Misfiring after 475 miles

[daniellelaven022]

So far everything is driving nice, but everything drove great til 1300 miles before all this. We want to stay hopeful though!! We dropped rental off and looked truck over before we went in to go over paperwork and get key. They really did only drive it 5 miles total the whole time it was there.. the paperwork said they put 61 miles on it… I made them correct the paperwork so it reflected the correct miles. Kind of disappointed considering their service director assured me he was going to have them put miles on it before we pick up. I do want to have alignment checked when we get home it’s pulling a little more to the right then it should in my opinion, but considering what we’ve gone thru to get this thing back that’s minor to me I also did not see anything about a PCM update so I asked the advisor working today to have their service director call me Monday about this update he told me they were doing. As of now guys this is all I have for you. I will update y'all if anything comes up but so far she’s doing great. I’m a happy gal!

My truck pulls to the right also, one of my coworkers said certain tires will do that till they are broke in. I don't know though so I told my salesman, he said bring it in. I only have 105 miles on mine so I thought maybe my coworker maybe right. He use to run a service and mod shop

Mine pulls right a bit on the highway. But, don’t want to jump the gun on an alignment, as they will often “mis-align” a vehicle to cure a customer complaint.

Remember, most roads are graded right, so a slight pull to the right is normal unless there is a compensating factor “programmed” into the power steering.

I’m at almost 1400 miles, so a mis-alignment would show in tire wear. So far, my tires look to be wearing evenly,

It seems to be a little more then the natural pull the steering wheel is a smidge off to the right. It’s not bad enough for me to worry at this point as I may be doing wheels, tires and a level kit which they would need to align when I do those. So far everything is great though

This is supposedly the fix for pulling to the right.

Just thought I’d update yall it’s been a little! Everything has been great just got her tinted yesterday ordered wheels and tires! I did pull her in from work tonight and found a couple spots of coolant in the ground so will be making an appointment at my local dealer Im guessing maybe the thermostat or coolant hose is leaking. I’ll keep y’all posted once I know more, but otherwise I do really love her!

Update on the coolant leak. It’s transmission heater coolant line that is leaking. Parts ordered once they get in I’ll be dropping my truck off again for replacement. Parts are looking to be about a week out. Picked her up in the mean time and dropped her off to get her new wheels installed!

It never ends ey?

It does feel never ending I did get the wheels installed today though, she’s looking reallll good on a positive note

Dig the look! Tough to tell from the angle of the pic, are the wheels zero offset?

 

[daniellelaven022]

Thank you!! +10mm side note the caliper did need to be slightly grinded in order to fit.

Appreciate the info, I’m looking to stay with an 18” wheel as well.

This was my alignment and it is at the dealer and it is all fixed now but now waiting for a new O2 sensor, I just really hope its not a blown cat

Looks good. I was contacting KMC to see what wheels they had in an 18" that would fit, and I wasn't thrilled with the options. I wanted these or the IMS. Seeing that you made yours fit gives me hope I can get the IMS to fit.

Sorry to not follow the thread too closely - but if someone is diagnosing misfires or rough running truck.... there is a bulletin from Mopar/FCA/Stellantis to check the connection of the airbox, MAF sensor, and intake plumbing. Basically it's a poor/ incorrect MAF signal. So the truck uses the maf sensor for load calculation (ignition and fueling) So if you've been messing with your air box - and now you have misfires - check it out.

That is what my truck is in service for now. They thought it might be a bad O2 sensor

There is ALSO one for the lambda sensor wiring pulling out of the sensor. If you look at the lambda sensor that connects near the inlet to the turbos - it's too short from the factory and it's pulling on the pins. They even have an acronym for the pins coming out of the connector. I would think that's what's happening on yours.

Lots of new info for in here in case the new PCM doesn't fix my truck.

it's rarely the PCM. Bosch MG1 ECU's are pretty stout units.
