My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
My info is limited on your model here but I see no one else has responded and thought I would see if I can help here.
If you have not done a compression test at all this should be done.All cylinders should have the same close to compression.If cylinders 3 and 5 are found to have low compression this will cause this here and can be caused by a fault with the valves in the cylinder head needing replaced.
If this was already checked and found o.k. let me know.
Thanks Pete
