he all i just bought a real nice escort cab rs turbo...it starts up first thing evry morning fine and drives perfect till it gets worm then it will start 2 miss fire and smoke,,,ill then leave it 4 about 30 mins then the car will start back up and drive fine after tha bu then repets it all the time...ive replaced the metering unit and fuel fillter but still the same problem..can any 1 hellp me plzzz

 

Could be ecu;

Does it overheat?

tried new plugs and leads?

Clean the dizzy?

Could be a number of things............

 

tryed leads,,new dizzy on ther aswell..car doesnt over heat wat so ever..it just missis as if its over fueling..im baffled lol

 

could be cold start valve sticking open??

 

I had this on an old xr2. Found that I had put the wrong type of fuel cap on and its wasnt letting enuf air in. Exact same symptons as what ur saying. I put one of those plastic caps on (not gud for mot tho!) and it ran great.

 

hi all..ive changed evrything i can think of now.. changed metering unit,plugs.leads,petrol fillter and coil..im going 2 try and put plastic petrol cap on it later and see wat happns..it so strage it runs perfect till temp pics up then it missis real bad as if its over fueling but starts bk up after about 30 mins and drives till it gets worm again..some 1 said something about the gap in the spark plugs 2 make sure ther rite..im well confuzed lol

 

sounds like its running to lean if anything its rich while the cold start valve is on,soon as tht cuts off its not got enuff fuel to run!

 

Howe do i sort tha out mate..IVE EVENM TRYD DISCONECTING THE COLD START 2 SEE IF IT WAS STICKING ON BUT IT WASNT. I REALY HOPE U CAN HELLP ME OUT AS THE CAR IS REALY GETTING ME DOWN AND IM THINKING ABOUT SELLING IT BU DUN REALY WANT 2 AS ITS A MINT H REG CABRIOLET IN TROPHY BLUE,,LOWERD ECT.......

 

i have a similar problem in that it's a bitch to start and then runs a little rich.
i've been told that the coolant temperature sensor will be knackered, which makes sense as the idle is high most of the time too.
give that a shot, it's located at the bottom of the inlet manifold.

 

Get it over to a tuners, or see if ya have any mobile tuners nearby. Plug it up to their machines and that should point out the problem.

Cost me Ł60 IIRC
