The firing order for ... Related searchesThat is correct Shawn. Modern engine controls are so precise that the old skool spark plug reading is no longer relevant. Until it is. In this case, your darker porcelain might be big clue. *See below. Yes. Drive-by-wire will park throttle open a bit to be prepared for next startup. It's one of your Variable Valve Timing actuators, activated by oil pressure, so they do tend to leak in o-ring sealed apps like this one. A lot of variables play into misfire diagnosis, most of which are unavailable to us here. You've done q great job with your methodical approach here, and effectively ruled out ignition miss here. Nice work. Bad coils typically misfire under light loads on the road, not at idle. Two things normally create idle misfiring that goes way with RPM:
*Sloppy injector spray could cause this symptom, and that guess might be supported by your darker spark plug coloring. But I don't think so (Tim). However, fuel delivery could still be suspect, volume specifically, especially if your Jeep suffers poor off-line acceleration. Chrysler has issued a TSB about this, with low fuel volume the cause, and pump module replacement the cure. Often times, the last injector on the rail will flow the least fuel. Yup... 2 is last on that rail. Base engine usually means compression loss, unlikely here cuz it just don't happen much anymore at 55K, and when it does, it's usually not intermittent. Unless it's "variable". A sticking Variable Valve Timing rocker might cause this random, idle misfire. Notice that oil-seeping actuator is right adjacent to your #2 cylinder, the first rocker likely to stick if contamination were an issue. This could cause higher intake valve lift at idle after coming down from higher RPM. Simple fix might be cleaning of the VVT Solenoid screens and a fresh oil change using spec'd grade oil.

Mar 26, 2018 Does anyone know how the 3.2 V6 cylinders are numbered? I'm troubleshooting a P0304 and trying to determine where cylinder 4 is. Thanks in advance. 2015 Jeep Cherokee Trailhawk, 3.2 V6

Discussion Starter · #3 · Mar 26, 2018 I had assumed incorrectly that the #1 cylinder would be towards the front of the vehicle. Yes, I plan to fix it myself. Thank

I don't believe that firing order for the 3.2L. That would make the engine very unbalanced. Joined Jun 6, 2015 · 12,751 Posts
I don't believe that firing order for the 3.2L. That would make the engine very unbalanced. Apparently a lot of V6s have this same firing order, from different car manufacturers. Just look up firing order for the 3.6 Pentastar, as it is much more prevalent than the 3.2 (both engines are identical except
for a larger bore on the 3.6). Joined Dec 9, 2016 · 1,010 Posts
Sorry for bumping this thread, but I have a question concerning the firing order, especially when it says right and left banks. Ok, fine. But based on the orientation of the car, which bank of cylinders is in the front of the car, versus towards the rear of the car? Is is suggesting that the right bank is towards the rear of the engine, and
the left bank is in the front of the car, based on that photo from the Factory Service Manual? I got a P0302 error code a couple days ago for the #2 cylinder misfiring, so I want to be sure before I start deciding how I want to go about this.

Think of it this way : sit on an engine facing pulleys side (not flywheel side),
and you have your left and right under you. In a typical longitudinal engine configuration with pulleys up front, when you sit in driver's seat (LHD) you have the pulleys up front so left bank is on your side (driver's). Most (all ?) transverse mounted engine have the pulleys on the left when you are standing in front of the car, so if you sit on the engine with pulleys in front of you, left is bumper side and right is firewall side (or rear side when you stand in front of the car). Below is a
pic of the 3.2. Dipstick in closest to bumper. Hope that makes sense 111.1 KB Views: 5,096 Joined Dec 9, 2016 · 1,010 Posts
