when I'm accelerating I put the pedal all the way down to the floor and it kinda chokes itself out but doesn't kill it, what could be causing this?

 

Could be the Throttle Position Sensor or Ignition Coil.

 

Any check engine lights? what year is the Cherokee? when was the last tune up? You've got a handful of items that it could be, what CCKen mentioned is only the tip of the iceberg really but definitely some of the best places to start looking.

 

I've recently cleaned the throttle body and all the sensors with the appropriate cleaners, no check engine lights, 1996, hasn't had a tune up because it's ran fine for months with minor problems.

 

did your problem start before or after cleaning the throttle?

i would change plugs/wires/cap/rotor if you haven't done it. plugs are gernerally due every 30K on these

 

I cleaned the thottie a while back.

 

ok

 

I drove it tonight and it was horrible, kept bogging itself down until I let off the gas.

 

I've been dealing with a similar issue on my '92 for a while. Only thing left to change is the Stator inside the distributor (aka cam position sensor to some, though not correct sync sensor, pickup sensor, etc.) which I'll be replacing in the morning. I'll report back if the issue is gone after this.

I myself have already changed the cap, rotor, plugs, wires, coil, TPS, CPS, AIT, MAP, Temp Sensor (because the thing was staying in open loop), and even cleaned the IAC motor and throttle body along with replacing the throttle body gasket.

Thing is though, even if I have success after replacing my stator, you could replace the stator in your distributor and still have the problem. A lot of these components work in conjunction with each other and any one of them could be the problem. Start with the least expensive first.

 

Tune it up!!!

And, check fuel pressure. The fuel pump may by on it's last legs.

 

Yeah, I replaced mine twice, PLUS 2 FPRs. No luck in my case.

 

Which brand pump? It seems Airtex, Carter, and the PF something or another are absolute pieces of garbage.

 

Original was an OE Bosch - finally crapped out after 240-something miles... can't complain about that. Replaced it with a Carter - that was a mistake. It lasted all of 400 miles before it went back to doing the same thing that the Bosch was doing. So I pulled out the Carter and returned it and got another Bosch. Haven't had a fuel issue since. My fuel pressure had dropped to a whopping 19 PSI with the Carter. Worthless.

 

I would check your O2 Sensors wile you are at it as well.

 

I installed a Carter in my XJ four years ago and it has been working just fine.


Of course, the OP has a '96 so all bets are off.
