Hello All,
I have a 2005 Nissan Titan 5.6 SE with 150,000 on the odometer. Last week it got down to about-5 here in Minnesota. The truck wouldn't start so I attempted spraying starting fluid in the air intake with no results. I didn't think it was the battery so I didn't immediately replace the battery. I replaced the battery today and it started right up. However, it spewed thick white smoke that smells almost like the truck is flooded. I let it warm up then drove it around the block. Near the end of the drive, the truck's idle became increasingly rough and the engine became really quite even when I pushed on the gas. It didn't fully die but I turned it off and parked it. Any suggestions or ideas about what may be wrong? I did get some starting fluid on the MAF sensor.. could this make a difference?

This is the first starting problem I've had with the 3 Nissans that I've owned.

There may be a couple unrelated issues going on.

Freezing temperatures can greatly diminish your battery's performance. It can also crack engine blocks from expanding coolant.

I hope I am wrong, but if the amount of antifreeze you had in your system wasn't enough to prevent freezing, it's possible that something broke on the engine and is causing coolant to seep into the cylinders or exhaust.

But it's not best to jump to unnecessary conclusions. It's possible what I said is the problem, but it may be something less catastrophic.

Hi, Thanks for the response. I have an update. After finding a thread on here, I cleaned the PCV Valves and all of the smoke went away. I was shocked that this was the only problem. There was a bit of brown sludge in the PCV valves.

yup, that is normal with a high mileage engine, or an engine that was not entirely maintained.
even low mileage Titans have oil in the hoses that gets sucked in.

in your case, the starting fluid may have reached in those areas and washed some of the oil film from the interior of the hose or valves, creating the smoke upon start up...

a flooded engine, or engine with washed down cylinders due to over cranking/flooding if the pedal was not depressed all the way down to put it in flood mode could very well have a crap load of smoke when it does finally restart.

That's great news man! Could have been so much worse
