2002 VUE 3.0L
Default 3.0 miss fire hwy speed

Hello. I just inherited a 2002 VUE 3.0 AWD. 96 k . To make a long story short , I am the 3rd family member to have owned this and its problem. At a steady 50 mph, when trying to accelerate then back off and then accelerate again, engine light flashes, multiple cylinders, 1, 3 ,4 continuous miss fire. Engine shaking and losses power. Pull over or just put in neutral, shut off engine, restart. All is good except engine light on. Easy to recreate. My son has put in mass sensor and did the vacuum chamber springs. codes p0301,03,300. Looking for a little advice on what could be going on here and where to start looking.

Thanks

REWARD EXCELLENCE!

Does your misfire only occur at 50mph? Can't get it to misfire under the same acceleration conditions but at 40 or 60 mph?

Ever change the plugs? Coil packs?

Checking/changing the plugs and coil packs is a very good suggestion on this engine. Especially considering the fact that these V6's are known for leaky valve covers at relatively low miles that tend to foul the plugs and coil packs.

I noticed that you said you only have 96K on clock, which is pretty low for a 15 year old car, but you're the 3rd family member to have this Vue.

Were there times where this Vue sat without being driven for extended periods of time?

I ask because I'm in the process of getting an '03 3.0 Vue back on the road that sat for over a year with the prior owner and I was fighting a nasty misfire that would show up intermittently. Sometimes at idle, sometimes at speed. There wasn't really a whole lot of rhyme or reason to when it occurred.

After a full tune up (plugs, coil packs, valve cover gaskets, thermostat, timing belt, etc.), and a fresh tank of gas, I was still having issues with occasional misfires.

My last ditch effort since pretty much everything on the ignition side was brand new was that it had to be a fuel related issue. I ended up draining the tank using a Tech 2 and replacing the inline fuel filter, then refilling the tank with non-ethanol premium gas to be safe.

Since I emptied the tank and replaced the fuel filter, I haven't had a single misfire. Running regular unleaded in it now without any issues. I'm guessing that this engine is just particularly sensitive to ethanol, especially if the gas isn't particularly fresh.

If the fuel filter has never been changed and your Vue has sat for any extended period without being driven, it might be worth a shot to drain the tank to get rid of old gas and replace the filter.
