I have an issue with the check engine light flashing 4-5 times then goes off. I live in Colorado and it typically comes on when I am pulling up an incline going 75ish and RPMS in the 5,000 plus. When the light flashes I let off the accelerator and the flashing stops. Has also come on going at slower speeds but still high RPMS. Started a year or so ago when pulling my pop up camper over the passes. Last trip the check engine light stayed on after a long pass climb at about 40 miles per hour. Repair was a miss firing in 6. But, the next day lights flashed again without camper. Does not happen all the time. It was typically only when pulling a camper but now do not need the camper. Brought back into the shop and since there are no messages they can not tell what is going on. I have a 2015 with no engine upgrades but do have 35 inch tires and a 4" lift. Not sure if it is related but since I bought it almost 2 1/2 years I do get a strong gas smell when four wheeling at the slower speeds and sometimes when just driving in town. I smell it when I stop the vehicle or pulling up a steep rocky climb. This was happening before any upgrades at all. Thoughts?

When the light is flashing are you checking your gauges ?

Is the engine temp, tranny temp, oil pressure, battery voltage all ok when the lights flashing

You should never smell gas. Never. Clearly, there's a leak somewhere. No way of knowing where without being there looking, but that's what to start with.

Hi gmcojeep, actually having exactly the same issue as you with the check engine flashing while going on a vertical road on high RPM’s; i drive a 2015 Rubicon HR with 35 inch tires and 4” lift kit also (same as you).

Have you found any solution for this issue?

I don’t know if it has to see with regearing the Wrangler.

I'd expect that there is a code stored (even though no check engine light on) that is accessible with a OBD adapter such as the OBDScan MX+ (that's a good one, but you can certainly go cheaper) and program that's specialized for Mopar vehicles such Jscan, AlfaOBD, or DiagFCA. That would be my first thing to check.

Generic OBD software (such as OBDLink which is free with the MX+) will likely be able to tell you the code as well, but the programs above can be more specific and also can help with further diagnosis and testing. If there's no code the next step would be to log data using one of these apps and see if you can replicate the issue, then dig through the data.

The Jscan website lists its recommended OBD readers as well.

not trying to sound like a Richard here.
but you are describing driving an under geared stock jeep with 35's .
hauling a camper up hill over high altitude passes running 75mph at +5000 rpms??

this is not normal driving conditions.
my first guess is the engines computer is trying to prevent damage from being done.
there is no code for that.

as for a gas smell ,, does your oil smell gassy?
under normal conditions you should not smell gas anytime
I wouldn't be surprised if it was detectable immediately following such a high load extended pull .
