Got another random misfire this time P0305, I’m going to suspect it’s another fuel injector going bad. Yes I’ve gone through this on the #2 cylinder, 3k miles ago. I have new plugs and wires. All Fuel injectors where cleaned and flow tested good. However one injector was bad at that time.

Has anybody use this company to replace all 6 fuel injectors. Timmy the tool man has used them.

i have used them and have no complaints. Actually getting ready to send them another set for a different 4runner to get serviced. I see now they offer a high performance injector replacement with no core charge. I do not know what they are or if they help our rigs at all. would be interested to know

Check out Osidetiger. They have upgraded fuel injectors that are reasonably priced. I have a set in my 88 4Runner and am planning to install some in my 99 soon.
 
I went through them for a set when I was getting a misfire.
They have great customer service and was prompt to answer any questions I had.
I plan on sending them a set of Bosch injectors out of my Mustang for cleaning.

so not meaning to hijack this thread....is related...what exactly is the "upgrade"
that motorwest lists. Going from brown to gray body color ?
on BMW's the upgrade was going from 2 pintle to 4 pintle ( holes for better spray pattern and mix with air). I see in picture of motorwest the upgrade is still a 2 pintle.

I know this was posted a while back, but I did want to answer your question, thanks for asking!

The Denso upgrade set we offer is far more reliable in the long run, IF you're going with refurbished injectors (obviously new would be ideal were it not for the insane price of genuine Toyota units). Without going too much into detail, the OEM brown injectors fail at much higher rate than your average injector (this is why you see so many misfire issues in this platform with the 3.4L). The electrical component degrades over time and the injectors die eventually. The issue is there is no way of predicting when that will happen. So if you purchase a set of refurbished brown units, it's quite possible to have one die soon after as you have no idea how many miles are on each of those. The Denso replacements we offer don't have that electrical issue at all. In fact, in the thousands we've refurbished, that's never been an issue, not a single dead injector.

If you still need more clarification, please let us know.

As for the 12 hole units, I'd be careful about running those, they were not designed for the 3.4L intake design.

I'm looking to proactively service/replace my injectors. Would it make sense to buy the $249 grey set and send my factory injectors in for refurbishing?

Motor west thank you, I replaced my injectors with ones from your company and they work perfect and fixed my issues
 
Hello everybody! Recently did my injectors from OE to motor west and noticed they are super loud. Just curious if anyone else has noticed the same. Thank you
