Hi, any help would be greatly received..... escort van with a rs2000 conversion from a 1997 donor car.

The problem im having is the car wont idle as it should and is hunting slightly, will rev up but coughs n splutters but will complete the whole rev range, but if i try to drive away it just wants to cut out and coughs n splutters, i can coax it if i only very slighty touch the accelerator but as soon as i try to give it any throttle it just dies, checked the plugs and they was very black so i have put new plugs in and its still the same, idle control valve has been replaced with a brand new unit and the car is still the same..... what should i be looking for next, coil pack seems to be sparking all 4 plugs.. The van was driving perfect after the conversion, ideas where i should be heading?

Air leaks or split pipes if you say its hunting a bit.

Yeah someone else mentioned that, along with possible coils or fuel starvation, gonna go have a little tinker today so il check for leaks whilst im there.

AAASERVICES

Lol you could be right, ive had enough anyway and stuck it on ebay, someone else can sort it out.

AAASERVICES

having second thoughts about selling it........ any more ideas ?

I think you can rule out fuel starvation and/or the fuel filter.
Black spark plugs point to overfuelling. Maybe a defective sensor?
Get it on a diagnostic machine and check the sensor signals.

hi, ive got a odb11 reader, is there a odb point on these cars/vans as i thought they wasnt really around then, also what should i be looking for if they have, thanks

oldford

The 1997 engine you used does normally have a 16-pin diagnostic socket.
Whether your car has it? I have no idea about the model-year and what kind of engine was in it.
Did you use the wiring loom and ecu from the 1997 donor-car?
Did you also include the 16-pin connector and it's wiring?

AAASERVICES

Il have to call the guy later who done the engine transplant for me, definetly used the loom off the donor car but half my original loom is still in there so i think he spliced into it, im going to have look for the odb port in a minute, also ive been reading about the EDIS causing very similar problems so im going to try the direct earth solution just incase although i also think its a over fueling problem.

Hi, mine was hunting all the time & plugs were black it turned out to be over fuelling, hope this helps

AAASERVICES

how did you sort the problem mate, also any mechanics local fancy giving a little go over would be great.

A duff FPR could cause bad idle and sooty plugs. Coolant sensor could be faulty too.

Id go for fuel pressure regulator.

Hi sorry for the delay, my mechanic said my fuel pressure was sky high & he adjusted the octan by the black triangle 3pin plug on the inner wing just behind the air box on mine hope this helps you get it sorted.
