Does anyone know the range for ohms on the fuel injectors? I have a 2000 sport 4.0 v6. I have a misfiring cylinder #2. All of the injectors read around the 12 range except the #2 which kept reading at 180. What is a good range to be at?

 

12 Ohms at room temp.


180 Ohms is cause for rejection.

 

You sure that's a V6?

I'm kinda thinking you might not have a V6.

 

If it's reading 180 trash it ASAP. You can easily grab a replacement at any salvage yard or just upgrade them all as long as you are going to pull the rail anyway

 

Okay sounds like a plan thanks!

 

I'm 100% sure.

 

Ah......no. Inline straight 6, unless you've got some weird diesel.

 

That would be a rare bird indeed.

Does your engine look like this?



Cherokee 4.0 liter 6 cylinder

 

Just like that

 

That's what I expected, since that's the normal 4.0 six-banger that Jeeps have.

It's not a V6, it's an inline 6, sometimes referred to as an I-6. The cylinders are arranged in a straight line. It's not a V configuration. Not all 6 cylinders are V6s.

A V6 would look something like this:






A flat six (a.k.a pancake six) would look something like this:

 

Some folks have put Buick V6's in their Jeeps. So it's not that strange for someone to say they have V6 in their Jeep.

 

Power plants 101.

 

That's why I didn't say I was 100% certain.

Got it! Thanks for the correction and heads up!

 

It's a common mistake. No sweat.

The inline 6 has been a popular configuration over the years. Ford, Chevy, & Chrysler had long runs with inline 6 engines down through the years, and the Ford 300 is still being used in various kinds of non-road equipment. Can't meet smog requirements with those older engines, but they still get used quite a bit.
