been doing it for a while and I drive the vehicle off-road every other weekend so I figured I had just knocked an exhaust clamp loose and was hearing an exhaust leak. It's actually been doing it for like a year and I sometimes don't even hear it or notice it. I guess it could be something else?
The misfires happened yesterday morning and this morning. Yesterday when I cranked the car before heading to work it shuddered really hard and then got worse when I put it in gear. It settled down after just a short drive down the rd, just a block or 2.
This morning it did it again, only it didn't shudder as much when cranked but really started to when I put it in gear. This time the check engine light came on. It settled out after about a mile but the light stayed on. Just by luck someone at work has a OBD2 reader and that's where I got the codes from. After multiple cranks in the parking lot trying to get it to replicate, the light eventually went off and it's no longer misfiring?
It's been wet and rainy here the last few days and it's been really cool out with lots of dew/moisture hanging around the last 2 mornings. While messing with the car today I noticed a considerable amount of water leaking from a clamp on the exhaust pipe under the vehicle. It wasn't dripping down onto the pipe, i checked the top and it's dry, it was coming from the pipe itself I'm pretty sure. (this is not the same location I think I can hear an exhaust leak but about a foot or 2 behind it, directly under the driver seat area)
