Buick - Lacrosse :: Oil Pressure Low Light Came On - Random / Multiple Cylinder Misfire Detected
2008 Buick Lacrosse CXL .. My son said the Oil pressure low light came on when he tried to start the car. It didn't want to start.
When I got there two hours later, it started but had a check engine light. But no low oil pressure light. Sounded like it was missing.
Code from computer came back P0300 "Random/Multiple Cylinder Misfire Detected". I cleared the code. Revved the engine to about 2000 RPM's and the CEL came back on.
Same code. When idling it feels like it's missing. The plugs look good, I am going to replace the ICM.

View 2 RepliesAccent MC (2006-11) :: 2007 GLS - Random / Multiple Misfire And Code P0300
I have a 2007 Hyundai Accent GLS. I just got it from a used car dealership (local) and it runs perfectly. It had a misfire code when i first got it, for all cylinders plus the p0300. It went away when i started the engine again, and didnt come back til a month later (Now). now it wont go away.
I went to advance auto and had them use their OBD2 reader for a trouble code and i got p0300, p0301, p0303, p0304. No other codes present.
I am not feeling anything bad, and from what I am told, a misfire feels like a hard shift. This is of course after getting the plugs and wires changes as well as an oil change. Standard preventative maintenance.
The mechanic used OEM parts got from local parts shop. i think the OEM plugs are the copper ones. I would have preferred iridium as they arent that much more expensive but I don't want to pay for another plug change.
The only symptoms I can think of, is that according to google, I should get around 380 miles to a full tank (11.9 capacity, 32 mpg city). I am only getting 280 from full tank to gas light.
I have also gone through a lot of oil. I checked the dipstick and it was below the low line, so i bought a quart of high mileage oil (same exact brand and type of oil that i gave to the mechanic to use) and it went to just above the full line. This was at around 1500 miles after oil change.
After visiting multiple sites about misfires, i found a few things that caught my attention. One is a site called auto service professional, which talks about the OCV for the MC accent. A lot of sites also recommend gaping the plugs at .035.

Accent MC (2006-11) :: Multiple Cylinder Misfire
My car has been really acting up lately (AGAIN) so I took it in to have it looked at and they came back and told me it had multiple cylinder misfire, and they wanted like $1200 to fix it. What in the world does that mean and what is entailed in fixing it? They mentioned doing a full maintenance on it.

I left the key on and drained my auxiliary battery(It was weak before) and when I jumped it it started and then shut off after ~20 seconds. I tried various different things and all I succeeded in doing was draining my HV battery from starting it so many times. So I disassembled the pack and recharged it and now it starts and runs but it is misfiring. It throwing 4 codes:
P0300: Random/Multiple Cylinder Misfire Detected
P0302: Cylinder 2 Misfire Detected
P0304: Cylinder 4 Misfire Detected
P1305: Ignition Coil 2 Primary Feedback Circuit
I inspected the igniters and plugs and they seem to be OK and I'm not sure where to look next. I'm not sure if the battery issue is related or not but I did replace the auxiliary battery.
Accent MC (2006-11) :: 2008 - Multiple Cylinder Misfire Codes
We bought the car used for my youngest daughter and it had a couple of codes in it. 1st was the o2 sensor.. easy fix, grabbed an OEM one and stuck it in. Then there was the Cyl 2/ multiple cyl misfire codes that kept getting thrown.
I've seen a bunch of post about people pretty much doing the same things I started out with and still having a problem.....
1) Swapped around all the coils.. still got a #2 misfire... So, coils are good.
2) Swapped in NGK Platinum plugs with a .032 gap.... still getting misfire.
3) Replaced the crank shaft position sensor...... still misfire
4) Noticed that there was an Ebay injector in the #2 cyl...... when I pulled the plugs, that cyl was running a little lean..... bought an OEM injector to go back in there...... still getting misfire
SO, I tried using a propane torch head and putting out gas around the intake to search for vacuum leak and got no response....... so, for the heck of it, I went old school and grabbed a can of starting fluid and started spraying it on the intake around where it bolts to head... bam... found a vacuum leak on #2 cyl....... ordered an intake gasket off of ebay, spent about 3 hours on it pulling the intake and replacing the gasket,( the bolts had loosened up over time and there were small tears in the gasket allowing it to suck air) .. put the new gasket on, cleared the codes and it's been running perfect ever since.
Check for a vacuum leak where the intake manifold bolts to the head... might save time and money.
Golf IV / Jetta IV :: VR6 - Random Multiple / Cylinder Misfire
Replaced my water pump March 2nd using the "From Below" method. Started the car after and the check engine light was on and water pump was no longer leaking. I drove the GTI to Advance (15 Mins away) it drove fine and I pulled two codes.
P0300 - Random Multiple/Cylinder Misfire
P0301 - Cylinder 1 Misfire
The car pulled and drove normally. The next day the car is misfiring badly. Hesitation and bucks when accelerating until roughly 3k then smooths out.
I will swap my coilpacks and check if the misfire moves as soon as I can get my hands on an OBD2 Scan Tool.
From what I understand about the VR6 :
-The water pump runs off the serpentine belt
-Camshaft timing is controlled by the timing chain.
-Timing chain is not affected by the serpentine belt/pulleys.
Questions :
-Can turning the Crankshaft Pulley affect timing?
-Can that be the cause of the misfire?

Golf IV / Jetta IV :: 1995 - Random Multiple Cylinder Misfire?
I have a 1999.5 Jetta VR6 12v, last week the car would not start. After some tests I determined the coil pack had gone bad. Replaced the Coil with a brand New aftermarket German made coil. Now 1 week later, driving at highway speed CEL came on, started to flash and obviously misfiring again. Ran Codes and now im getting these DTC's:
1)random multiple cylinder misfire detected p0300
2) cylinder 4 misfire detected p0304
3) ignition coil output 3 electric malfunction p1395
4) cylinder 3 misfire detected p0303
has this new coil gone bad already after a week?
New issue?
Plugs were replaced less than a year ago, wires were apparently replaced by previous owner about 2 years ago now. Crank sensor replaced less than a week ago...
Ford Super Duty (1999-2016) :: 2008 F250 - Random Misfire Detected On Cylinder 7
Truck Specs:
2008 f250 super duty 5.4l
78xxx miles
4x4
Automatic
Issue:
P0300 (random misfire detected)
P0307 (cylinder 7 misfire)
Let's start from the beginning...
I was getting the notorious 5.4l ticking sound. After doing research on this issue. I found that it could be a few different issues including:
Cam Phasers
VCT solenoid(s)
Loud injectors
Valves
Exhaust leak
Loose spark plug
The list could possibly go on, but these being top concerns or issues to look into.
I took it to my mechanic and wanted him to research the ticking problem. This was my primary concern due to it was getting worse over time. I didn't want to do more damage than what was possibly already done. I told him to go ahead and change the spark plugs while you're checking into what's going on. (I know those plugs can break and I didn't want to do that.)
At any rate... the plugs got changed to motocraft brand (I know the trucks can be finicky with the parts you put back into them so I went with the motocrafts to avoid any complications.) After the plugs were changed, he told me that the ticking was caused from a blown exhaust manifold gasket (yay me... not internal parts or anything too serious. Sweet!)
I had to reschedule to get the gasket done, but knowing what it was now I wasn't too concerned about driving it. So I did. The new plugs are also in the truck at this time. I drove it the next day and right away.. I noticed a misfire. Thought maybe the plug was bad. I told my mechanic about it and he said... Sounds like a COP to me.
So I get a new COP. Okay.. easy fix. Installed it and still got a misfire. Told my mechanic and he said get another COP. So I'm thinking.. "Okay.. get a new part to fix a new part.. sounds logical.. lol" so I do what he thinks might be best. I replace the COP with another new one and it's still misfiring. The new cops are also motocraft brand as well.
Okay... next step.. he claims it may be a VCT solenoid issue. At this point I don't care.. I just want my truck fixed. So he replaces the driver side solenoid. Still misfiring..
So after doing some research on the scanner... we locate some issues that are the exact symptoms I'm having. Misfire.. at low rpm.. during cruise control.. and a sudden at idle.
This information states for this drivability issue.. to spray injector cleaner/carb cleaner into the engine and possibly clean it out. Makes sense. He did this as well as changed the fuel filter. Also did a pressure test on the injectors to make sure they were good. They were. After spraying and cleaning it out, it was taken for a test drive and it seemed okay... but not perfect. The next day.. the misfire came back.
He said that if the misfire returns, that I need to contact the dealership and see if there is a pcm update. The dealership said there probably is but can't tell me until the computer is hooked up to it. (Of course there is a charge when it's hooked up) again.. whatever.. I just want it fixed. The truck is scheduled to go in next Wednesday for that. If that doesn't fix it, my mechanic said cam phasers possibly bUT still not sure for sure..
Passat (B5) :: Error Code 16684 And 16686 - Random / Multiple Cylinder Misfire
I was driving along and the engine started missing really bad. The whole car was bouncing around. At first I thought I had a flat, but when I stopped I noticed it was the engine. I checked the error codes and got 16684 and 16686 --- Random/Multiple Cylinder Misfire.
I had a problem recently with the vacuum hose broken and was causing an error code. Replace the hoses and it has been fine. Checked to make sure that the hoses were secure and they are fine. Doesn't seem to me to be related. So many problems for a car with 57,500 miles

I have a 2006 F150 4x4 5.4. For a long time it idled poorly and would take 2 trys to start. Today it started shuddering and the engine light came on. The engine light went off but it still runs rough and smells of gas from the exhaust. It is not very drivable and I can't afford to take it in. I have lots of mechanical experience but not with this electronic junk and need diagnosing the problem. I have a code tester and this is what it said.
