Hi Graham,

This means that your engines computer detects that your engine is not running as efficiently as it should. You should get your cars computer scanned and check the codes. It will give you a starting point to determine whats wrong with you car.

Hope this helps and good luck!

sounds like a engine sensor i'd guess at the crank sensor but to be sure you would need to get the OBD codes read , this will give the exact fault so wont waste money trying sensor(s) on a hit an miss basis,you can buy a code reader online not expensive just make sure it covers your vehicle make then you have a valuable diag equipment for future use

check fuel pressure

could be a problem in the wiper motor it may have a short

There isn't a car out there that likes to be put in drive as soon as it is started. Mine especialy. I give it at least 30 seconds to warm while I am adjusting evrything and away I go. Runs like a champ. Let it warm up for a couple of minutes from a cold start.

You need to make sure you have a good drive belt and verify that the tension is working,if all seems normal then get the alternator or the wiring to it tested.

you have problem with tank mybe is dirty and you must check fuel filter and fuel pump

Yes pull the cooling fan relay in the fuse panel. It might be bad.

Have the Idle Control valve cleaned or replaced.
