my car point blank refuses to.

itl start up tick over for 5 - 10 secs. cough splutter and die. fookin typical. 2 days before knockhill.

the idle air control valve is disconnected and the idle screw is nearly right in. worked fine like this for months.

any ideas folks???????????

vroooom ptssssh

Should of found the problem when you had to do that to make it run properly first time

Hope you fix it before knockhill, be good to see you and the car there

tonyturbo

i know. its the idle air control valve that was sticking but uv got to take inlet etc of to get it off. bit of a mare to say the least. doubt i'l be at knockhill now.

Chrissy_bwoy

try the air charge temp sensor, mine did exactly that and it was that that caused it

vroooom ptssssh

hope you can fix it in time Tony !! either that or keep the revs up all the way there, its motorway mostly

tonyturbo

believe me the revs would have been up anyway. regardless. bought a new act sensor from ford. wrong 1. its what ford list as a act sensor for a frst. deffo not right.

tonyturbo

ticks over perfectly when cold. just took it out and ragged fook out of it just to see if it wanted to cure itself. goes like fook. leaves black marks all over the place. the odd brown one to i must add.

Hello....has it been setup?

tonyturbo

nope. if that was the problem it would have done it since the start. has been fine for 5oo miles. why would it decide to fuck up now?

vroooom ptssssh

aah but its been fine for 500 miles with disco'd air flow thingy and idle speed screw adjusted right in

coolant temp sensor if it ticks over fine from cold and not when warm

tonyturbo

put my original xr3i ofac ecu back in and hey presto. ticks over like a dream. is it ok to run it like this??????

idle air control valve removed completely as well now.

Ginge !

erm, did you swop the pins when ya changed the ecu

and where did ya get a ofac xr3i evu from

also what mapsensor ya using

infact run through exactly what ya have done to the car to run it on efi !!!!!

whats been fitted ect

Ginge !

whats the old bill got to do with this rudey

tonyturbo

done fook all to run it on efi mate. its a 90 spec xr3i. swapped to ofab just. pins were changed, map sensor was changed, ecu was changed.

this is fook all to do with it tho. its ran fine for long enough.

tonyturbo

bttt

When you start a car the first few seconds is very rich due to the after start fuel enrichment.
If your ecu does not fuel correctly (faulty sensor etc) the afterstart enrichment might be allowing it to run.

al have a fook around with sensors tomorrow

tonyturbo

if i disconnect the potentiometer it runs bang on.

PhilM

Throttle pot i assume? Looks like you may have found your problem! Try a new un

tonyturbo

potentiometer not throttle pot.

the potentiometer adjusts the emisions etc.

tonyturbo

the car was put on the rollers at AVA when it was first running (mar 04) just to check fueling etc. obviously couldnt run it up much as it had basically no miles on it. they said then that it was safe to use after they checked it. so it has been set up to a certain degree. in approx 10-12 weeks i hope to have it mapped and complete at msd. cheers for the concern. i think i have done well considering i'm a formwork joiner to trade.
