Hello,
Im new here and having a lot of problems with my ford ka van.
52 plate.

Long story so please bear with me.

About 14 mounths ago engine management light came on and car miss fireing. took it to garage. Ecu was the problem. this was sent off to be remapped. £600 later car back an all ok.

A couple of months ago car started juddering and engine management light came back on. Took it to garage and it was plugged in to diagnostic thing. It would not read anything apart from the airbag system. Took car away and drove it a couple of miles. Light went off and started running ok!

All was fine for about 6 weeks untill light came back on again. Back to garage. Again plugged in to diagnostics and this time would not read anything at all.

Car not running right, juddering and back fires a bit.

Garage at a loss what to do. Have rang place that remapped ecu. they say unlikely to be that again but if I send it back they will look at it for cost price.
Problem is garage say it will cost about £200 to take it apart and check connections and remove ecu if nec.

Really dont want to spend that sort of money on it as was going to change cars soon anyway. cant sell it as it is. Does any one of you knowledgeable ford people have any idea what this could be? Why wont diagnostics read the fault? Garage think maybe a loose connection but as above say it will cost £200 to look and thy might not find anything! PLEASE HELP! Really fed up with this now I know next to nothing about cars an thisis really getting me down now. No one seems abel eto sort it out
