@Hey You

no aftermarket parts on the truck!

I remove Cold air intake, Jet performance chip take it out!

Everything is back to stock original!

 

Still have the same problem??

Cold air intake shouldn't matter.....

 

@Hey You

still have the same problems over 68km/h and so on if i press slightly on the gas to keep the speed steady it jerk missfire or shutter its really annoying!

I did the whole muffler yesterday neuf Y pipe catalyseur neuf muffler new mid pipe new tail pipe nothing change still have the same problems!

only parts have haven’t replace yet its the MAP sensor !

any input would be appreciated!

 

@Hey You

I dig a bit more onto the cylinder number 6 missfire

found out my new plug champion RC12LC4 copper plus had the tip bent all the way down touching the igniter of the spark plug gap was 0.00 i set it back to 0.40 everything seems to work fine now 🤔🤔 the color was brown light

what could have cause this ???

Ive check all the other 7 ones and everyone of them is fine and have the right 0.40 gap

 

Did you gap the plugs when you installed them? (when they were new...)

 

@Hey You

Yes i did gap them all to 0.40.

Now the truck never runs as good as this i went for a long drive unbelievable the difference!

and my milages by 100km

went from 29-30 to 17l/100km couldn’t believe how well it’s run!

 

But it still gets stupid if you move the gas pedal?

 

@Hey You

nope not at all now everything is perfect if i press lightly on the fas no more missfire jerking or shudder

run really fines never runs like this before !

 

Awesome.
