[quote=”allhan” post=150827]Hello 🙂

Have you check fuel presure?[/quote]

I haven’t checked fuel pressure because I would have to buy a special tool just to connect up to the fuel rail. This car doesnt have any shrader valves or any ports to test pressure.

Sorry about that. 2006 Dodge Charger 3.5L V6.

Here’s a complete list of what I’ve done so far since first getting the misfire code:

– New Gas Cap
– Change spark plugs & PCV Valve
– Change ignition coils
– change fuel injecter on cylinder 1
– clean throttle body
– Seafoam via vacuum line
– Clean short and long run actuator (Cleaned with carb cleaner)
– cylinder compression test (looks good)
– swapped spark plugs 1 & 2
– Clean IAT and MAP sensors
– New cam and crank positions sensors
– Vacuum test (looked good also)
– New plenum gasket
– New EGR valve & gaskets
– New Evap purge solenoid
– New o2 sensors (upstream)
– Removed and checked the vapor/charcoal canister and the hoses look good and the
canister itself did not have any cracks either. I took a hand vacuum pump and
pumped a bunch of air in there to see if maybe it’s clogged and could possibly
loosen it up a little.

So, I have probably done way more than I should have but since I have 112,000 miles I figured I might as well change some of this stuff just for preventative maintenance anyway.

When I first start the car the STFT percentages are in the negatives and the idle feels good. Then they gradually work there way up to the positives and that’s when the idle gets rough again.
