I've been working on my trailblazer with a cylinder 1 misfire so glad I found this I'm going to use it as a sort of guide to get my fuel injectors out. Thank you!
Not sure about Ashlee’s but mine is still running good. Which ever cylinder Is misfiring. Clear the code then switch coil for the cylinder that is misfiring with a coil from a cylinder that isn’t. When the code comes back, see which cylinder is misfiring. If it’s the same cylinder as before, then it’s the injector. If it moved, it’s the coil.
why not replace all 6 of the injectors since youre already there? just figure it makes sense but maybe not necessary ? Thanks and great vid!.. actually nvm, I just looked up the price for one lol
you said it was leaking from the rear main seal? did this stop that leak or did you mean that no other leaks started?? i think mine has the same problem. i dont have a power steering leak but i can tell sometimes there is strain on the pump.
Thanks for video, it seems like cylinder 4 is my pain in the ass now. My husband did spark plugs, coil, and last but not least we got the fuel injector next. I am debating just taking it to a mechanic.
Great video. Very informative. My 02 Trailblazer with 257k miles on it isn't specifying which cylinder is misfiring. Just gives me a P0300 code and the check engine light is constantly flashing. I replaced all of the plugs and coils and still didn't help. Would this be worth trying?
Thank you I will looking for a good video on how to take the manifold out because I was changing my coil packs in the boat broke on the last one, by the firewall can not see it so I will have to do all of that in order to get to the little stud that's hanging up
I've got a P0301 lean code. installed new plugs and faulty coils but still misfiring. I dunno, should I go with the O2 sensor or fuel injector? Also I have a very bad leak from valve gasket, waiting for the parts, coming next week.
@@Primer2toneGarage hey thanks for the advise. I also found the small pipe black pipe below the air intake connects to valve cover is broken, could it be another reason for vacuum leak? what is that pipe called anyway?
@@Primer2toneGarage turns out coil #5 was not working properly, did a mistake and bought a cheap one, should've gone for Delphi. Thanks for your support buddy.
The throttle body regulates how much air goes into the engine. The throttle body also creates a vacuum in the intake manifold which is useful because many components utilize vacuum to operate (EGR, fuel pressure regulator, brake booster, and many more I can't think of right now).
2 days with that pain in the ass intake man... that last bolt in the back by the firewall is a bitch!! He didnt really show it but u can see how his arm is snaked between the brake booster and power steering or brake fluid resevoir and firewall and engine
Sorry for the late response. If I had to do this for a customer, my labor would have been around $400 but this was my sons truck and it was a labor of love and education.
@@danielmonar8925 there might be, i havent looked yet (still need to do it to mine, havent bothered its cold season) but its in the haynes manual. remove center console, remover ac control trim plate, unscrew the unit and unplug for 5 minutes plug back in and it should recalibrate.
I did it a few months ago on my girlfriend’s envoy, which looks exactly the same. All you need to use to do is a fuck ton of swearing at the manufacturer and after a couple of hours and a billion different combinations of sockets/ratchets/extensions/swivels, etc. you’ll get it out.
@@RedneckMudder88 I have a work platform that I stood on and laid across the engine bay. Each of those bolts required a different socket/extension/ratchet(hand/electric). My recommendation is just sell the car and buy a new one 🤣
