Oldsmobile - Alero :: 2003 - Entire Engine Shudders Upon Start And Check Engine Light Flashes

Having some issues with my 2003 Alero 4 cylinder. Upon start the entire engine shudders and the check engine light flashes. I have to turn it off and turn it on and it will stop most of the time. I've taken it in and the mechanics can't get it to reproduce the same issue for them. Just replaced all four plugs, boots, ignition coil.

Alero :: 2003 Security Light Stays On Preventing Engine To Start

For the past few months security light of my 2003 Alero keeps on activating preventing the engine to start or it doesn't even crank.

I always do the reset technique..."Turn ON the engine key for about 20 minutes and wait till the flashing security light become solid before starting the engine." Today when I started the car the security light comes ON and stays on for my whole 50 Kilometers travel. When I reached my destination,I tried to turn ON and OFF the engine waiting for my luck to have the solid security light to come OFF,but no luck.

Will this problem have any effect on the performance of the car? Will the car stall while I'm on the road?

Ford F-150 - 1997-2003 :: OD Off Light On The Shift Selector Blink / Service Engine Soon Light Comes On

I have a 1999 F-150 w/ 4.2 V6. and auto trans, truck has 219,000 miles on chassis but only 25,000 on engine and 10,000 on trans. I've been getting obd codes p0705 and p0715. I replaced the position sensor on outside of trans. but I continue to get the codes off and on again. I noticed that the O/D "OFF" light on the shift selector blinks simultaneously when the "service engine soon" light comes on. I've noticed that there is no low gear unless I have it in D from a dead stop, and not even when downshifting manually.

Ford F-150 - 1997-2003 :: Service Engine Light Comes On

2001 F150, 5.4L gas, 4wd, stock, 217k miles, auto trans. Bought it used about 4 years back.

Currently away from home base. Left Saturday for a 600+ mile trip. All fluid levels are good. Truck has been reliable. No major issues other than an alarm malfunction a while back which got sorted.

About 90 miles into the trip down the highway, the service engine light comes on. Hmm. At the next fuel stop I tanked up. Started and it was a bit rough the first few seconds and then settled. Seemed to have an engine noise I had not heard before.

Pulled over in the station and popped the hood. Oil good. Coolant fine. Power steering fine. Listening to it I could definitely hear an unusual sort of "ghost" like sound. Hard to describe. Sort of like a low "woooooo." It was low, but definitely there and not normal. Could be unrelated to the engine light. Pulling out of the station the sound varied and got louder with slight acceleration. Possibly beginning of an accessory bearing meltdown?

No acceleration or dying issues. Got back on the highway and kept on trucking for 600+ miles. No running issues. No shifting issues. Ghost noise not noticed at highway speeds.

The power steering pump is probably in need of replacement at this point with this mileage. It does drip slightly, but not a lot. It may be the original pump for all I know. Same with the water pump.

The alternator was replaced last year with a Bosch unit. I have never replaced the O2 sensors. Stock exhaust. Spark plugs were replaced a while back with Motorcraft platinums.

It is now Sunday night and I went out to listen for the sound, and it is not there anymore, but the service engine light is still on. First things to check with a truck that has 217k miles on it?

Was tempted to bring it to the dealer here, but it seems to be running ok in spite of the light coming on. So I may leave it until I get back home and check it more myself then. Can't do much here since I don't have my tools/service manuals etc with me.

Nissan - Sentra :: 2003 - Service Engine Light Came On / Code P0302

I recently had my "Service Engine Light" come on, Sunday to be exact. I went through my normal procedure of checking the fuel cap and drove several times to no avail. So today I ran by Autozone where I got the P0302 code. Now I realize I could go in for a tune up, but I'm a college student and just spent all my money on books so I'm looking for some DIY solutions before I lay down any large amounts of money. Where to start. As for a bit more background, I filled my car up with gas on Friday, the light came on Sunday and the car will shake on initial idle of the car.

Cadillac - Deville :: 2003 - Service Engine Soon Light / Sluggish Acceleration

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.

Pontiac - Grandam :: 2003 - Service Engine Light Came On And Began To Blink

My wife has a 2003 Pontiac Grand am GT 3.4L V6. A few days ago my wife was out and tried to start the car and the service engine light came on and began to blink. (Prior to this the car was running well with no service engine light) The car was running very rough at this point so we shut the car off and I pulled the codes at witch four codes came up witch were: P0205, p0206, p0300, p0443. So I had the car towed to the shop and they said that they thought that it was the oxygen sensor but after that had been replaced they had concluded that the oxygen sensor was not the problem so they had placed the old one back in. Then they said that they restarted the car and it was running fine but then pulled it out of the shop and began to run rough again.

At this point they were thinking that there was a short so they checked the wiring from the ecm (?) back to the oxygen sensor and could not find any problems. And needless to say they started the car and it began to run fine again so they told me to come and pick it up and drive it for the weekend just to see if it was a lose connection that was possibly there. So needless to say once I picked it up the service engine light was still on but the engine sounded good so I figured I would drive the car home and maybe the light would shut off. Well upon taking off and getting a few miles down the road the engine started to idol at 2000 rmp when in park or neutral.

So I stopped and pulled the code and got P0443 again so while I had the scan tool connected I cleared the codes to see if the light would come back on with the same code or with multiple again. The service engine light stayed off. So the high idol continued for a few miles I also did try to restart the car and the problem did persist. About 5 more miles down the road the car started to overheat and the reservoir had overheated. So at this point the engine sounds good it is not running rough but is really high idol. The check engine light did not come on since I cleared the codes in that short drive but I do not want to drive it because of the overheating. I do know that the coolant level was good when we started the car.

Pontiac - Grandam :: 2003 - Turns Over But Won't Start / Service Engine Soon Light Is On

My car won't start and I'm trying to figure out why. What is going on. The kind of car I have:

2003 Pontiac Grand Am
2.2L, In-Line4, VIN(F) DOHC
Has about 160,000 on it

Issue I'm having:

Car turns but won't start
"Service Engine Soon" light is on
Tried to jump it (made sure to let it charge for awhile) to no avail
Was low on gas but was not empty -- we filled it up and it still won't turn
Specifically for this model, it is not the Security Bypass issue (where you reset it after 10 minutes)

Recent work history:

On 2/4/14, I took my car to the shop after the check engine light was blinking when I tried to go above 25mph:

Replaced Spark Plugs
Replaced Air Filter
Replaced Ignition Coil Pack
Replaced Spark Plug Boot (Coil to Plug)
Replaced Ignition Control Module
Replaced Fuel Filter

When I drove my car away, the "Check Engine Light" came on. Took it back, this is what they did:

Access computer for codes : "P0172 system to rich on bank 1"

They told me that there was a possible injector leaking down and recommended a fuel injector cleaning. They said I was ok to drive it for awhile and did not have to do it right that moment.

I did light driving on the car but left it in the burbs as I live in the city. When I moved five months later, I brought the car back to the city. I noticed my air conditioning was not working (will blow heat just fine but will not blow cold).

I changed my oil not long after bringing it to the city, in that same month. Besides the air conditioning, I haven't had any real issues and have done local driving through the city.

I took the car out on Friday, drove to Madison, and drove back the next day with no issues (300m trip). This morning we took the car out to the burbs to visit family (20m) -- now it won't start. What it could be?

Ford F-150 - 1997-2003 :: Engine Service Light - Codes P0171 And P0174

2001 F150 5.4L Triton Motor. Everything seemed o.k. then got the Engine Service Light. Checked with reader and above codes only appeared. Read numerous articles/videos and pulled the PCV hose/boot assembly and replaced the whole thing with oem part. Visually checked for disconnected tubing = none found. After this and with the new hose assembly in place I performed a reset. With the scanner still connected restarted engine and read values: ST FTRM1&2 = -.08~+2.3, both oxygen sensor voltages are varying and the LT FTRM1&2 hang around +26 and +28.

From what I understand the ST seems o.k. but the long term is WAY OUT OF WHACK. Started it up again and took carb cleaner spray and covered all the connections I could see = no change in engine rpm. No cracks in the air cleaner body. Big plug to the MAF was inserted and plugging the hole. I am thinking of making a smoke "machine" and trying that or removing the hoses from the throttle body and plugging the holes in the throttle body and see if that clears them up. IF it does then connect one by one and keep checking the values. Lot more work but I am at a loss.

Ford 7.3L Power Stroke (1999-2003) :: Service Engine Light At Acceleration Only

So i replaced the faulty injector and the truck starts up great and runs great. The only issue is that now when i accelerate, the SES light comes on until i let it up a little. If i am at cruising speed or just a steady speed the light goes off. I havent checked for codes yet because the light didnt stay on. I have AE and know how to use most of it. Is there something i should be looking at? Could it have something to do with the Blue/Gray CPS i installed or maybe there could still be an air bubble in the oil rail from when i drained the rail ? I have a DP tuner and stage-1 injectors. Regardless it sure is nice to have my truck back out on the road. It was a horrible 3 weeks without it.

Ford F-150 - 1997-2003 :: Service Engine Light Came On - EGR Replacement Code P0402

Last week my service engine light came on. Friend checked it with his code reader. Got a P0402 code insufficient flow EGR valve. I have read several different threads on this subject on another Ford truck forum, slightly confusing me. Should I trust the code and just replace the EGR valve or do a number of other things that

1. Clean the throttle body first?
2. Test the EGR valve by blanking it off?
3. Test the DPFE valve?
4. Replace the DPFE valve instead of the ERG valve since the EGR valve rarely goes bad?
5. Only get OEM parts since after market parts do not last?

Ford 7.3L Power Stroke (1999-2003) :: Service Engine Soon Light - No Codes In Torque

The SES light in my 2001 7.3 came on about a month ago while I was towing a light trailer in the SoCal mountains. When I got home I spent about 2 weeks replacing the injector o-rings and glow plugs. I discovered while I was in there that the head bolts on the driver's side where loose. I retorqued them to spec.

Both batteries were disconnected for the 2 weeks. When I started the truck the SES light was still on.

My Torque Pro app isn't showing any error codes, and is reading live data correctly. (I didn't have the app when the light first came on; I only purchased it after I finished the repairs). Am I missing something? Is the SES light not necessarily connected to fault codes? If so, wouldn't it reset after 2 weeks with the batteries disconnected?
