I have a 2000 impala with the 3.4 and 160,000 miles on it. The other day white smoke started pouring out of the exhaust and the #6 cylinder was not firing. I changed the head gaskets, upper and lower intake gaskets and the valve cover gaskets. anyway, when I got it all back together and cranked it up, it ran fine for about 10 mins, then it started to run really ruff. The next day, which is today, I crunk it up and it was still idling super rough and eventually cut off and would not crank back up. I took the ignition control module in and had it checked. They said it was bad so I bought a new one and put it on. This time it cranks up, but still idle ruff and I get p0300 random cylinder misfire. the coil pack and plugs and wires are only 2 years old. Thanks

Will only stay running on revs over 2000rpm if I take foot of peddle it cuts out also white smoke from exhaust

What is year--make--model?
Are you losing coolant? The white smoke may be coolant in the combustion cylinder, possibly caused by a head gasket problem. If head gasket problem, fix that first.

With idle issues, clean/check anything that has to do with idle air system. Any applicable trouble codes?

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.

White smoke won't start

Has the vehicle been overheated recently? White smoke from the exhaust indicates the combustion of antifreeze, which happens when either the cylinder head is cracked, or the cylinder head gasket is faulty, allowing coolant to enter the combustion chamber.

Excessive exhaust smoke on the first start of the day

Sounds like the valve guides are leaking oil into the cylinders, or there is a coolant leak somewhere. Usually white smoke is coolant but could be oil.
Are you adding either fluid often ?

I have a 1998 ford windstar V6. and im having lots of white smoke pouring out tail pipe with lite water what can this be

It's possible that the white smoke you are seeing is from coolant entering the exhaust, however, I would think that the engine would also be running rough or be difficult to start should this be the case. I would start by checking the coolant level. If the level is very low then it's possible that you have a head gasket leaking which is allowing coolant to enter a cylinder and then be forced into the exhaust where it will turn into a thick white steamy/smoke that takes a while to dissipate after it exits the tailpipe. Whatever the source or cause of the smoke is, it's possible that it could cause some serious engine damage so you should have it checked out as soon as possible.

Fuel injectors were repaired for 400 bucks and white smoke is till pouring out of my exhaust and my gas usage is still above normal did I get ripped off. The mechanic at the garage said it would smoke...

I am corncerned about the smoke being white.
White smoke usually is from moisture in your exhaust system.
The moisture comes from water getting your engine cylinders by one of several ways.

1 Blown Head Gasket
2 Cracked Head
3 Cracked Cylinder

A rich gas condition causes black smoke
Oil burning causes blue smoke

Check your coolant level to make sure your not losing it into the engine vis a crack or bad gasket.

Good luck

Misfires in Cyl. 5 and 6, after changing problem continued

white smoke indicates the engine is burning antifreeze, you could have head gasket issue, if thats the case the antifreeze is getting in the cylinders and the engine is burning it. could be a stuck exhaust valve( i doubt it). find out from ford what that code indicates, that would be a better clue than tearing into the motor

Double check your firing order and make sure all wires and hoses are plugged in good. when you pulled the push rods out did you make sure they went back exactly where they came out because there are 2 different lengths.
