Last night I washed down the engine and underneath the XJ. It started just fine and I drove home with no issues. Today it started ok but rev'd up and then went back down. At idle it wouldnt go below 1000rpm's. It runs fine, doesnt hesitate, or stumble, etc. And now it seems to be ok when I start it. It starts normal and idle is back to normal for now. Everything seems fine. Except when I try to pass someone or merge onto the freeway. I timed it on the way home from work tonight. Full throttle both times: 45mph to 65mph took 19 seconds. Then from 55 to 65mph took 10 seconds. Didnt kickdown but acted like it wanted to a few times. I turn the transmission shift switch a few times and it didnt matter nor did it matter after I exercised the shifter back and forth a few times. I thought maybe a vaccum leak but all my hoses seem to be on. I also thought maybe the TPS was starting to die. I did do a search and read some threads. Now I'd like to see what others might have to say.
