SOURCE: mercedes c200 elegance 1996 model mis-firing on cylinders 1-4

I beleive your firing order is 1 3 4 2. 1 and 4 are companion cylinders-meaning the piston is up or down at the same time i.e. compression and exhaust stroke both pistons are up and even on the exhaust stroke the ignition fires in order to burn unburnt fuel/ h ve you checked your trigger. There is a good coil testing tool that is placed over the coil and has a magnetic pickup that allows you to see if the coil is being triggered-just because you have power doesn't mean that you will have spark. I would replace your ignition wires and look at your wiring harness very carefully- if it is very brittle and you see bare wires exposed that is your most likley problem because the trigger is working for 1 and 3 and has the crank senser input for all for spark plugs and the cam senser is used for ignition advance and your fuel injection system. try wiggling your harness and see if your coils start to work. wireharnesses are a major problem on mercedes benz vehicles of that era. I hope I have been helpful

What causes the engine to miss fire on #2 cylinder?


If you shoot me your year I might have the info you need. And - depending on your year - the 94ish years had TWO coil packs for the 4 cylinder - 8 plug wires basically. When any of the leads of either of those coil packs goes out - youre going to experience a miss condition. If it's the v6 - you've got a cam sensor that can cause that type of action - and have you checked your throttle positioning sensor? If that goes out - the ecu will get mixed signals and can act like that as well. If you can tell me the year I'll see if I got the info you need. All the best.

Dead miss on one cylinder 99 sl2


A quick way to check the single coil pack if you know for sure which cylinder is miss firing and its setting a code you can swap the coil pack to another cylinder and see if the miss changes from one cylinder to another. If it travels to where you moved the coil then the coil is bad,if not you have other problems.

Hesitant acceleration intermetion


What engine does it have in it, if its coil pack over single coils per cylinder. Pull plug wire or coil out of last cylinders on passenger side, these are known for getting water in them that causes a miss in acceleration

92 explorer sport missing at idol and acceleration


The 1st thing to replace is the plugs and plug wires, they are goood for about 100,000 miles, then if that doesn't do it you may have more serious concern. issues

My 2004 chevy trailblazer is missing badly. Had them read the code for me at auto zone and it said I had a miss fire on the number one cylinder. I changed the plugs and it is still missing badly


Try moving the coil pack from cylinder 1 to another cylinder (swap locations) and see if the same code comes up. If code is different, then coil pack is bad. Other reasons for miss; bad injector, poor compression.
Also, I know you changed plugs already, but always use AC Delco 43-103 plugs on this vehicle.

What is a firing order


This is a quick explanation:

1996 Dodge Caravan
3.3 liter


c17hydro_162.gif

The big rectangles are referencing the engine, the cylinder associated to it's "firing" are the colored circles, and the are also the location of the spark plugs....the smaller lego-looking block is your coil pack. The spark plug wires run from the coil pack to the spark plug on the engine. The wires match 1 to1 or black to black...and so on....

When these are matched to each cylinder/spark plug and it's wire leading to the matching coil pack position, this is it's "firing order". If one of the wires is "crossed" meaning, not 1 going to 1, then the engine will "miss-fire".

I just purchased a 93 Crown Victoria with the 4.6 litre V8. It idles ok but bucks under any acceleration...misses badly. To the point where I went over an overpass and begin losing speed. All the spark...


your problem is not wire location, it sounds like bad wire or wires, also those engine are pron to bad coils,but i think you should start with wires,also check fuel filter or just replace if you can check fuel preasure.hope this helps.

I have 02 L300 3.0 with cylinder1 miss fire.I


Swap the coil pack to another cylinder if it is individual. If not, you should be able to pull the wire away from the plug and hear it fire. If not, you have a bad coil. If so, I would look at doing a compression test and possibly a leak down test.
