Nah... Robert Hofland,

The security key either works or it does not...

If the "DEALER" actually has a MECHANIC around...
That would a NICE (albeit unlikely).

YOUR Dealer ...
(In my opinion: needs a little integrity and / or a brain)...

Your can get "FREE" reads to get the
Diagnostic Trouble Codes (DTCs) pulled out
of your On Board Diagnostic System...

Don't buy anything... ESPECIALLY not Oxygen sensors...
just get the codes READ-OUT...

Come back here... We have some pretty good experience...!!

>> If it only does this when it is cold...

>> or when it has been standing...

Point to completely different troubles... but both in your

Getting those codes is PARAMOUNT.

Exhaust shops, parts stores... even some mechanics...
If it is something simple... You might be wise just to get
it fixed... or diagnosed & fix it yourself...

Pretty sure you are BETTER OFF not letting the
"dealer" continue at VERY BEST... being incredibly INCOMPETENT... dishonest... (creep... etc.
(in my opinion)).

Try it... Big savings... You will be proud.

Ignition immobilizer probably needs to reprogram is the security light on.
I am not sure that your car has a fuel switch.
If the car has a fuel cut off system, for you to reset it, the manual says to turn the key to the acc setting n let it sit for a few seconds then turn key off then turn car on.
Fuel pumps do go on these and from what I remember, pretty easy job if you have some mechanical ability.

Are you saying the water reappeared while the car was still in the garage? Hope this is not true, as that would most likely be related to the heater core or plumbing, but I thought all that was on the passenger side. If you mean after putting the car back outside and in more rain, possible cowl vent tube leak, windshield leak, or door vents at bottom edge blocked with debris.

This is normal if your A/C doesn't work. When set on defrost the A/C kicks on and off to keep the fog from appearing. the fog goes away once the heat inside reaches a certain temperature. Unless the drain is clogged and the plenum is holding water. Do you have ice on the inside? clean the drain. It's on the passenger side, near the bottom of the firewall. A rubber tube coming out, that goes to nothing.

Fuel pump maybe, clogged fuel filter maybe....could be other problems with sensors on the engine starting to have intermittent problems after things warm up in the engine bay. Best to have someone competent check it out for you instead of throwing parts at it. Do the easy stuff first like maintenance items like the fuel filter? Ever changed it? Might be codes stored in the computer system on-board that will help a mechanic diagnose the problem.

Without knowing if there has been any "Cooling System " work on car. (1) U could have a stuck thermostat, air in cooling system, water pump or impeller damaged. (2) top hose is coolant from engine TO radiator (3) bottom hose is coolant from radiator pulled into engine. (4) engine is WARM but is it RUNNING ? (5). Also, if radiator/coolant tank cap is left off , system is unable to pressurize , there fore "SOFT HOSES". all this is guessing without more info. bigAl
