sounds like a bad relay It is the blower controle module. Been there done that.
The engine could stall when you are on the road, causing a traffic problem.
A bad EGR valve should not cause the engine to not start. There is most likely another problem that is causing the engine to not start.
no as long as the engine is running the pump needss to remain on
Not a problem unless you plan on running the engine... Of course it is a problem. An oil filter is mandatory for the life of the engine.
Something has gotten water on or in it, and is causing a misfire. You need to find what is wet and dry or replace it. The plug wires, coil , distributor cap are all places that could hold the problem. If you have the code checked it should show which cylinder is the problem.
No it will not. YOU have another problem.
It is not supposed to be on when engine is running unless there is a problem.
No, an engine idle RPM being not zero is not a problem. If the idle were zero, the engine would not be running!
The fan is on a thermostat, causing the fan to run if cooling is required, even when the car ignition is turned off. Having said that, if you notice that the fan is running long after you've shut the engine off, you may have a problem!
Fix the problem causing them to be on.
The power steering module has lost the engine speed signal. This is normal if the engine is not running. If the fault code comes up with the engine running, you have a problem.
Most likely bad intake manifold gasket. When the engine is cold the engine shrinks which unseals the intake and allows a small amount of unregulated air into the engine causing it to idle rough. as the engine heats up it expands sealing the leak causing idle to improve. You should also get lean codes from the computer as the engine is running to lean. Very common problem with the DOHC engine. See "Related Questions" below for more
