Been trying to nail this one down for a bit but time to ask for help

On occasion after sitting a few days or even more rare over night, i've had issues with accelleration (misses perhaps?)...

Some accelleration in low rpm, but if I get over 2k rpm it will backfire even after the engine has come up to temp. This usually resolves itself fairly quickly then everything is back to normal (for a rover anyway)...

No codes are ever thrown, but it is frustrating.


I replaced the plugs & wires (8mm magnacore) when I started working on the truck a bit over a year ago.

I see it about once a week on average, current temps are 20-40's I don't recall it happening during the summer/fall


well can I be any more vague? ... just looking for suggestions on things to look for

 

Sounds fuel related. I'm sure someone with more Disco experience will chime in...

 

You got an ultra gauge or live data scanner?

Temp sender, fuel temp, intake air temp, TPS, IACV dirty

 

Got bluetooth adaptor, i'll add those to logging to see if anything is off.

 

First thing in morning , cold engine all temps senders should be ambient till you start engine

TPS is usually around 11.8 to 12.3 should be a steady #

 

K, yeah another day that everything seems fine... Thinkin its usually afterthe weekend when it sits an extra day, will log till I see something.
