Coming hone from seeing my kids and as I am getting onto the highway, a guy changed into my lane, so I floored it. Engine revved to 4500 and would not go any higher, car started slowing down like it was coasting, so I let up all the way and pressed it just slightly and car started going again.
Well 8-10 miles later and I am going down a hill and car felt like it came out of gear a time or 2 and thought it was my imagination till I pressed the peddle again when I hit the bottom of the hill. Car would not rev past 2k rpm's and I could feel the engine cutting out and in, so I decided to pull over and I got down into 3rd gear and the car run good, slipped it into neutral and car revved up to about 53-5400 before I let off. Pulled over and turned the car off, waited about 3-4 minutes and pulled back into traffic and car ran good for 8-10 miles and then did the same thing, pulled over, turned it off and then restarted, did this twice more and than ran perfect the rest of the way home.

First I thought the torque convertor was going bad, then fuel pump, then MAF, the the kickdown solenoid (not sure what it is called on a Jag) and now I am just baffled.
Anybody have an idea??

I had another thread going, but it was convaluted, so I am starting another.

Thanks!!

 

Hi randyb When was the fuel filter last changed? Might be worth checking.

Cheers Al

 

This weekend, I bought the car from a dealer and they do not know any of the history.

 

Hi Randy,

I have the same issues with our Jaguar XJ8 here in Cape Canaveral. I have no clue but am searching for an answer and will share it here. I may go over to the Jaguar dealer on Merritt Island to get some help.
