Hello and welcome! My name is ***** ***** I can assist you with your question. Do you know what the engine vacuum is at when the engine i at idle?
Hello! You can check engine vacuum using a hand held vacuum gauge connected to any vacuum hose or line going to the intake manifold.
You should have approximately 20 inches of vacuum at Idle. I didn't tell you because you never asked.
Are you talking ignition or valve timing? I have having you check engine vacuum. Not checking for vacuum leaks.. although that should be done as well and confirmed that there are none.
Basically, anything that can cause the the camshaft and crankshaft to be out of sync will set this code. And yes, it can cause the engine to misfire resulting it misfire codes.
Hello! Sorry for the delay! I am aware of this TSB. This problem is causing the valve timing issue which is setting your code. The valve timing issue is what I was explaining. Does that make sense?
