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?

White smoke comes from tailpies while excelling traffic light.


Is it a lot of white smoke? White/Gray Smoke: White exhaust smoke is an indication that coolant is burning in the combustion chamber. These are possible causes:
Cylinder Head: A crack in the cylinder head (around the coolant jacket) will cause coolant to enter the combustion chamber.


Although for some cars white smoke is normal, as long as it is not super excessive.

Smoke from engine


Is the smoke white or blue? If white means that you have a leak of water or antifrezze into the combustion chamber. If blue, replace PCV valve, and air filter.

Heap of white smoke on startup but not always


White smoke usually occurs when there is not enough heat to burn the fuel. The unburned fuel particles go out the tailpipe and typically produce a rich fuel smell. It's not unusual to see white smoke in the exhaust during cold weather until the engine warms up.

Faulty glow plugs or control module can cause white smoke on engine start up.

Low engine cranking speed may also produce white smoke.

If white smoke is still visible after the engine has warmed up, the engine may have one or more bad injectors, retarded injection timing or a worn injection pump.

Low compression or air in the fuel system can also be a source of white smoke.

White smoke from the exhaust when I start the car


Hi!

What type of smoke can you see---

white smoke-
If you see a wispy, lingering white smoke that has a bittersweet smell, this is an indication that your car's engine coolant is leaking into the combustion chambers. This may be due to a leaky head gasket, or in a worst case scenario, a cracked cylinder head.

Make sure to take your car to the shop right away to get it fixed.
Thick white smoke---
If your vehicle is belching white smoke upon start-up, it is a sign that transmission fluid is entering the combustion chambers, possibly though a vacuum tube that connects the engine to the transmission.
This type of smoke can be confused with the normal puff of steam during start-up. If you are not sure, have your car inspected at the shop.

Blue/White Smoke--
A blue/white smoke is an indication that oil is being sucked into the combustion chambers through the valve guides. A quick fix for this problem is by replacing the valve seals. Valve seals are small, umbrella shaped pieces of rubber.

Do rate the solution.

Thanks
Rylee.

My truck blows white smoke


Hello!
There are two differnt reasons for black and white smoke coming from the tail pipe.
Black smoke means fuel runs rich (car getting to much gas). Check fuel pressure/air filter.
In some cases the white smoke means car is burning oil or transmittion fluid. Have tem checked/replaced.
If you can feel a smelly smoke it can be catalytic converter.
In a worsest scenario if car blowing white smoke it can be engine coolant is getting into an engine cylinder from a bad head gasket ,or a warped/cracked head. So you need to keep your eye on coolant level and check your engine for overheat. Also might be good to check your oil for traces of coolant (on a dipstick it would be a milky substance mixture of oil and coolant).
Good Luck
