Misfiring, where to buy injectors?
My stupid as$ 4.0 is misfiring like no tomorrow. I started off with a misfire in cyl 3 when I bought it and it happened every now and then. Now I get misfires randomly in all cylinders. I went wheeling yesterday and the BDS Outback Adventure and I couldn't shut off the jeep on the trail or else it would misfire really bad. I think my injectors are going south. I looked up how much they costs and $60 each!!?? That's gonna costs around $500-$600 just to replace 6 injectors and a fuel rail? WTF That's insane.
Is there any place that sells a package deal of 6 injectors at a lower price or individually cheaper?
I am almost considering selling this p.o.s. because of how unreliable this stupid motor is. Sometimes I wish I stuck with my 2.5L cuz I beat the living hell out of that thing for four years and never a single issue or leak. It was bulletproof.

ebay... you can get a set of some that will give ya alittle boost in fuel milage also... they normally only go for around $100 on ebay... also junk yards... course you never know what your gonna get but most of the time injectors are unharmed... tried running some Lucas fuel injector cleaner yet? id do that first... if its bouncing around between cyl midfires then i really dont think its a injector... its gonna be something further up the line... like what actually sends the signal to the cyl to fire... say a distributor or coil or cam position sensor... something like that... all of which are cheaper then brand new injectors...

I don't have a distributor. Where are the coil packs located? Could the computer be going bad?

if the injectors where leaking it would cause you to have a slow start... because the fuel would run back down the lines and into the tank... so while your starting it fuel would have to draw all the way back up... its possible on the computer but they dont go out often... ive got a distributer and one single coil and havent worked on one any different so i couldnt tell ya where your coils are... just follow the plug wires... you should also have a cam position sensor somewhere on the motor then... mines in the distributor... possible cause also... actually Autozone can test just about any sensor on your jeep for free if you pull it... they have the equipment to anyway... finding someone that knows how to use it is a different story...

Get new spark plugs and wires first. I had bought some E3 spark plugs and for 3-4 months they worked great then they went to ****. It ran like yours. Then with new Champion plugs and wires I thought I got a new engine.

Cherokee 4.0, I'm not sure if your injectors are the same as mine. I have a 2001 and from what I've seen online when lookin to buy injectors is there are different injectors for particular years.

$20 for 8 of them
I bought 8 19# ford injectors for $30 shipped. I got out bid on E-bay and the seller gave me a 2nd chance offer for my top bid. I'll look for there store name and pm it to anyone who wants it. If anybody wants to buy the remaining 2 injectors from me pm me about that also.

does your model have a crankshaft position sensor? it would be located on top of the tranny by the bell housing. most jeeps dont have timing adjustments. that sensor controls the timing.

I think these are correct I wrote them down when is was reaserching for my jeep. I think I got them off a forum or from www.go.jeep-xj.info this guy at goJeep has so much info for everybody on XJ's and jeeps that somebody should give him an award or something. Hope it helps.
