Fuel Injector change for FE?

[pana]

Sounds fun. I think any multiple hole injector will be better than the single pintle style version. Let us know how it turns out.

Correction, they are EV6 style not EV14 style which means they are the same height as the EV1 (pintle) type.

If anyone is interested they are Bosch #0280156161 or Ford 3S4Z9F593AA. New they are like $75-$101, rebuilt about half that. Most junkyards don't know the difference and charge next to nothing like all the other injectors from everything else. These are PEZV versions of the car and available in California and "green states", optional in other states. Bright red in color.

A guy on the focaljet forum says that it is one of the only 12 hole injectors produced. When compared to the 4 holers in the Focus he swapped them into they caused a more consistent and smoother idle, apparently due to the better atomization. Power would be the same as peak flow is unchanged.

I put 4 hole injectors from a crown vic cop car on my 94 ford ranger 4-banger and saw atleast 2mpg average better... but who's to say my old ones with 150k on them were working perfectly so I 'm not sure if it was the style of the injectors or if one of my old ones were bad. Although, my CEL wasn't on before and now it comes on either under 1500 rpm in gear or over 4000 rpm in gear, but never while idling or between. either way it was a free ecomodding win since I didn't pay for the injectors.

The ones on our 136k mile 2001 4.0L Cherokee XJ are original, and of the one-hole type (I keep thinking we're talking about a privy: one-hole, four-hole . .) and I have been reading on upgrading to the EV-6 type. Thanks for the above discussion as it hasn't been clear on the Jeep boards if a solid mpg gain was being seen. Maybe is different than confirmed.

Smoothness alone is worth it to me, and of necessary help on the slightly rough XJ idle to keep the diagnostic tree shorter when problem-solving. This looks like a no-brainer to order up some new type Bosch injectors.

Please post results back if you do the swap on your jeep. The jeep board mods are predominatly aimed at power rather than FE. So, to see FE results would be great. Also, details details. Which injectors and how hard was it to swap them please. newbie 96 xj owner and determined to get 25 + mpg consistently from it.

The decision has been made to trade the Jeep. Seems I'm the only one who really likes it. (Cheap to buy, cheap to run, cheap to fix . . what's not to like?)

The discussions I read were on NAXJA. Here is a link to one. I'd recommend new over rebuilt, and take care in spec'ng the correct ones for your model year.

Good luck.
