REPLACING INJECTORS....Star brand from standard products for 2008 LMM only $800?!!

Is testing return rates an easy job yourself or can it be done with efi live? I will try to contact Tony....thanks hondarider!

No you need a kit to see just how much is comin out. Its not very quick to do either

Doesn't this truck still have warranty? Or does it have a lot of mile on it?

 

[vincefmx]

No warranty...has 162,000 miles

You need the fuel line adapters for the top of the injectors. The rest you could build on your own.http://www.toolsource.com/injector-flow-test-adapters-p-126335.html?osCsid=mm7sheom1i5i0fenqn6l7fu7m5

Does the truck have a chip or is it programmed? Possible fuel starvation, in need of a lift pump.

Well guys, return rate on the injectors are all good....came up to Taylor AZ to Williams bros. great people and probably the most knowledgable shop in AZ I've found. Looks like its time for a lift pump, they have the FASS in stock here.

What all has been done to the truck? If you fill out your signature it helps others t/s for you. I don't think a lift pump will help a rough running engine...

 

[vincefmx]

Will fill out my signature...your right that would help out! As for the vibration/roughness...got her up on the dyno an the driveline was all over the place....u joint was half gone on one post! Should solve the vibration

 

[vincefmx]

I suggest to anyone who has this same issue to go to a shop with a dyno capable of producing a load and gettin the code to trip, then check injector returns immediately after, once the fuel is hot enough the return rates magnifies, and the truth is shown....one bad injector on drivers side, time for a recall from gm on their pos fuel system!

It's a Bosch fuel system, not GM and one bad injector in 162,000 is not the end of the world... Just be glad it's not a LB7, they get really expensive to repair. I feel that injectors are wear items and only last as long as the quality of service and fuel they have received.

I agree. Just be glad that's all it was.
