hi am shannon i will help on this issue
can you let me know which cylinder is missfiring?
and if that cylinder has a new spark plug and wire?
also the compression on any none firing cylinder?
please let me know the answer to those questions and i'll do my best to get you an answer
i se you are having problems with the chat
It was four but it is no longer misfiring, new plug and wire..haven't done a compression check.
i will switch to Q&A mode
then the next test you need to do is a vacuum test. hear is a video.
hear is a gauge for under $20.00
hear is a good chart
