My wife’s daily drive has been giving problems for a while now, and as it’s failing all the time and the MOT is due I thought it time to fix it, how difficult can it be, bug...r me, it’s a pain in the rear end. I posted this on the jag forum with out joy.
This is now stupid :-)
For the last few months I’ve had both codes, so the time has come to resolve it, so far no joy, what have I done so far, the car also has a poor idle and has got worse from year one. No other error codes. Jaguar looked at the car 3 times over the years to find the poor idle and failed. It’s now at the point it needs fixing.
changed the maf
checked for vacuum leak, used smoke and pressure No leaks detacted
striped the manifold off and replaces the O rings around the pvc vacuum pipes
all cleaned and reassembled
cleared faults, disconnected he battery, after five mins both codes back
the car runs on LPG and petrol, I get the fault on both fuels, it runs 5% petrol while on gas.
Smoke tested again, nothing,
ok, mainfold off again and bit the bullet and removed the Lower manifold as well, it’s very messy, but the seals are good. Hope so as no smoke leak.
All ideas welcome, still in a thousand pieces, so anything else to check before putting the manifolds back together.
The bit that’s confusing me is both code, left and right bank lean, yet maf and vacuum seem ok. There is one other sensor in the inlet the map, is this next..
Thankyou for looking.
I just need this done so I can move back onto my pop.
smoke pot worked well..
