It may just be a coil breaking down or a bad spark plug. Try swapping one of the coils over with the faulty one and see if the misfire happens on that cylinder and cylinder 2 runs fine. If it does then swap the faulty one for a new coil. Don't know about your car but most now have individual coils for each cylinder that fit directly onto each spark plug.
This could have several problems. #1 Fuel pressure due freezing water in fuel lines add thermal aid or rubbing alcohol . If you have access to a pressure gauge there is a service fitting on fuel rail that you can test pressure while driving and see if the pressure is gone when car dies this could lead to fuel pump electrical or more restricted lines. #2 intermittent sensor failure Mopar uses 2 sensors to control spark and fuel lose one could lose spark lose the other lose injection with a scanner they call it C/C sync ok (cam/crank) if no then check for each parameters for display.# 3 relay controls ASD and FUEL pump for voltage drops.
The removal of # 3 & # 4 tells you those cylinders are
contributing the most ,as removing the wire causes the motor
My guess is that the other cyl #1 & #2 are not firing at all, if there
is no change
If you had a V6 or V8 it would continue to run,not so with only
Learn or study the ignition system & replace any ignition control
module that fires the first two cylinders
Get an HEI Test Spark Plug & put the plug wire to that & ground it
& see if you get spark,check all the plug wires one at a time.
Don't forget timing belts that are worn & slip,battery voltage,alternator output & A/C Ripple coming out of it
I would check compression or better yet, do a cylinder leak down test.
Could be you have worn valves in #1 & #2 thus little spark
Check fuel pressure at motor with a gauge
Try the engine temp sensor! I had a renault 3.0 v6 24v in which ford used to use in the old monsters like ya granadas n so on. Its should be on ya cylinder head somewhere and the plug should be green in colour. If ya find it, start up ya engine n pop ya bonnet. Remove the plug, the engine will run smooth strait away. If this is the case, as a temp solution spray with WD40 to to clean n provide a propper connection. In the long run tho ya will need a new sensor which screws into the cylinder head. This sounds like a big problem but it aint n the new sensor can be found on auction sites n ya will prob be able to pay for it with a single note. Hope this helps. If not try ya points.
Have you verified that you have good fuel pressure/volume, good spark and that #2 cylinder is indeed missing? Sometimes a misfire code on one cylinder doesn't make that cylinder the culprit. Verify that #2 isn't firing by unplugging the injector while it its running and noting if there is any difference in RPM. Also use a spark tester in line with #2 between the wire and the plug to see if you are getting a good spark. Hope this helps, James Booth
check your vaccum lines and injectors I had the same problem the injector would put gas in the cylinder but not keep constant spray so it would puddle and ignite creating a back fire also check your coils and make sure you are getting spark to every plug ...
hope that help I have the same car 1995 chevrolet camaro 3.4 liter v6 automatic
see your spark plug cables they have writen in begining or ending what number spark is. or in the joint electrical box from they take electricity have writen in it in any output what number of cylinder cable spark id going.
