Misfiring, loss of power, abnormal engine vibration

that sounds like an injector. or a bad connection on an injector.

 

im fairly mechanically inclined and i changed my injector in about 2 hours. mine is a v6 and the intake had to be removed. its pretty easy just take pictures when you take anything off. then you can just scan through the pictures when you are puttin it back together.

 

The injectors are fairly easy on the 2RZ. It's a tight squeeze if you got big hands to undo the clips for the wiring on injectors..but it's doable. You have to undo like one bracket that is just holding a wire loom onto the intake manifold.

That's it. It took me about 40 mins after some cussing and yelling at the truck to get them out with the rail and everything.

I'd help if I was closer and had the gas money to get to you.

 

I can't remember but the actual COILPACK runs cylinder 2 and 3, the other runs cylinder 1 and 4. Just follow the wires to the plugs..it'll tell you.
Worn or torn wires can cause misfire, you'll get intermittent spark because you have a short..it's gotta jump across and arc..causing intermittent spark.

The only way to tell if it's misfiring on different cylinders is to clear the codes, and if one pops up again..scan it and it'll tell you what cylinder.

You might be able to tell by the spark plugs if you take all out and clean them..see if any are getting fouled or are abnormal looking after swapping coilpacks.

 

Just to rule out my own ignorance, the cylinders are numbered 1-2-3-4 going from front of engine to back, right?

I replaced the coils on what I assume are 1 and 4, but if I should have replaced one of the coils in one of the center cylinders then I never tried that.

Checking the codes involves the hassle of going and taking the truck to wheelworks, and paying them to tell me what the truck is saying. Unless someone in the city has a reader I can borrow.

 

Yes

and yeah unfortunately but it's what you gotta do..

Truck ever overheat?
Ever check the valves?
