In reply to Brandon. Scan the codes and have a mechanic listen to the noise.

In reply to Alfred.

Engine oil gets dark pretty much as soon as you drive away from the shop. That doesn’t necessarily indicate a problem.

Does the idle sit above 1 even when the car is fully warmed up? Could be a vacuum leak, maybe. You could try pulling the plugs to see if that tells you anything else. Make sure you’ve done the basics like change the engine air filter and fuel filter within the manufacturer recommended intervals.

Hi.
The RPM of my car stays above 1 at idle. Black smoke and soot comes out of the exhaust pipe. The fuel economy has become very poor. The engine oil becomes black within 700 miles of driving.
It’s a Toyota Corolla 2006 model.

What could be the problem, please?

In reply to Jason. Also check if your thermostat is working properly.

Hi so i have an expedition showing codes for 4 diff oxygen sensors. 2 camshaft solenoids . mass air flow . we replaced all of them plus did oil change replaced fuel pump and still the codes wont go away . it did get better gas mileage after replacing sensors but started running rougher . issues are : rough idle , ghe car shakes or jumps after sitting for a minute , it has no acceleration and aweful gas milage . we did replace them backwards at first and it seemed to get betted still big then put them in the right way and its still doing the same thing and has the codes . yes we reset it / also it dies if going really slow and you have to cautian and put blinkers on and restart

Is this the same for a diesel engine? I have the engine light coming on and off and was told it was the Oxygen sensor. Unfortunately there are no spare parts in Australia for my car and have to keep driving with this problem. Will my engine be damaged eventually?

In reply to Amith. That is often the solution, yes, but not always. Is this the only code you're seeing?

In reply to Austin Navas. Sorry, we do not sell anything directly. We do link to several third party vendors though, so perhaps one of those vendors may have what you need.
