2005 OR 150k miles
Last 30k miles on 35s 500-600lbs camping gear always
Oil changes routinely
First time I have actual engine codes beside the emissions ones but actually lost power under load.
Went on a out of state trip but on the way back my check engine light came on for the second time ( for these codes) but they stayed and have to semi limp home for about 150 miles. Not actual limp mode since I could do 65+ mph downhill and flat straights. Any hill or incline the engine would down shift and scream 3-5k rpm just to stay over 45mph. Very low but loud scream out of the Volant CAI , not common but sounds like a new exhuast system. Could be the misfire backfiring into intake.
So I realized the misfire could be a coil so I swapped with cylinder 2 same outcome. Went ahead and ordered cheap coils off Amazon for a test with new Platinum NGK plugs since the Iridiums (about 30k miles in) looked wore out ground side.
Put it together and it runs the same. Didnt compression test didnt have the proper extension.
Idles fine till the light turns on. The light is not on all the time but will flash underload( uphill/incline) didnt have the code reader during the actual trip but did check once I got home.
Timing Chain I believe is stock
Catalytic converter stock
These are just symptoms with a random issues I em currently stumped with. Out of 6+ years of ownership only time I couldn't figure it out.
Thanks guys
