1997 Jeep Wrangler Idling Issues

1997 Jeep Wrangler

Can someone please check out these videos below and let me know what you think.

Give some gas and the RPMs drop near to zero (like it is going to stall) then fires back up. When driving it's a randomly jumpy when driving, maybe starts in second gear. Never stalls, just drops then goes back up.

Seemed to happen after battery replacement, but probably just coincidence.

****During the last hurricane in FL I tried to siphon gas from the gas tank and the metal piece at the end broke off and went into the tank. This was probably around OCT 2024. This issue just started occurring couple days ago after battery change (at least that is what my son said)

Waiting for new scan tool to arrive today as my other did not work. I did take it to Autozone and there scanner showed:
P0132
P0123
P0121
P0135

What I have done so far....
Clean the terminals on the battery cable ends just to make sure

I have cleaned the throttle body, IAC housing

Replaced the upstream o2 sensor

Bought a TPS from Oreilly but when i took the wire off this morning it fell apart all over the ground, so put the original back on

Ordered a new fuel pump, but man really want to make sure this is it before all the work involved for nothing.

Sounds to me like an issue with the TPS. Id purchase a quality replacement instead of one from O'Reilly. Mopar TPS is still available. Others may have different suggestions

Check all your vacuum lines especially the reservoir in the fender under the battery. I just did a MML and ended up with a disconnected EVAP line, high idle from the leak.

check manifold bolts, make sure they’re all torqued. Seems to me like a vacuum issue.

Appreciate all the replies, i will check these and let you know for sure.

I replaced the TPS with a Napa one ($100) and it seems better. Didn't want to wait for Mopar order. I am cautiously optimistic at this point... I will let you know if this is not the issue after driving for a while.

I'd highly recommend the NTK sensor,it's 37 bucks for a new one on Amazon

Mopar had NTK make them for the jeeps I believe,they for sure made the 02 sensors for our jeeps! 100 bucks is too much man!
