I just got my first dub, and it is a project car. I have had it serviced and it still idles rough when in drive with foot on the brake but idles normal when in park. a
View 2 RepliesMy 09 corolla is running rough when idling in drive. It doesn't happen in park or neutral.
View 5 RepliesHad the oil changed yesterday and changed the air filter myself. Car is now running rough, surging, when in drive and stopped. Runs cleanly when moving and surge is significantly less in park and neutral.
View 3 RepliesI bought a 99 7.3 been in the trees for a few years pulled it home and now trying to get it running. Did a service new filters and oil fuel too. I can get it to start and will run but runs very rough and if you put it in drive cant pull its own self. I don't have a check eng light on. And found out my scanner is a pos lol. it will hooked up and then try to pull codes and loses it connection. But that's the scanner will not work on my other 7.3 as well.
I am making high pressure oil checked off the rail with gauge and it will build up to 2000 psi when I rev it. but missing like crazy. I swaped the pcm and idm out of my running 7.3 and it didn't change a thing. I have checked the pass though and they are fine. pulled drivers side valve cover off and no oil leaks when running and rockers are fine. new ipr valve as well too. I know I need to get a scanner to talk to this thing better.
2002 F250 7.3L suddenly idling and running very rough, and doesn't have any power. Truck has been running perfect, it's my daily driver, and just put a couple hundred miles on it yesterday with no problems. I had been having some transmission issues when I tow heavy so I bought a new transmission yesterday. This morning I pulled the truck into my garage to change the transmission. Again truck ran fine, no signs of any issues before the trans swap. I changed out the transmission, which included unhooking the trans wiring harness from all the various sensors, and unbolting the starter.
I didn't mess with anything in the engine bay except for unhooking the batteries. I had also repaired the overdrive button wires, as they had been pinched in the steering column and the button wasn't working. When I got everything hooked back up I cranked it up to get the trans fluid flowing through the transmission, it started right up and idled good. I had it running for a few minutes and it was beginning to make a little more noise than usual. When I started to back out of the garage it was getting pretty rough, almost like it was running out of diesel. I put it in neutral and gave it some throttle and noticed I was getting white smoke out of the exhaust and could smell diesel pretty strong.
I checked my injector resistance at the valve covers and got around 4 ohms +/- on all of the injectors. I rechecked all of the clips and harness that I had messed with. I took a look at the ICP sensor and it has oil in the connector which I know can cause a rough running condition in some cases. It looks like it has had oil on it for a while. I unhooked the batteries again for about 20 minutes to try and reset anything that may have messed up. I checked a bunch of connections under the hood to see if anything was unhooked or loose.
I also cleaned up the connector on the ICP sensor. I started the truck back up and it idled perfect so I pulled it back out of the garage and headed down the driveway. It almost immediately started running rough again and barely had the power to go up a small hill. I pulled back in and tried unplugging the ICP while it was running, which made a slight difference in the idle but still very rough. I plugged it back in and the idle progressively got worse until it was chugging really bad. I shut it off after that and haven't messed with it again.
What might have happened? Could it be a bad sensor or transmission position sensor in the new trans? Is it just coincidence that this happened with a transmission swap? I am going to get a new ICP, but if there is anything else I can try/check before I can pick up the ICP on Monday let me know.
As winter comes in full force to NYC I've been experiencing some rough idle on my is350 AWD even after warming up my car for about 3-5 min. For ex. when I am at a stop light and have my foot depressed on the brake it feels as if the engine is revving higher than usual as if the acceleration pedal is lightly being depressed while I am braking. Is it just due to the cold weather?
View 11 RepliesWell all is ok now but I am not one to ignore or forget a symptom. After a long drive into the city over Christmas I pulled in to park at my destination. It was idling rough when I stopped. Vibration my be a better adjective but not too bad. It did not feel like ignition etc, not MIL on and putting it in Part did not change it. I shut it off and went inside for the festivities. Started it for the drive back and all was ok.
Whether some bad gas with water got in or something else I don't know as it as above freezing but I got thinking about this dam harmonic balancer pulley may have had on the 3.3L go. I have seen some post in in 2006 as well with this engine in other models. I got some 47L of quality Shell gas later on as well for the drive home days later. Still no issues but... IT HAPPENED AND I DON'T FORGET so I am thinking about it.
Is this a major problem on SF's some went as early as 30k from the owers. I had no other indicators and I doubt there is going to be much to see in the space with a light.
2004 Santa Fe 3.5 has started idling rough when in park or when stopped and in drive. When I'm actually driving, it runs smooth and doesn't seem to have any issues or hesitation. I tested my EGR valve with a vacuum pump and it held 7Hg of vacuum and did not leak. I think that indicates it is working still?
I think my issue may be the EGR Solenoid, but I'm not sure how to test it. When I remove the Green hose from the Throttle Body, there is a good vacuum coming from it and my car speeds the idle up and seems to run smoother. I think that means there's some kind of blockage? When I have the Solenoid off, you can blow through it, which I think means it is open.
I think I have to replace the Solenoid, but didn't want to just buy parts.
I am about to begin servicing my new/old jeep. I am unfamiliar with fuel inj.
it is beginning to run a bit rough idling in drive with brake applied. It is beginning to start less easily, turning over longer before firing...
ok,up to yesterday, my wife's car started and ran fine. but we had not driven it in about 3weeks, and it was on empty. well, my kids would listen to the radio and, i think, starting it while we were at work. anyway, they ran it out of gas. so put gas in it, 3gallons, turned the key on and off a couple of times to get a good prime. started it up, died, i figured not enough fuel, yet tried again. started, but started spitting and sputtering and idling really ruff, had to hold to the floor to keep it running. removed the maf. it started and did the same. finally, i held down the gas and brake at the same time, took off to the store, got gas, but it died half way there. got it to the pump, put more gas thinking that's the problem. nope, the same. got it home, but when i let off the gas, it idles like it's not getting fuel and dies. so, any clue what it is? remember, 3 weeks ago it ran fine.
View 1 RepliesI have a 2010 Equinox with about 52000 miles on it. At about 48,000 I took it in for the 50G maintenance. The car ran with a fluttery sound that I did not really notice until it was brought to my attention. Recently the car began running rough and stalling when idling. there were no warning or indicator lights lit. I had OnStar run a remote diagnostic and they said there were no codes. The day after the diagnostic the check engine light went on , while at the same tie the rough idle and stalling went away.
I brought the car in for service at the dealer. They said that the car had several codes indicating low oil and the car was down 2 quarts but there was no leak. They also said the noise I heard was the timing belt. The noise is gone after the service and the car is running smoothly. Coincidentally, or not, I got a notice from GM saying they were changing the oil monitoring software on the 2010 Equinox to recommend me frequent oil changes.
1) What could cause the car to loose 2 quarts of oil over less than 6000 mile? Is this normal or an Equinox problem.
2) Would low oil cause the timing belt to make a noise.
3) Do I have a lemon and am I being ripped off y the dealer?
Owning a Hyundai. I have a problem and it seems to be pretty common but haven't gotten anywhere with it yet. Last week my 2004 accent 1.6 manual transmission started running rough. It was idling higher than normal and while driving would not go past a certain rpm (about 2500 if I had to guess,no tach). On the way home from work it was running this way and then started badly misfiring and shut off, when attempted to restart it would not. I pulled the codes with a scanner and got p2400, p0562, and p0121. I charged the battery and replaced the throttle position sensor, still won't start. I can hear the fuel pump kicking on when I turn on the ignition. Also found the ecu 1 fuse blown, replaced it and continued to attempt to start with no luck, fuse was blown again. Like I said I haven't owned the car long and I don't know much about it. I am not sure where to go from here and I don't know how all these symptoms are tied together.
View 42 RepliesThis problem has been getting worse over the last 2 years. When the car starts it idles fine at about 1000 RPM. As soon as it warms up, it starts to idle rough, between 500 and 750 RPM. It almost quits running. As soon as you give the car some gas it runs just fine. About 3 weeks ago I got a "Engine Lean" check engine light error. I reset the system and have not gotten the error again. Since then I have: changed the MAF cleaned the EGR (made sure it closes completely and ohm out the coils in the actuator) changed the O2 meter on the exhaust manifold cleaned out the throttle body Ohmed out the air idle controller. What I should check next. I was planning to check the fuel pressure in case it is a fuel system problem. It is a 1999 ....
View 5 RepliesMy daughter returned from college with her 2000 f150 4.2 idling and running rough on acceleration. It is throwing a P0171 code only. I replaced the isolator bolts/plenum gaskets four years ago because of a P0171 & P0174 codes.
So far I have replaced the MAF, new PCV valve and elbow, checked all obvious lines for vacuum leaks (though I suspect a leak somewhere still). Also, a quick check of the plugs show some lean color/deposits on the drivers side only. Any thoughts or troubleshooting I should try next?
I replaced the heater core in my truck this weekend. The only thing I was worried about was pulling the dash. The truck is a 1998 f150 with the 5.4.. Everything went fairy well and decided to replace the AT Shift cable as well. Got everything put back. Truck runs, no leaks, no antifreeze smell. After running about 20 minutes, it started idling a little rough and my check engine light came on.
The codes are p0136, p0156, p1131, and p1151. I know these are related to the OS sensors. My question is could it be as simple as I miss an electrical connection when putting the dash back in? Was thinking possibly somewhere on the passenger side under the kick plate or possibly something while hooking up the heater hoses? Maybe even a ground that didn't get connected back when putting the das back in?
I've got a merc C230 Kompressor that has 174k miles on it. The car typically runs really well and is not underpowered or anything. Last weekend I took a road trip that was 400 miles or so. The car did fine for the first 300 miles but then began running rough and was underpowered. Was acting like there was a fouled plug. I pulled over and stopped the car where it sat for about 5 mins. When I restarted the car, it was back to normal, with a smooth idle and not underpowered. It ran fine for about 30 mins and then began running rough and underpowered. I find that when it starts running rough, if I stop the car and turn it all the way off for at least 60 seconds, then when i turn it back on it will operate normally again for a bit. This also only seems to be happening when its really hot weather, 90 degrees F or higher.
View 5 RepliesJust noticed the other day the Passat was idling significantly rougher than usual, most of the time it's smooth as butter but not so much lately. It's not rough like a bad misfire, just not very smooth anymore. This could be indicative of the dreaded oil-pump bolt failure rearing it's ugly head (finally)?
View 1 RepliesI have a 1997 ford f150 5.4 litre truck and the truck runs real rough kinda surging in park and in drive and reverse i have a couple oxygen sensor codes P 0171, P0174, P0136, P1131, P1151 and an idle air control valve code P1506...
View 5 RepliesI have an 08 Passat 2.0T with 44k on it, just did the 40k service around 42k. This past Friday I filled up from almost completely empty, and later that day and ever since the engine has been idling rough and the CEL came on. Gas cap has been checked already.
Should I wait to go to the Stealership until I've burned this tank of gas out? Is there anything else I can do that you can think of?
I haven't started my passat for the winter and I finally did today. It was ruff start/idling and I pretty sure it was misfiring on one of the cylinders. I turned off the car and start it again...same thing, ruff idling like 3 cylinders were running. I waited five 5 mins and started it again, then it was a normal start on all cylinders. But the engine light came on, even though it started properly. I know I have to clear the code to get rid of the engine light. But I want to avoid any future misfiring. So I'm thinking new spark plug/coil overs.
View 9 RepliesOnly thing I've noticed is the idling is a little rough but the car has 88k on it so that's expected. I haven't checked the cam follower yet and know I'll probably need to change it so that's going to happen in the next week.
I had a code for P000A & P2293 for a few months that would throw a MIL and I would reset it and it would come back after a while. I finally replaced the cam sensor and I didn't see a MIlL for about 6 weeks and one day it came back. Once I scanned the car it showed P000A again. I cleared the code and everything seemed fine until yesterday. I went to start the car and the car wouldn't turn over.
I pulled the key out and tried it again and it worked. More and more I think about it, the car doesn't turn over smoothly over the past few months but maybe I'm just looking for things. I ended up scanning it last night and it had a code for P2293 & P0011. I cleared them both but what could be causing all this and cannot afford to bring the car in to the mechanic. It's out of warranty and I'm broke and X-Mas is around the corner.
