Hello all,

I have been trying to solve this:

https://www.jaguarforums.com/forum/x...s-heavy-97101/

Basically car feels heavy on take of ocassionally and lacks power,sometimes shifts too long from first to second feels sluggish.

So I hooked up my OBD2 scanner to see what the sensors are doing. I tried to keep an eye mostly on the TPS, the fuel pressure sensor and the MAF.

The TPS at idle was mostly 4.3 sometimes it was 3.9 or 4.7 .After I filled up my gas tank it was consistently 5.1

The MAF at idle was .83 consistently

The fuel pressure sensor at idle constantly registered 54-56

Can anyone make anything out of those numbers?


Thanks
