The service engine soon sign came on awhile ago. I immediately took it to a garage and they said they can't find a code. My mechanic friend checked it and found a lean combustion condition. What could be causing this issue and what can I do about it. This yellow service engine soon light is driving my nuts!!!
View 16 RepliesOn occasion, my 2003 Cadillac Seville SLS will indicate that the car is low on oil and I should stop driving. When I checked the oil, it has never been low. Prior to this happening, the gas hand began to dance between 1/4 of a tank and a full tank. I am not sure if these issue are related or if I have two separate issues.
View 2 RepliesI have a 2001 seville. The problem that I have is that the abs and traction icons come on the dash sporadically. When this happens the ventilation system shuts down. When the lights go out ,the ventilation system works fine. The dealership tells me that the two systems are not connected. They tell me that I need a new module. I would like to hear other diagnoses of the problem and repair.
View 1 RepliesI have a 2004 Cadillac it started to miss when your idling, a check engine light when on and it was #5 plug not firing so I changed the plugs in front 4 of them and also bought a coil pack and replaced that, but it still misses. What else can I check before thinking its a sticky Valve or internal engine problems.
View 6 RepliesI have 2002 Cadillac Seville SLS. From time the icons for the brake and abs do not go off after the car starts up. I'll be driving for anywhere between a few minutes to an hour or so and they well go off and an audio tone goes off. Sometimes they will not come back on for the remainder of my trip, at other times times they will appear again then go off again. There is no indication that there is anything wrong with the brakes. Also, when the icons go off and the heater is on the fan will accelerate. What may be going on?
View 1 RepliesI have a 1998 Cadillac Seville STS which has recently developed an intermittent stalling issue. Here are the details:
Happens occasionally when I'm slowing down or coasting, such as turning into a parking lot or going around a sharp entrance ramp-Has not yet happened during acceleration-No bucking or jerking while accelerating-No apparent warning that it is going to stall-Has happened once each of my last two trips
The first few times it happened my fuel level was pretty low, and one of the times I tried several times to restart it and it would start but die right away. I managed to get it started again, then I filled the tank and tested the fuel pressure at the rail, and I got 45-50 psi with the key turned but without the engine running.
After that time, I have not had any difficulty restarting it when it stalls. I held the valve in basically the same position that it is installed (meaning I didn't turn it upside down) and sprayed in the opening with throttle body cleaner (not carb cleaner). I then used a "pipe cleaner" to clean the inside, and I also worked the plunger up and down after I sprayed it.
I had a few "false alarms" in the past thinking it was fixed, so I wanted to wait until I was sure before posting. I now have to lose the habit of constantly glancing at the tach to see if it's about to stall. It would be interesting to know why cleaning the EGR valve fixed it.
I have a 2003 Cadillac Deville with about 120,000 miles on it. The SES light came on and I had some maintenance done at STS. The light came back on the night I picked it up. I took it back the next day, they said it was related to the transmission and they do not do transmission repairs. They cleared the light and said if it came back on they could flush the transmission and maybe that would take care of the problem or they suggested I should take it to a transmission repair shop. The error codes are p0741 & p1860. Once in a while at the beginning of a drive I experience a sluggish acceleration, it does not last long( a second or 2) and then runs fine for the remainder of the drive.
View 6 RepliesMy car is idling rough and the Service Engine light blinks on/off continuously. I ran the codes and they are P0301, P0401 and P1258. What this could be? I changed the plugs, wires and ignition coils about a year ago. Catalytic converter was replaced around the same time but the O2 sensors hasn't been changed. Could that be the cause?
View 1 RepliesAbout once each summer on a hot day, my Cadillac Catera won't restart until it cools for 15-20 minutes. I turn the key and the dash idiot lights come on but the starter does nothing. It only happens rarely and only on a hot day.
View 1 RepliesI have a 1993 Cadillac STS which I just purchased with low miles and clean carfax. Local car. Everything works like a dream and drives beautiful. All of the sudden it just shuts off ()Northstar engine() and I have to place it in park and start it again. It usually just happens on slow traffic. No engine service light so I can't get the auto shop to get me an error code. What it might be?

View 2 RepliesRecently my check engine light came on on my 98 Cadillac Deville. I went to Autozone and got a free engine diagnostic and was given a printout of a bunch of stuff I did not understand, the technician told me it was just an issue with the light, and it could be fixed with unhooking the black end of my battery for 10m. Just a little bit ago, i popped the hood, and touched the black end of the battery to see how i could unplug it. When i touched it I heard a click and now there is no power to my car. Every time i jiggle the negative end I hear a click from the right side of the engine and nothing happens. I did not even unhook the battery.

View 2 RepliesI have a 92 Deville. I drove a pretty good distance today and on the way home stopped at the store and left the car on in the parking lot. I got in and the engine died as I tried to pull out of the lot. When I try to start the car all the lights come on but nothing happens, no clicks or anything. Lights don't even go dim. Could this be the alternator? I know that the starter suddenly dying won't cut off the engine like that. Everything seemed fine before idk what gave out?
View 6 RepliesThe check coolant message comes on my message center on my 2002 Caddy Deville. I have checked this and there is plenty of coolant. Can this be repaired without removing and installing a new coolant overflow tank?
View 4 RepliesI have a 2003 Escalade that I have maintained since day 1. Occasionally when driving the car it will say system disability and reduced engine power, which drops the speed to 20 and I can give all the gas I want it will not go. Happening on and off for 5 months. I can shut it on and off a couple times and it will go back to normal. Have taken it in a couple times to dealer and they have drove it and drove it and it behaves. They believe it is the Throttle body and sensor. But for the price of it, just replace the fuel pump 2 weeks ago, they suggest to see it happening to give me a 100% diagnosis. For now they believe it is that. Should I fix it or wait till it happens and slowly putt into the dealership.
View 4 RepliesMy 2004 Cadillac CTS 3.6L started running rough, check engine light flashed on and off. Codes P0300 and P0303. The car has about 119000 miles. Could this just be the plugs? The car has been running fine up to today.
View 2 RepliesMy car started overheating and when I got under the hood I noticed that one of the belts was torn up pretty good. I'm guessing that this belt runs the fans or something. I am wondering what the name of this belt is and how hard it would be to replace?
The picture looks too small to be able to see it, but it's the belt on the right side of the engine block, next to the oil dipstick. The second picture loaded upside down.
1995 Cadillac DeVille 4.9 L Check engine soon light comes on, battery voltage high. When I increase speed the head lamps get brighter when I decrease speed the head lamps get dimmer. I changed the alternator because that's what a mechanic said I needed but I still have the problen battery voltage high. Will this damage the battery or other components? Should I stop driving the car.
View 5 RepliesI have a 2009 Prius with about 38k miles. Lately I have been observing that the mpg is constantly dropping and has reached 38 now. For the past couple of weeks, I started noticing a weird noise as if something was rubbing against something else. The noise would come and go, as if something was trying to engage. Upon further experimentation I noticed that it was related to A/C - when the noise would happen, if I raised the temp enough to turn off the A/C the noise would stop. After that if I dropped the temp back, the noise wouldn't come back.
Anyway, today all of a sudden I noticed the A/C was not blowing cold air, so I was sure the A/C went down. However after sometime the car gave me red bang, and it says Problem on the screen with car sign and exclamation, and a check engine light. But the car drives just fine.
I own a 2007 Suzuki Grand Vitara, V6, about 104,000 miles. My mechanic recommended the annual oil change in December 2015. My vehicle started making a loud tapping noise July 2016, so I took it to a mechanic. My mechanic discovered my car had no engine oil and there's no evidence of a leak. I have to replenish the engine oil every three weeks. My mechanic recommends I replace the PVC Valve; I'm unsure if the issue is the PVC Valve or oil compatibility issue. Oh I must also mention (not sure if it's related) when driving or parked and my a/c is running, the a/c intermittently blows out hot air....I can hear the transition like another vent suddenly opens up.
