The question would be is the cylinder missing because of no spark, no fuel, or no compression ?
Was the wire giving the plug spark ?
Was the plug wet or dry for fuel ?
Does the cylinder have normal compression ?
Is the check engine light on ?

I have a 1998 gmc jimmy 4.3 6cylinder 4x4 I blew


What I've seen done to test an injector is to pull it, and swap it for another cylinder. If the miss moves, then the injector is bad. If the miss stays on #5, then the problem isn't the injector.

What do I do next? My 2001 olds alero 3.4l v6 is misfiring constantly. Scanned obd2 error code p0301. Already changed spark plug, wire, and coil for cylinders 1 and 4. Still have same problem.


I recommend checking all injectors and O rings on the injectors if an O ring cracks air can raise Cain with misses so can injectors another thing is cam to look at will cause a constant miss but only on 1 cylinder at a time but doubt its the cam. check injectors and O rings also pull 1 plug wire at a time with wire pliers while engine is running and find the 1 cylinder that is giving you the problem when you pull the plug wire that is missing the engine will smooth out then that cylinder is your problem wear rubber gloves with the plug wire pliers so you dont get bit let me know if i can help please rate my solution as this is how i earn my achievements on fixYa thanks.

Car idles rough, sometimes dies in reverse, it's worse in cold.


A cylinder that doesn't fire could be 1 of 3 things: no spark, no gas, or no compression.
Sure, it could be a bad injector, or clogged, but you should do some tests before buying an expensive new injector. You should first check the injector circuit on #2 cylinder. It's a pretty simple circuit, really. Each injector has 2 wires, a power wire and a ground wire. The power wire is one wire, which is spliced to each injector, and has battery voltage on it anytime the ignition switch is on or in "run". Each injector's ground wire is a separate wire going into the computer. When the computer internally grounds for a split second that injector's circuit, the injector sprays fuel out a tiny opening, a nozzle. You can check the circuit for #2, both the power wire and the ground side of the circuit with a test light. Post back and ask, if you want me to explain.
You also might want to check the compression in #2, just to assure you there is no mechanical problem causing a loss of compression in that cylinder.

Dead miss in cylinder 2


I would want to know if you have normal compression on all 6 cylinders, and if the other 5 are firing correctly.
Usually when you pull a wire and the engine smooths out, you have another cylinder miss going on at the same time.
How many trouble codes do you have in the computer ?

2004 GMC Envoy misfire


If you pull the #2 plug out and start the engine do you see a spark? You didn't mention if you checked the wires or not, but it could be a bad plug wire. If there is a spark, I'd try and see if the #2 injector is actually firing like you mentioned above.

I have a 1999 Pontiac Grandam that is pulling code P0300. I have changed the head gasket, plugs, boots, both coils, ignition module, crank and cam sensor's, had to get a new timing chain tensioner and...


The only thing left would be fuel. Check fuel pressure , replace the fuel filter, and check the injectors(ohm's from 11 to 15) and the injector harness. Mostly on the harness make sure you didnt pinch a wire putting it back together, especially the map and coolant wires.

1987 cressida missing


Start with testing the injectors for pulse. Get a NOID light they sell the at almost any auto parts store remove in get plug from injector and plug the noid light into plug look for constant steady (pulse)lighting of noid light. Check all six injector on your strait 6. If all is good remove parke plug wire on at a time from cap and look for increased shaking and less when it replaced(Make sure to use wire puller with rubber insulation to avoid being zapped by spark from coil) Note cylinder with no difference or change when wire is removed. Those would be the problem cylinders. Then get a compression guage and check all cylinders for compression by removing spark plugs and attaching guage to each cylinders, make a not of each cylinder's reading. NOTE THEY SHOULD NOT BE MORE THAN 10 PSI difference in cylinders. Make note of low compression cylinders if any. If compression is good all around spark plugs are good, good ignition wires and you have good pulse pattern from you noid light. The only other problem is BAD INJECTORS and those would be the ones that didn't change when you took off the wires. I have work on these old cressida alot my self. Good Luck contact me if you need more help and if I solve your problem leave me a FIX-YA comment.
