Hey Folks! Welcome back to the channel. In this video I track down a P0300 check engine code for random engine cylinder misfire. Below is a link to the inexpensive OBDII scan tool that I use.

I just got done swapping my engine for a used one and I think this video tells me exactly what to look for. I’ve had my hood popped open while working on this and not latched and it’s been raining a good amount here in California recently. I’ll be looking at this first!

This is a common problem with these vehicles. Replace the seal under the hood where your windshield meets the hood.

@KevinNadeau 2 года назад

That's the sense I'm getting about this issue. Do you happen to know the part number for the seal?

@fsu3784 2 года назад

@@KevinNadeau well it keeps erasing the number for some reason

@joshc4113 2 года назад

@@KevinNadeau Hey Kevin did you end up having to replace the valve cover gasket or did changing the seals on the coil packs work in resolving your misfire? I am also having the same issue lol

I have a 2004 trailblazer with 230000 miles on it and I'm also having a misfire, but it's intermittent and that's one thing I'll have to check is for moisture. Thanks

@KevinNadeau 2 года назад

You have many miles ahead of you with that truck. Good luck tracking down your misfire.

What makes a sticker placed on the window a "modification"?

@martinlorenzo2300 Год назад

friend help me I have a car of the same brand that you are fixing but I changed all the spark plug coils and the same code appears p0300

@KevinNadeau Год назад

I’ve heard of guys replacing the VVT solenoid and the misfires went away. Have you checked compression on the cylinders? You could also check for vacuum leaks. Best of luck👍

@ItsLivids Год назад

In my 2007 Acadia I just cleaned the throttle body cause it got backed up and all good

@lilgrizz7109 2 года назад

So did fix it or just temporarily cuz I’m having this problem right now , You didn’t change spark plug aswell right correct?

@KevinNadeau 2 года назад

So far its still working fine. I could have also replaces the weather striping on the cowl, but didn't do that. I did not replace the spark plug.

I have this problem. I had everything replaced. But it still didn't fix the problem

@KevinNadeau Год назад

There are probably more than a dozen things that could cause P0300 code. Did you change the spark plugs?

@RetroCaptain 8 месяцев назад

There's a few sensors that become fouled and fail with old age and need replacing or at least cleaning. They are really great engines but cannot withstand a lack of astute maintenance.

@paulinagourley5978 Год назад

Also what is a power train.

@KevinNadeau Год назад

A powertrain is an assembly of every component that puts your car into motion. It includes engine, transmission, driveshaft, axles, and differential.
