Chrysler :: 1989 - Check Engine Light Came On - Running Roughly
Aug 7, 2013
Recently, my car has started to run rough with the check engine light on. I cycled the key 3 times and checked for codes. I got a code for the MAP sensor and a code for the 02 sensor. I got no codes for a misfire, so I guess the plugs and wires are okay. I bought a new MOPAR Map sensor and installed it. It still runs the same and the check engine light is still on.. My question is, is it necessary to disconnect the negative on the battery when doing this and for how long? I did disconnect it for about 2 minutes and it still was the same.

My '06 Pt Cruiser A/C works fine @ speed, but idling and @ stop lights it blows moist warmish air and idles roughly.

We have had an engine light that comes on when it is wet out. (Usually from rain) Until recently, the codes were not stored in memory. The last time we tried this, there was a 420 code set. Our mechanic said it was the catalytic converter. This vehicle is a 2006 and only has a 100,000 miles on it. Neither of the oxygen sensors have been replaced. The car doesn't seem to run any differently when the engine light comes on.

My mother in-law has a 94 Chrysler LHS, 3.5 V6, auto, 66k. Yesterday she was driving home and said the check engine light was on. I went to check it out and the light was not on. The light come on when the key is turned on but goes out when it is started. This is not an OBD-2 car it has a little blue plug and i do not have a code reader for it. Took it to auto zone and they do not have a code reader for this car. Auto Zone and Pep Boys both told me that if the light is off there will not be a code. Further checking on the internet I found out you can get a two digit code by turning the key on and off and count the flashing check engine light. It worked I got code 12 and 51. 51 means lean O2 sensor. If this is true that why does the CEL not stay on. How can I test the O2 sensors?

I drive a 2002 Chrysler Sebring convertible with about 130,000 miles on it.
I was driving down the highway in early November when the check engine light came on my car. I took it to Aamco who did some diagnosis and replaced a solenoid assembly in the transmission. The light went off and I was on my way. I never got the exact code.
About a month after that, the light came on again. This time, I got a low end code reader and scanned it myself. I got a "P0700" code, which I've read is a generic code that the transmission system sends to the computer or something. So I used my reader to erase it. However, the light came on 2 days later while I was driving down the highway at about 70 MPH.
So I went to an auto parts store to get a more detailed scan with a better tool. This one came up "P0740 Torque Converter Clutch Solenoid Circuit".
This feels weird, because the solenoid assembly was just replaced a month ago (and is still under warranty).
The car seems to drive okay. I don't notice any actual problems in shifting. The tachometer seemed to get up to about 3000 RPM on the highway. But I've seen practically new cars do that. The last time I had serious transmission problem it would rev up to about 5000 or 6000 RPM on the highway and still only getting up to about 40 MPH. That was 3 years ago and at the time I had a fairly expensive transmission repair (which included a new torque converter).
But like I said, the car seems to be driving okay. I don't drive much. Maybe 100 miles a week? And even that is mostly optional in town driving. I'm not looking to keep this car for more than another 20,000 to 25,000 miles though for the time being I cannot afford a new one.
What are the possible causes here? What are the consequences of ignoring this? Like I said, it's still driving fine and as the old saying goes "if it's not broke, don't fix it".

I have a 2003 Chrysler Town & Country and the check engine light is on. I brought the van to my mechanic and he told me there was a code that told him there was a misfire on cylinder #1. He started out with replacing the wire to cylinder #1, no change. He replaced the spark plug, no change. He installed a new fuel injector, no change. The van runs a little ruff at idle and when at a stop light.

2004 Chrysler Sebring Sedan, 4 cylinder dual-overhead cam. My check engine light came on this morning and the code came out as the catalytic converter. The car seems to be running fine, at least no recent changes. I'm debating replacing this vehicle soon, and I'm wondering if it's worth working on the catalytic converter. I recently replaced the cam shaft position sensor as well.

2007 Chrysler Town & Country with 74K. The check engine light comes on and the parts store diagnostic says P0404, a clogged EGR valve. On my model, replacing the EGR valve involves taking out the alternator, which involves removing the passenger wheel. That's beyond my skill set.
So, can I just replace the EGR tube and pour some Sea Foam motor treatment directly into the EGR? Would that hurt anything?

When I put the pedal down to the floor for a little fun my check engine light will start flashing. I'm not sure how many times or for how long but it worries me.. The check engine light has been on but the car does have 233,000 miles on it but new engine was put in 100,000 ago

My Chysler Town and Country started fine on a morning when it was 9 degrees. (no garage, so it was out in the weather.) I let it run for a couple of minutes so things would begin to thaw and then I drove to work. It ran really rough. I figured that once it warmed up, it would smooth out, but it did not. Even after the weather warmed up into the 50's 5 days later, it still runs rough. Now, I am also getting a check engine light. What could be wrong?

My mechanic tells me I need the intake manifold gasket replaced (check engine light on, engine surging, running very rough). How much damage can I do to the car by doing this repair myself and screwing it up? I've done lots of repairs on my car before -- brake pads, rotors, replace oil pan. I also have a copy of the manufacturer's shop manual.

Our R32 has 2428 miles- and today the check engine light came on and it started to run pretty rough, babied it home and the the light was blinking when I turned into the driveway.. I know that booklet 3.2 in the owners manual is diagnosing catalytic converter issues...I have always used super unleaded, it hasn't even reached the halfway point of the first service.

Filled tank with 8 gallons of 91 octane to top off. One hour later noticed car running rough at idle then check engine light comes on. Could it be the coil pack? Car has been running very well until now, and this Gremlin appears. I don't think it's the gas.

Went to the dealer because my idle was running both too low and/or too high, check engine light came on.
1) Replace air intake manifold because air flow flap is faulty.
2) Oil leak out of upper and lower timing belt covers - need to replace gaskets.
3) Missing!!! the high note horn

I recently replaced the head gaskets in my 2003 Malibu. First time and all seems other than it runs rough at stop lights. The check engine came back on and so I had it read and there is an air flow issue. Is there anywhere that I can get a schematic for the vacum lines? I have all over and cannot seem to find a loose or broken one.

My check engine light came on in my 06 toyota avalon. i had the code read at pepboys and they said it was something like 0300 misfire. i took it a few days later to my personal mechanic and he said nothing popped up when he tested the code. i notice the car (engine) is running a little rough though. What is the firing pattern as i want to try and fix by putting new plugs and coils.

I have a 2004 VW Touareg with 116K miles. Yesterday the check engine light came on and she is running very rough at low RPMs. The manual tells me that there is either a problem with the exahust manifold or an O2 sensor is bad. It feels as if she is struggling for air. When you start the vehicle the check engine light flashes then stays on in the cluster. What can I expect when I take it in to the dealership? Is there anything I can check before I take it in?

I have an 03 Passat with about 70K miles on it. My daughter put rug in it this morning (about 7 gallons) and since then the check engine light came on and the car is running really rough at stops. While accelerating, it seems to be fine. It is also getting about 10 mpg less than normal. MIL codes: P0300, P0301, P0302, P0303, P0304, and P0171. He said the P03xx codes were related to misfirings on each cylinder. The P0171 is a bank 1 failure (?). What do those codes really mean and could they be related to bad gas? Sent her off in my TDI JSW so she's not out on the highway if the Passat decides it doesn't want to go anymore.
