Diagnosing Misfire

Hey guys im new to the site. I picked up a 96 3.4L ext cab Tacoma two weeks ago. I found the truck on craigslist near Philadlephia and it ended up that it was an old friend of my grandmoms. I purchase dit from the original owner 99,650 miles on it, it is an awesome find! Only one problem driving it for a few days the light came on and the truck started to sputter while idling. I took it into my friend who is the service manager at Toyota. They replaced the plugs, wires and rule dout the coil pack. I dropped it back off last night they think it is the fuel injector, I think this is a rare occurrence, but I thought I should share this with the group. I hope they are right with their diagnosis! I dont feel like dropping more money in it this month!

 

There's a diagnostic code associated with the check engine light. A code reader tool is used to find it. The dealership should have pulled the code to help isolate the problem. Injectors can be bench tested.

 

Injector replaced I replaced the entire rail the truck is running well now. Next project is to tighten up the emergency brake so the light stops flickering.

 

Was it a bad injector or just the injector seals?

 

It may be flickering because you are low on brake fluid.
