Your codes indicate faulty readings from the MAP sensor and Powertrain Control Module. Problems with either of these would mean the engine computer could not accurately determine fuel injection ratios, causing the symptoms you describe. When you take your foot off the gas, the engine cannot regulate the combination of air and fuel.

This could mean that the MAP sensor is bad, but it could also indicate some other miscellaneous fuel injection or ignition problems.

If you have an advanced scanner that gives you a readout of more than just the error codes (such as the actual senor readings) you may be able to isolate the problem and confirm it is the MAP sensor, which you could buy and replace yourself with the air of a repair manual. If you cannot isolate it as the MAP sensor or determine that it is the PCM, you will need to take it to the dealer, as the PCM will need to be recalibrated on their computers even if you install it yourself.

Barring the relevant knowledge or equipment needed to further diagnose the problem, you'd want to take your car to a mechanic you trust to work on Cadillacs - know that they can be a bit more complicated than their GMC and Chevy cousins - or to a dealer to check the systems.

SOURCE: i have a 93 cadillac deville and trouble starting

Change fuel filter, and air filter. After your change the filters hook a fuel pressure guage to the fuel rail. The spot to hook up at looks like a valve thats on your tire. Should be no less than about 35 psi. If fuel pressure is good and it still struggles during warm up. Look on the throttle body and see if the linkage can be adjusted or if there is a adjustment screw. All else fails change throttle position sensor.
Wouldnt hurt to put new spark plugs in if you havent already done so.

Have it scanned and look for codes first, but then fuel trim, O2, and MAS air flow readings. I'm going to guess it's running lean and you have an air leak in the throttlebody.

SOURCE: running hot temp gets to 220 and above.often shuts

When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.

===

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

===

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

SOURCE: 2001 Cadillac Deville won't stay on after turning

EIther the IAC or throttle postion sensor is dirty or faulty. Or leaky vacuum hose somewhere. As long as it is not missing and running weird, then you may have bad coil packs.
You can go to autozone.com and register for free online repair manual for your vehicles if you need it.

Dies when foot off gas


I would get another opinion on the alternator. There are tests that I am sure that autozone did not and cannot run. One is a load test, This would indicate if the battery is getting any electricity from the alternator under loadm diodes in the alternator could be failing. There is no way to adjust the RPM. IT should be around 800 on an automatic tranny in drive.

Car won't run without foot on accelerator.


its very important that the throttle body especially around the throttle blade be spotless clean or they will stall every now and then. then progress to refuse to idle at all. take off the rubber air intake pipe from the top of throttle body [has 3 torqes screws] open throtle by hand and look for carbon/grease/soot etc were the throttle sits when closed. clean with toothbrush and some caeb cleaner get all black off and dont forget the blade, both sides and the edges. scrub then rinse with carb cleaner untill shiny.spray some cleaner in the hole that is on top off the body to. that is your idle air controll motor port.put back together.it will be hard to start at first so hold gas pedal half way down untill it starts then slowly [real slow] let foot off untill you are no longer pressing it. put in reverse and let it idle there a few seconds then do the same in drive. that should do it. sometimes it may stall a couple of times when driving dont hold foot on gas just let it die then restart this allows the computer to readjust its idle stratagee

The car runs fine but will not idle if your foot is removed from the gas pedal


you could have a fuel filter problem. This is the likely cause. You can also have your computer scanned at a parts store to see if it has any codes stored in it. HOwever, I think the fuel filter is your problem.

I have a 2002 Chrysler Sebring and i just had the starter changed and now it shuts off when you take your foot off the gas pedal? it drove fine for about 5 mins but now when you take your foot off the gas...


try unhooking the battery and cleaning the throttle body. Open it up and clean it with an old tooth brush and carb cleaner, now hook up the battery. crank it up, hold the throttle halfway down until it clears up and runs smooth. now slowly let off the gas and it may idle ok. If not you may need to take it to a shop and have th e"adaptives and the Idle Air" rest using a scanner.
