Won’t drive without studdering
Okay so I’ve been working on my 97 4.0 and when I rev it won’t go past 3000 and then when I try to drive it it acts like either not enough fuel or to much air .. I did new distributor and plugs and plug wires and new 4 hole injectors and cold air intake and polished the throttle body and replaced the throttle positioning censor I’m at a holding point I don’t know what else to try

No not really I noticed right off the exhaust header is a good sized dent the exhaust don’t really smell strong even I’m pretty sure it’s the factory fuel pump so I think I will start with that

I can't get a link to post for some reason, but look up "97 XJ fuel pressure" on Google and you will find a spec thread with a response from CCKen.
Start there.

Don't buy any parts until you get the code. There is a way to do it without a reader. It requires you doing some tricks with the key. Google 97 XJ code key trick.
Also... check your fuel injection connections for full seat and proper order.
