1 Is there some reason you are ignoring the O2 sensor codes?

2) where did you get the injectors that lasted 2weeks?

3) What does the long term fuel trim look like?

/QUOTE]


yes wtf ?

if ts a downstream code it could be a blocked cat, if upstream could be several things, which are outlined when you look up the code on Google, gives a generic descriptor and a list of suggested faults and fixes.

All free.

come on, put us out of our misery and post this secret code (with descriptor please)

 

OP
in a previous thread it seems your fuel pressure is way low, did you ever fix that? What is the fuel pressure now?

After I changed the injector the fuel pressure went back up for 45ish

 

Back away from the keyboard?

I just haven’t got to the o2 sensors. I’m in high school and have to spend over $400 a month just in fuel
Im not to sure where the injectors are from. We both them a few years ago and never used them until now
Im not sure what the long term fuel trim looks like

 

No separate fuel filter on the 97+

 

400/month in fuel? As a high school student? Seems kinda up there. Maybe cut back on driving the jeep if you can and save some of that money to sort out this issue if possible. I'd start checking what things the others here have stated, starting with the easy bits, making sure floor mat isn't rolled under the pedal, clean your T-body, check the fuel filter to be safe. Stuff like that. Part of this sort of vehicle ownership on old jeeps is a process of elimination.

What is it with the fuel filter? As pointed out in the immediately preceding post 99 doesn't have a "fuel filter", they have a strainer in the tank on the pump. Good luck with that.
The OP has enough problems without being told repeatedly to maintain a part that doesn't exist.

 

I have to drive 40 miles a day just to school and back. Full tank with California prices is almost $100 and it only last about a week if that. I’ll start the process of elimination
Thank you

 

No front O2 sensor ?

unknown injectors ?

This is not a good recipe for fuel consumption or performance

I hardly know what to say,

get a used front O2 sensor and injectors from the same year wreck and put them in

 

The injectors are 4 hole injectors. I’m pretty sure we got them off ebay. I know I need o2 sensors. I’m not worried so much about the fuel mileage. The Jeep used to be able to cruise at 80 mph no problem at all. Now it barely cruises at 60. The o2 sensors have needed to be replace for a while. Way before the jeep started felling like it’s low on power

 

"new" injectors off ebay?

Likely cheap chinese junk knock-off pieces of crap then.

Probably a silly question but have you measured the compression on this thing?
