Question about 2005 Chevrolet Tahoe

1 Answer

5.3 Litre engine sarts running rough when AC is on & white exhaus

When we turn on the air conditioner, the engine starts missing and running really rough and the white smoke comes out of the exhaust. You can turn off the air conditioner and the problem goes away after a few minutes. Also the cooling fan comes on when the vehicle is sitting still without the engine on and runs the battery down. Do you have any ideals?

Spitting sputtering


These things are notorious for having crank sensor failures. Not too expensive and not too dificult to replace. I would try that first.

Large thump noise and wouldn't start. Then got it started and car was missing really bad and white smoke coming out of exhaust when I accelerated


Your car has what is called a blown head gasket. The thump you heard was the coolant in the cylinder. The white smoke you are seeing is the coolant leaking into the cylinder and burning. that is well is what is causing your rough running problem. I hate to be the barer of bad news but this can be a costly repair. Usually around 1200.00.

Ford focus tdci not starting and white smoke coming out of the exhaust


It is a clear case of the glow plugs malfunction. It had happened with my neighbor who tried to start his diesel focus one day.
Even jump starting with another battery didn't solve the starting problem.

You could also check the EGR valve for damages and if you want to save a couple of bucks, then go in for used parts for the focus from Good used Focus Stuff

My 97 honda accord is blowing white smoke and running rough then i went to start it now it wont start


Sounds like either a blown motor (rings need replaced) or a bad head gasket or cracked head.
If the rings are bad your car would have felt like it was losing power because the engine will no longer have the same high compression that it's required to turn the wheels. You may have heard your engine knocking or seen a light blue colored smoke coming from your exhaust as a result of your engine burning up oil in the combustion chamber from the rings leaking.
If your head gasket is leaking or your head is cracked you'd likely find milky looking oil when you drain your oil from water/antifreeze being mixed in and noticed a white smoke coming from your exhaust that is actually water vapor coming through the exhaust.
If your car was running rough when you last shut it off try pulling all of your spark plugs and either cleaning them or replacing them all. A bad head gasket or bad rings can both foul spark plugs. A car will run rough with 1 or 2 fouled plugs, but once enough foul it will no longer run at all just sit and crank over. If changing the plugs get's it started for ya, check your tailpipe first for water, if nothing, change your oil. If no signs of water/antifreeze or milky colored oil then it's probably rings.

White Smoke that smells liek fuel, but not overheating


you're probably burning coolant. headgasket, cracked or warped head, intake manifold or gasket, or cracked block are your sources. Take it to a care car service to have it checked. Whatever it is, it's hard to diagnose just by the exhaust color. I had white smoke coming from the exhaust of the family van, it was a cracked block. That can certainly cause a multi-misfire. So have an ASE certified mechanic look it over, it could get expensive!

Car stalling with air conditioner on


hello, it sounds like the ECT (engine coolant temperature sensor) is failing, the sensor communicates with your computer and has affect on fuel usage, it is common for bad sensor to allow too much fuel and cause cylinder flooding, this in turn will lower cylinder compression and cause miss, black smoke, check engine lights, easy too overlook without propper diagnostic equipment, easy too change and fairly cheap! good luck, marty

OK, fast! Check the exhaust for rotten egg smell and pressure. Exhaust should stop immediately when engine is turn ed off

Backfiring, rough idel


I would check the exhaust pipe a little closewr. White smoke can also mean a blown head gasket. Check the tail pipe to see if moisture is present. Also check coolant level. A blown head gasket can also cause related problems.
