SOURCE: cylinder #4 misfired on my 2003 chevy trailblazer

You didn't mention what engine size or really a question either but am just guessing that you may need help diagnosing the problem. I'm going to go by the most common engine in the Trail Blazer and that is the 4.2 liter 6 cylinder engine. There are several things that can cause a misfire in a cylinder but the 2 most common are either a bad coil or a bad fuel injector. The most common of those is the ignition coil. There is a separate coil for each cylinder and each of them are mounted on a spark plug. In the first picture you can see what the coil looks like and as you can see it has a connector and a boot on the other end that goes over the spark plug. Each one have thier own mount bolt as well. Also below is a picture of were each cylinder is at by number. I would just swap out coil number 4 with the coil for number 3 and put the coil that you got from number 3 and put it in number 4 (hope you got that) Plug all back up, clear any trouble codes, run the vehicle and if you end up now getttting a misfire in number 3 instead of 4 you know the coil is bad. If that doesn't work then you may be looking at an injector but there are several tests to rule that out that I am not going to post right now. I included some other pictures and instructions that should help. If you do happen to have the 8 cylinder engine (5.3 liter) this also has different coils for each cylinder but the set up is a litle different. If you need any other help or need the tesing procedures for an injector, feel free to comment/reply here or you can email me directly at csautomotivecars@att.net with all your information and I will be happy to try and help. As I said the coil is the most common and I think this will clear it up once you diagnose it. Hope I was able to help.....

Why is my # 4 cylinder missing on my 2004 chevy trailblazer


Most likely solution is to replace the s[ark plugs and check the ignition coils boots. The #4 cylinder plug has probably has a carbon track down the side of the porcelain part of the plug which will cause the cylinder to misfire.

Spark plug one and four which one is that 2004 chevrolet trailblazer six cyl.


Number one is closest to bumper then just count back they go in order 1-2-3-4-5-6 then the firing order is 1-5-3-6-2-4 also if your having a misfire check for lose wire and if I remember right those had a problem with water contaminating the coil packs check for white on the coil and on the boot inside and out, if they are chalky you need to replace the contaminated parts and the seal to keep water out at the back of motor where hood closes.
