Hi

I am assuming it is a petrol engine. I experianced the idle fluctuations / surge and cleaned the trottle body with carburetor cleaner or trottle body cleaner.

On the top of the intake manifold (front of engine) there is a +- 8mm rubber pipe (almost in the centre). Remove clamp and pipe when engine is at normal operating temperature and spray about 80ml into manifold via connector of the rubber pipe. Replace pipe and start. Staring would be difficult and smoke will appear from the exhaust. Drive vehicle and repeat cleaning procedure.

What do your car do when your o 2 sensor is bad?

Technically, when there is a fault such as an O2 sensor failure, the engine management system (the computer) goes into "Open Loop" condition. This mode is normal while the engine is warming up but causes poor fuel economy and reduced performance. Once the engine has warmed up to normal operating temperature it will switch to a Closed Loop condition. You always want the system to go into closed Loop under normal conditions. O2 sensor failures will sometimes cause the "Check Engine" light to come on, sometimes not. It is always best to have the system checked for fault codes if you suspect a problem like this.


What is blowby in an Internal Combustion engine and what can happen if it increases above normal level?

Blowby is the result of the piston rings not sealing properly against the cylinder walls any more allowing exhaust gasses to enter the crank case. This results in reduced compression which translates into reduced performance and fuel economy. It also results in more frequent oil changes as it leads to increased oil contamination. Left unchecked it can further reduce overall engine life due to contamination of the oil. Repairing an engine with excessive blowby will generally require a complete rebuild along with machine work on the engine block.

What causes your car to drive really slow?

There are many different causes of poor vehicle performance. Here are some examples. If the engine RPMs are high but the vehicle will not reach normal speed then there is a problem with the engine's connection to the drive line. If the engine is running rough it will not be able to produce a normal amount of power. If the exhaust is plugged the engine will not be able to breath. There are many more possible causes.

Would it hurt to just take your thermostat out because my car is getting how even though i have new water pump radiator hoses?

the car will run with no thermostat installed but performance will be affected. the thermostat not only opens when the engine gets to preset temp but also closes until the engine reaches normal operating range. when the engine is cold either the choke or the fuel injection system richens the fuel/air mix. smoking, fouled plugs,and reduced gas mileage might result.

Are 401K contributions tax deductible?

401k's are not tax-deductible in the normal sense of the word. However, since normal 401k contributions are made with pre-tax funds, taxable income is reduced. As taxable income is reduced, tax is then reduced as well.
