Which engine is this ?
If you stand in front of truck with the hood open you will look to your left.
The # 4 cylinder is the 2nd one back from the front, if this is a V8.

You need to run a compression check on the engine, no cylinder should show a pressure reading of more than 5% lower than the highest reading observed on any cylinder. Also have you verified number four cylinder is actually getting fuel injector activation, hook up a 12 volt probing test light (see picture below) and probe the connector to #4 cylinder, the light should blink rapidly when the engine is running, this indicates the injector is operating and delivering fuel. I also suggest you have the dealer run an electronic cylinder balance test, it takes a special tool but well worth the money.

2 cyclinders are working out of 4


You mean without taking it to a shop for repairs, or at least some diagnosing? Check for spark on all four cylinders. If two do not have a spark, the problem is in your ignition system. Possibly the ignition coil for the two not working.
If all four spark plug wires do have spark, it could be a fueling problem to the cylinders not firing, or it could be an internal mechanical problem in the engine. Then you would need professional help.
Google or watch a vid on you-tube for how to check for spark, if you are not sure.

About the only thing that would make all 6 cylinders flood out is the fuel pressure regulator or a computer problem. You say you have checked the regulator, so the next step would be to check the injectors for a short to ground.

1998 altima runs fine idol hesitates &sputters under load


You may have a check engine light on which would require you to have the computer scanned for trouble codes. The codes would help direct you or a mechanic on what to test.
A cylinder miss could be ignition, fuel, or something mechanical.

Do you have spark at the number four cylinder? Check that if spark is present , then you should swap the injector from four to five and see if the miss goes with the injector. If not then you will need to test the engine compression .

My 2001 oldsmobile alero has a cylinder #4 misfire


The misfire can be caused by an open injector , injector pulg or circuit, bad spark plug ro wire lost compression as a burnt valve blown gasket ( antifrezze foulingthe sparplugs ) Low compression from overheating over mileage or flooding from injector leaking. Take out the number 4 plug and any other and compare what they look like if they don't look the same swich them and see if the miss moves to the cyclinder that the #4 plug moved to. If it does run good or misses on the new cyclinder change the spart plug with new and then look for loss of coolant or oil on plug wire carrect leak and try again

Check engine light, on and running rough


This misfire is most likely due to bad injectors. Check injector pulse with a NOID light. If pulse is good you need new injectors. However before you do all of this get a compression guage and check compression on all cylinders. The numbers shouldn't be more than 10 psi difference in all cylinders for example if cylinder# 1= 160 psi cyl#2=168 that's good but if cylinder#3= 176 and 4=179 there is a problem with 1&2. bad valves or bad head hasket etc. Good luck and thanks for using FIX YA.

2003 with 3-0 well maitained. truck misfires at slow speeds.mechanic put computer on it and it indicated misfired on #1 cylinder at 1000 rpms changed wires didnt solve the problem. engine light still comes...


A misfire on this type of vehicle can be due to 2 factors if it missing spark it will trigger a misfire code and it you have a bad INJECTOR. Most misfires are due to missing spark but there are quite a few in my experience that were due to bad injectors or bad injector wiring. To check this you need a NOID light disconnect injector wire on suspected cylinder in your case #1 and connect wire to NOID light (engine must be running for this) Your NOID light should have a consistent flickering light going while vehicle runs at idle. If light its NOT flickering at a steady pace and flickers erratically. THE PROBLEM IS A BAD Injector wiring or a bad computer. If light flickers consistently and in a steady pattern then YOU HAVE A BAD INJECTOR. Replace injector and that will solve this problem. I know this is a lot of info but It will help you alot. Good luck and thanks for using FIX YA
