Hello Scotty,

I have a 2008 Dodge Nitro R/T, 4 liter V6 Automatic, with 138000 miles. Bought it from new at Daimler/chryskler here in France, (I'm danish living in France haha). I'm a conservative driver, no burnouts. Use as daily driver. Bought it to replace my old Jeep Cherokee limited 4.0 Litre, as I love square cars. I baby it, change oil/filter every 6 month, do most of service myself, had the timing belt, water pump, pulleys replaced last year at dealer(2400USD), transmission fluid checked and replaced 3 years ago. 

When I drive around 30 to 40 miles an hour and accelerate, car hesitates, sometime won't accelerate right away. Oct 27 21 , I accelerated to pass a car, it kicked down with high rpm, engine light came on and flashed , I stopped shortly after, used my blue driver and got code P0201(Fuel injector 1 circuit open) and P0301(cylinder 1 misfire Detected).

I have occasionally felt some misfiring at idle, but not much, thought it was just due to age. I  have since then replaced, Battery, 6 fuel injectors, 6 coils, 6 spark plugs, 2 oxygen sensors, MAF, MAP, PVC valve. The crankshaft and camshaft sensors was replaced Nov 2020 as I had some misfire shown in Mode 6.  I did a carbon cleaning 2 weeks ago, which made the car run a little better. Also did the throttle body cleaning as you advice on video. Air filter is clean. It doesn't seem to burn oil. 

I still have misfires, now with pending codes P0172(system to rich bank 1) P0175fuel system 2/1 rich) P02096 post catalyst fuel trim too lean bank 1)  P02098(post catalyst fuel trim too lean bank 1). Misfire is mostly on cylinder 3 with between 25 to 60 misfire in 1 hour drive. Car only starts in second attempt. I idle for 2 to 3 min before putting it in drive, as it drives better when warm. At full operating temperature it runs fine, hardly feel any misfire. but when I'm at a stop and  accelerate, it goes slowly first, then jumps into a fast acceleration and then drives normally. 

with best regards

Lasse Busch,

P.S I plan to retire this Nitro to a Sunday driver, and then lease a Toyota for daily commute.
