Hi Maxine: Here's a link that should help. http://caddyinfo.ipbhost.com/index.php?showtopic=44009 heers.

I know this might seem silly but seen it a number of times in the shop, make sure nothing like double floor matts or newspaper is causing your stiff gas pedal. Open hood with engine off and manually play with accerlator and see if it binds. if you have one person in seat and another under hood that's under way of checking if its a mechanical or electrical issue

Look under the hood. you should find a part under there with two metal thin lines connected to it so that when you push the gas pedal, that part moves up, when released, it should go back down, have someone press the gas pedal and look for it right on top of the engine. is there something blocking it? wiring harness, etc.?

Did anyone scan the PC or check the emissions? Coolant sensors are tricky . check the coolant level to start have the emissions ckd & the PC scanned. Im sorry, don't go to the tech with the answer, tell them your problem ! No Start Cold. Very common. Could be vacuum leak, sensors and the list goes on. Those are the most common though. Good luck

The clock spring assembly was most likely damaged during removal/assembly of the repairs. This assembly controls the airbag/horn/steering wheel functions. It is not that hard to change if you have a steering wheel puller to get the steering wheel off. Here is an exploded diagram. Hope it helps. The very top of the diagram is the clock spring assembly and it will be the first thing you see when the steering wheel is removed

If it wont crank over the battery might be to weak to start the car but just have enoughf juice to run the electronics in the car.
Or the starter died.
1st charge the battery up and see if that works.

do you mean oil light. if so check the oil level on the dipstick and how long has it been since your last oil change, as dirty oil can cause the light to come on if its very dirty or low. if both of these is good then it may have been some dirty that momentarily plugged the sending unit and turned on the light. is there any rattling noise with the motor running. if so have the oil pressure checked.

Two on the engine and one on the transmission.

You have a coolant recovery tank with a radiator cap that is located separate from the radiator itself, I think it is on the passenger side of the car under the hood.about halfway between the grille and the windshield. Find the tank, and remove the cap very slowly while the engine is off and the motor is cold. It may still have high pressure, so watch out. You should see the coolant within an inch of the radiator cap inside. If you want to see a picture of what the recovery tank looks like, pull it up on e-bay and type in your year and model of car and search e-bay motors. Be blessed.
