V8 engines have a very different tone than a four-cylinder engine. If your 4-cylinder engine is misfiring on one cylinder, it may sound like a three-cylinder engine. If your car's sound is extraordinary, it's most likely misfires on every cycle that you can hear. 7 Common Causes of an Engine Misfire An engine misfire code might indicate a problem with a specific cylinder, or that the engine is running lean. Depending on the diagnostic tool being used, it may show how many misfires occurred within a certain number of cycles, or the engine RPM when the misfire occurs A misfiring cylinder can cause a proportional loss of power. For example, if one cylinder misfires in a four-cylinder engine, the car will lose 25 percent of its power. Driving with a misfiring car is not safe. Here are 4 signs and symptoms to look out for if you believe you have a misfiring cylinder: 1. Loss of Power Accompanied by Abnormal. The misfire may happen when it is cold out or while the vehicle is carrying a heavy load. Other times it may seem like the cylinder misfires randomly, with no pattern
If the misfire moved to cylinder number 4 (P0304), then you have determined that the coil pack is faulty and needs replacement. You can do the same test with the spark plug, i.e., move cylinder 6 plug to say cylinder 3 and if the misfire is now P0303 then the plugs are at fault How to repair P0308 code Cylinder 8 Misfire Detected. What is the cost to diagnose the P0308 code Labor: 1.0 The cost to diagnose the P0308 code is 1.0 hour of labor Cost of Fixing Cylinder 3 Misfire. Your mechanic will have to diagnose the problem first before fixing it. If the problem is the spark plug, the total cost of repairing/ replacing it will range from 40 dollars to -640 dollars. If the fuel injector is the problem, labor cost plus repair may cost you an average of 1500-1900 dollars
A lean code will not cause a misfire unless the engine has a vacuum leak most often at the intake manifold gaskets. A misfire code looks like this: P0300-P0306 for 6 cylinder and P0300-P0308 for a V8. P0300 indicated a random engine misfire, this can be caused by all kinds of issues The cost to repair a cracked cylinder varies between different model cars. The average minimum cost you can expect to pay is $500, but with parts and labor costs it could go up to about $1,000.

Most shops will charge about $80.00 for a 4 cylinder and about $140.00 (US) for V8 engine's
Now, if you are thinking what causes a cylinder misfire, well, it is the bad spark plugs or the imbalanced air or fuel mixture, which is responsible for the misfiring a cylinder. Understanding The Risk Of Driving With A Misfiring Cylinder. It is the car's cylinder which is an essential part of the engine and where the combustion occurs Finding The Engine Misfiring Cylinder. In the case of a steady misfire, isolating the misfiring cylinder is the first step in diagnosing the problem. The old-fashioned method for finding a weak cylinder is; to temporarily disconnect each of the spark plug wires, one at a time, while the engine is idling Here we have a P0301 cylinder misfire code on a Chevy 3.1 liter engine. The check engine light was on and flashing at times and the computer had a pending P0301 cylinder one misfire code. I pulled this code from the computer using my Actron Pocket Scanner. It works great because it is extremely fast (just plug it in and hit the read. If the misfire moved to cylinder number 4 (P0304), then you have determined that the coil pack is faulty and needs replacement. You can do the same test with the spark plug, i.e., move cylinder 2 plugs to say cylinder 3 and if the misfire is now P0303 then the plugs are at fault Next I swapped the coil on #5 and #6. Within a couple days the misfire was back. This time the codes showed 02, 03, F1, F3 and (Ignition Coil #4 and #6 and Misfire Detected Cyl #4 and #6). What the heck? How did cylinder #4 get into the equation? If anything I expected a misfire on #5. Bentley's manual wasn't much help and I'm now at a loss
I recently purchased a 2014 Ford F-150 8 cylinder 5.0 It has high mileage 105k. The check engine light is on and the motor shakes when idling though it pulls strong at higher rpm. I had it checked the computer indicated an issue with cylinder #5. When tested further found that the compression on that cylinder was low 75psi the mechanic also put some oil in and tested again It was the intake manifold runner control on the secondaries. the control unit was broken, allowing more/less air into the cylinder, causing said cylinder to misfire.

A Check Engine Light may illuminate indicating a Cylinder #3 Misfire. This normally occurs in hot weather after the vehicle has been driven, parked for ten to twenty minutes, and then restarted. Heat from the exhaust vaporizes fuel inside the #3 fuel injector and causes the misfire Any cylinder with this compression (or lower) value will misfire. Since cylinder #2 is only producing 95 PSI, I can now conclude that it's 'dead' and causing a misfire. To find out if the lowest compression value you got from your engine compression test is within a good range, you'll need to do the same calculation P0307 - Misfire cylinder 7 (V8 SHO) P0308 - Misfire cylinder 8 (V8 SHO) P0316 - Misfire detected on startup (first 1000 revs) Cylinder numbering (applicable to all Ford V6 engines 1987-2007): Firewall; so delaying replacement may cost you your engine!

But that isn't necessarily the primary problem, because for low-performance engines with an already-low cylinder pressure -- you may have lost enough compression that fuel burn becomes unstable. The result is an intermittent misfire
Ive got a 2002 dodge ram 1500 slt w/4.7L engine. I am getting a misfire on the #6 & #8 cylinder. I have changed the plugs with bosch platinum 4 (all 8) and have also changed all 8 coil packs and am still getting a misfire. I pulled out those 2 plugs again and there is a carbon buildup on both. I also checked the others and they seem to be clean But the most common are 4-cylinder, 6-cylinder, and 8-cylinder. When one of your cylinders misfires that causes a power loss in proportion to the cylinder dropping out of the entire combustion reaction. That means if one cylinder in a 4-cylinder engine misfires, you just lost 25% of your power. What Causes an Engine Misfire
The mechanic found a misfire on cylinder 3 and then moved the spark plug and COP from cylinder 3 to cylinder 2. That is, the misfire followed the spark plug and coil. I went home and changed out the COP on cylinder 2 with one of the originals. It did not fix the problem. I bought a MotorCraft spark plug and put it in cylinder 2 Just recently it started to throw codes. I hooked the computer up to it, and it is reading P0305-cylinder 5 misfire. I replaced all the spark plugs with Bosch Platinum 4's and cleared the codes. The same day, it threw the same code. So I got a new coil and replaced the one in cylinder 5. Again, cleared the code and came back If OBD II equipped, the check engine light will be on with one or more of the following misfire codes: P0300 Random Cylinder Misfire. P0301 Cylinder #1 Misfire.

P0308 Cylinder #8 Misfire Extreme cylinder misfire events can cause catalytic converter damage. The malfunction indicator lamp (MIL) will flash when the conditions for catalytic converter damage are present. The Diagnostic Trouble Codes (DTC) P0301 through P0306 (or P0301 through P0308) correspond to cylinders 1 through 6 (or 1 through 8)
Monitored engine data with scanner and verified misfire on #6 cylinder as well #8 cylinder. Removed #6 and #8 spark plugs, performed simple/basic compression test on those 2 cylinders, results: #6: 0 psi #8: 175 psi; Tested Cylinder #6 further: leak-down test and wet cylinder compression test - still: ZERO compression This engine misfire didn't arrive only under load: It could as well show up at idle as when accelerating. Of course, a misfire while accelerating meant the Toyota V6 got even slower. The sensible method is to gather available knowledge about the engine misfire, focus on steps necessary to eliminate suspects and let the process guide you to.
