Hi, welcome to Just Answer. I’m Ron and I’ll be helping you
today.
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

You can also have a compression problem or an injector that is bad or not getting power. You would need a compression gauge and a NOID light to test these.

Thanks, Ron

I was wondering if injector would cause that code.
Expert:  rpmdiag replied 3 months ago.

yep, sure would, it's still a misfire.

Thanks again and please remember to rate me 5 stars and keep this link in case you need me again later on.

What exactly causes p 0357
Customer: replied 3 months ago.
It is pending everytime start engine
Expert:  rpmdiag replied 3 months ago.

Most likely a fault in the ignition module/computer, not getting a signal at the correct time.

Cam sensor?
Expert:  rpmdiag replied 3 months ago.

Has nothing to do with it. CRANK sensor can though. Attach your lab scope and make sure these signals are coordinated.

Customer: replied 3 months ago.
Don t have a scope
Expert:  rpmdiag replied 3 months ago.

You need one

Customer: replied 3 months ago.
I ll order a crank sensor. Only 25 dollars. And try that. Any other suggestions
Expert:  rpmdiag replied 3 months ago.

Nope, no guesses that I can think of.

Please remember to rate me for my time, knowledge and valuable suggestions.

Thanks again, Ron
