    I have a 302g and was having similar issues off and on and it would be hard to start when it sat for a while so I installed an electric fuel pump and it's fine now going on 2 years.

    Re: Trailblazer 302 acting up

    Well I got it from the shop today. I was correct in my initial diegnosis that it was running rich. It was the oxygen sensor in the muffler. It was making the EFI system feed too much fuel to the engine. So $246 later I have a running welder. I have learned my lesson with this EFI engine and will not try to fix it without putting it on a scanner . I am happy because it could have been far more expensive to fix.

    Just curious, but how much labor time was on the bill? Diagnosing that sucker had to be a bi*ch I would think.

    Re: Trailblazer 302 acting up

    It probaably a good thing I took it to a shop because the guy that worked on it said the oxygen sensors never come out easy. They had to use an impact to get it out and then chase the threads because they get screwed up from getting the sensor out. I doubt that I have the correct tap to chase the threads so I would have had to buy one.

    To answer AWG, they charged me 1.65 hrs labor and the sensor was $104.00 They said the code for the oxygen sensor was on with the scan tool. They must have run it quite a bit because they used a 1/4 tank of fuel .

    When Miller wins ? They WIN big time. The rest of the time they use fanboys of blue to detect their many failures. When Lincoln releases a product it's generally solid. When Hobart releases a product they dont change it for decades. You decide

    Doesn't matter what color you run with, they've all put out some great machines and they've all put out some lemons. I will agree though, seems like they use their distributors to run their field trials AFTER it's released and to help make lemonade.... been there, done that too many times.

    Hi Gary,

    I’m having a similar or possibly the exact same issue with my trailblazer 302 EFI so I’m curious if you’ve resolved your issue and what the problem was?

    My machine will suddenly start running very poorly almost like the choke was stuck on (even though it doesn’t have a choke).
    This will happen either when a load is applied and the engine attempts to switch from low to high idle, or sometimes partway through burning a rod (already in high idle).

    Any insight would be greatly appreciated.

    Nevermind I see now that your issue was the O2 sensor. However do my machines symptoms sound similar to the problems you were having?

    Where did we get the idea about the Hobart. I had a test unit for 6 months, maybe more before they put it in production. They wanted to know every glitch, even tape on the box.

    It does sound similar to what mine did. I would not try to fixing it without having it scanned. The time you will wast is not worth it.
