I have a couple problems: firstly it is a 2.5L manual transmission

1) My oil pressure gauge doesn't work in my car. What could be the problems i should check for in fixing this gauge?

2) I know this is stupid but i hit a pole a little while back while i was driving and texting at the same time(stupid i know) and my jeep still runs but it doesn't run very well. Between 1000 and 2500-3000 the acceleration is very jerky and very slow. What could be the problem with this?

If either of these can be answered, i appreciate it a lot

Thanks

 

Hey
I have the same model, engine and year as you do.
The oil pressure gauge in my jeep is doing the same thing. It registers a little when I accelerate, that's about it. Mechanic says it is probably a bad sensor or poor gauge.
As for rough idling, not sure.
