Ford - Explorer :: Vehicle Starts And Idles A Bit Rough - Cylinder 8 Misfire
I just got a 4.6 4WD Explorer in for rough running. It had timing chain noise and some odd codes for primary coil H codes along with cylinder 8 misfire.
I replaced the coil to get rid of the "H" code and it was fine. Still misfires on 8, and I really don't care because it's coincidence that the timing could be affecting it or perhaps.... bent valves!
The vehicle starts and idles a bit rough. Can't go very fast, and of course I know I should run it as little as possible!
Here is the deal, how should I present this to the customer? Should I let him know that some valves could be bent after replacing the chain (and all associated parts) and that it could still be effed? Or will I be fine after replacing? Pretty much, where they had a tensioner failure/guide breakage and valves bent too?
Accent MC (2006-11) :: CEL Flashing / Rough Idle - Cylinder 1 Misfire
I did not get the specific cel code but its what the guy told me at autozone.
Long story short. Washed engine, let sit for about 30 mins. Car started with flashing CEL and was "puttering" and very rough idle. Drove home took intake off and replace with stock, took spark plugs out and they were not wet. Then let it sit for about 15 mins. Started just fine. No CEL at all.
The accent saved the CEL and the guy told me that Cylinder 1 had a misfire.
My question is, should I do anything now even though the car seems to be running ok?
Ford Ranger / B-Series :: 2003 - Misfire And Rough Running / Flashing CEL
2003 Ranger FX4 Flareside
4.0
Automatic
145,000 Miles
Here's my issue: My Ranger has been running like a dream until yesterday.
I took off on a parts run for my sons Ranger. I got to a stop sign and as I stopped, it started missing and barely running. I nursed it back home and checked the flashing CEL. It was giving me a misfire on #3.
Since I had been planning on changing the plugs and wires, I dove in and got it done hoping that was the cause of the misfire.
Started it up, same thing. I went to the next obvious item: coil. Replace it, still running like crap. Gave up for the night.
Today, I thought I would dig in using the tips here on the forum. Did the spray down...no errant spark anywhere. Tested fuel pressure: 65psi no drop in pressure on acceleration.
Started pulling wires off the coil one by one. Four of the wires resulted in running worse. 2 had no effect. #3 and #6. The coil was producing plenty of spark on all 6 ports.
At this point I was sure it had to be 2 bad injectors. Since I couldn't get injectors tonight, I moved them around after cleaning them a bit and tried my wire test again. The problem stayed on the back 2 cylinders!?!
I tested for voltage on the back injector plugs and I am getting voltage. I also used a stethoscope to listen to all of the injectors. The back 2 seem to remain silent. I have also unhooked the battery for 20 minutes to reset the PCM. Still missing and running rough....
Here's a list of what I have done:
Autolite Double Platinum APP5144 plugs. .062 gap
Autolite Pro Series wires #97051
BDW E97P Coil
New air filter
What should I do next? I really don't know where to go next.......
Camry :: 2004 - CEL Code For Upstream O2 Sensor / Idles Very Rough
I just bought an 04 camry 4 cylinder. It was running perfect when I got it but the moment we got home it threw a CEL. The code was for an upstream o2 sensor, however I did a resistance test and the heater circuit is fine. I did a voltage test on the blue and white wires and I got 3.3v and 2.9v. I don't remember which wire gave me which voltage at the moment. I would like to know if this data is a good thing or if it's broken. I do not have any data to go off of, and I couldn't find the factory service manual online. Its also worth mentioning that it idles very rough and the catalytic converter is giving a rotten egg smell but not all the time. When neither of these things happen the CEL goes away. I do not want to start throwing parts at it.

After sitting engine cranks longer than it usually did before it starts. idles a little rough. engine light comes on after it been running about 30 sec for 1 min. after that seems to run fine.check codes po446 and p1633 always come up. if you let sit a bit with key on starts right up.replaced gas cap checked evap lines, and changed filter no luck. Did notice with lines off evap solenoid key off or on i can blow through it. that doesn't sound right.
Checked fuel pressure. key on jumps to 90psi then falls to 55psi and stays. turn off key and leaked off 10psi in 5 min.start engine while watching gauge does the same as when the key on except it falls to 30 to 35 psi and bounces between them. i think this is way low. What is the correct pressure? Shut off engine and drops to 20 in 5 min. Next I plugged line on test tee going to fuel rail and tested same results as key on. the convinced fuel pump was bad since regulator and check is there. replaced pump. problem still there.
Santa Fe (CM - 2007-12) :: 2008 2.7l Misfire / Flashing CEL
2008 GLS AWD, 2.7L w/ 66500mi. This happened on my way home from work this AM. Vehicle cold started normally, but I noticed a stumble as I idled out of my parking spot after a 12hr shift. All gauge indications looked OK. A few hundred yards down the road (and deep in the hood no less) I can feel an intermittent vibration/stumble and now I get the *FLASHING* (misfire) check engine light.
5am Sat morning and I'm already on the highway for my ~35mi ride home. The vehicle behaved OK, but you could feel a definite power loss, indicative of not firing on all 6. I hated to, but I had to drive it the whole ~35miles with the flashing CEL. I couldn't smell rich exhaust, nor did I notice any black smoke, etc.
Now I'm SOL. I have no warranty since I'm a subsequent owner (3rd owner of vehicle). Of course I lent out my generic code reader 2yrs ago and never got it back. My garage is currently upside down, tools packed away..etc. We just had a baby a few weeks ago and moved to a new house. Perfect timing.
Ford F-150 (2004-2008) :: 2007 5.4L V8 Idles Very Rough / Shaking When Stopped
I have an 07 f150 v8 5.4 and it idles very rough. When i start it it seems to start really rough and just about everytime im stopped its shaking just enough to annoy me. Do you think its the spark plugs? I took into the dealer about a month ago and they said everything was fine. But its still doing the same thing. Also the A/C tottaly sucks is that they way it is? When I accelerate the cold air gets kinda warm and it doesn't get cold until i get up to speed.

I have really taken care of this 2011 SF Limited with the 3.5 V6 but it has always seemed to idle rough at a red light/stop sign while in drive. Is this common for all the 3.5 V6 engines? I run a fuel cleaner through it before every syn oil change and also use top tier gas. It drives nice but like I said, at a stop in drive it seems to run rough at around 500-550 rpm's.

Golf IV R32 :: Won't Start - All Dash Lights Are Flashing
My R ran just fine two days ago. I went out to start it this morning and I get all crank. No turn over not even a pop. Now, it is 3 degrees outside right now. I've started my car many times in the cold with no issue. Weird thing is all of the lights on the gauge cluster all flash at the same time. I have a code for a secondary o2 but that obviously is not the case. And yes the fuel pump did prime when I opened the door.

View 2 RepliesChevrolet - Suburban :: 2007 - Misfire After Working On Engine / SES Light Flashing While Driving
I replaced the oil pressure switch on an '07 Suburban 5.3L because the oil pressure was showing low once the engine warmed up. That did nothing, then I found out about that little filter/screen under the sensor. I intended to remove and clean the filter then reinstall it. While I was pulling it out, I dropped it back behind the engine and couldn't find it. I checked online and found a few people in other forums that said to just remove the screen as a "fix", so I left it out and put the sensor back in, just to get the vehicle drivable. It started right up and ran fine for me, parked it, and a after sitting for a few hours it started popping while driving with the SES light flashing on the drive home.
Code P0300 was set, no cylinder specific misfire codes were present. I checked the misfire data and cylinder #6 showed tens of thousands of misfires, #5 showed several hundred, but I think it was just picking them up from #6 since #5 is right after #6 in the firing order. I disabled each injector with a scan tool, all changed the idle except #6, it did absolutely nothing. #6 fuel injector had good pulse to it, I connected a fuel pressure gauge and put power/ground to injectors #6 and #4, both dropped the same fuel pressure. I did the "cylinder deactivation" test on the scan tool for the four cylinders that have it, they all did the exact same thing - the engine bogged way down for a couple seconds and then died. Is that normal? I can't say I've ever seen a V8 engine die before when running on 6 or 7 cylinders. I checked compression on cylinder #6, it showed very low, almost zero, but I tried it a few times and it would show just a little compression at times... valves staying shut? I'm thinking when I opened the pressure relief valve on the gauge and the piston was near the bottom of the cylinder may be when it showed some compression. I also switched the coil/wire/plug from #6 to other cylinders and the miss did not follow.
Could having that screen out cause this problem? Having the engine die when deactivating the cylinders makes me wonder if maybe it's commanding all four at the same time, although the test shows each cylinder being controlled separately. Using a MODIS, not a TechII. I just got done putting in a new filter/screen to see if it would make any difference, and of course it didn't.
Rodeo :: Intermittent Starting - All Lights On Dash Are On And Engine Light Flashing
I have Holden Rodeo, am assuming these are very similar cars if not the same. Our 2004 Rodeo is having intermittent trouble starting, sometimes when the key is turned it is dead, no clicking noise, all lights on dash are on and engine light flashing. it goes from being dead to a short turning of engine, eventually it will turn over but may have trouble firing. the next time it will start perfectly.
View 10 RepliesSubaru - Legacy :: 2011 - All Lights Flashing On Dash / Cruise Would Not Engage
Last week, the brake, traction control, cruise, and check engine lights all came on my dash. All but check engine were flashing. The car seemed to be driving fine but cruise would not engage. I drove it to a local mechanic who checked the battery and alternator and reset the computer. He said there was nothing wrong with the car. The next day the lights started flashing again so I made an appt to take it to another garage. This place said my gas cap needed to be replaced (hence the check engine light) and that my vehicle dynamic module was busted. My dilemma is that since picking the car up 4 days ago, and driving roughly 200 miles since, the lights haven't come back on. My current plan is to wait a bit and see if they do but I'm wondering if there's a chance that the VDM is ok.

2004 with 214000 miles. Brake pedal goes to the floor, red dash lights are flashing, I just added a container of brake fluid and still no pressure at the pedal. I'm guessing master cylinder.
My question is: Even though my brake pedal goes directly to the floor, how am I getting the car to stop at the very end of the push? Do the brakes somehow work as a fail-safe even the the hydrolics are basically toast? I know that's a long shot, but it wouldn't be the first time I've been shocked over systems in this car.
Ford Escape / Hybrid :: 2002 - Drive Lights On Dash Flashing But Seems To Run Ok?
This 2002 ford escape 3.0 xlt 4x4. on the dash you have your transmission #s laid out . the #1 seems to always be highlighted in a square. but as you move the shifter to whatever gear you want there is another square that highlights the selected gear. Also, before when you would have it in D it would flash back and forth from D to 2 just the lights not the transmission.

April 2009, I bought a 2009 Toyota Venza which I totally love. About 2 weeks into ownership the battery went dead. I had it jump startd and all was well. In the time since I bought it, the battery has gone dead 5 times. Numerous trips to dealer and can't find anything. The final straw was when I was having car washed and the battery went dead. I had to call tow truck to drag me out of car wash an take car to dealer. This time they saidit was a bad battery. Now my dashlights are flashing dim to real bright and my TRAC light comes on so I can't put car into gear.
