Jeep Wrangler Struggling to Stay Alive

Spark plugs look rich, and if you’re smelling fuel, I would say you have a bad sensor related to fuel mixture.

It ended up being the vacuum hose for the fpr

What made you suspect electrical over fueling (pump, filter, pressure regulator, injectors) for the cause of the sputtering?

[@ParkerMotorWorks]

I've been thinking about the fuel the past couple days because it is smelling awful of gas

[@franciscomolina5362]

clogged cat??

[@ParkerMotorWorks]

Ended up being the fpr boot

The pick-up in the distributor is probably bad, or there's another issue with the circuit concerning that sensor. A classic symptom of a bad ignition signal is the tach jumping around like that, as it's showing a momentary complete loss of the signal. If there's an issue at or after the coil, like plugs or wires, generally the tach will still reflect accurate rpm even when misfires occur.

Thanks for the suggestions I'll check those out

@ParkerMotorWorks you can get fault codes from the engine computer by doing a key cycle procedure and counting check engine light flashes. I recommend doing that if you can, and see if you have code "11". If you have code 11, it's almost certainly going to be a bad pickup inside the distributor.

That's really good info but we've found the problem. Uploading a little short on it now. Ended up being the vacuum line from the fpr to the manifold
