My 98 has been doing this for awhile, and I am getting sick of not knowing what is causing it.
After a hot soak my xj will fall on its face for a few seconds then accelerate like normal. This happens usually when I am home for lunch and heading back to work, just as I am pulling out of my driveway and accelerating down the street. Sometimes if isn't as bad as others, but noticable. I once had what seemed like a backfire through the t-body.
I have tested most of the sensors (tps, cts, iat) and/or swapped them out (map, tps, O2, IAC), and check fuel pressure (no bleed down, normal pressure). I get no check engine light, and no stored codes. Being intermitant I really haven't gotten any results, but i assume it isn't one of the swapped sensors.
This doesn't sound like the vapor lock common on the 99-00 xj's to me, but I guess it could be.
Any ideas?
Thanks!
