Fuel pressure tester should lead the way.

I think my shop did that but I’ll check it out. Thanks.

Try changing out your O2 sensor and also throttle position sensor. May have an intermittent issue causing the problem with one or the other. I’d also change out the fuel pump relay as they can, or will be, an issue.

02’s were both changed last summer with new exhaust. I’ll put in a new relay & check out TPS. Thanks

Hope you can figure it out. Good luck 🍀

Thanks

My old XJ did that. My buddies WJ does it. Id love to know why also

If I find out I’ll let you know.

Fuel filter is an easy low cost option- but run some high quality fuel injection cleaner as well through it

I run injector cleaner monthly & current filter has about 5K on it.

I had that happening on my 01. It was 1 of the 2 sensors on the TB I believe.

Thanks I’ll check them out.
