Had two posts on this already and still no luck!

Car won't idle it backfires and is starting too smoke and smell of fuel!

Someone said its an air leak but checked the pipes, seem fine!

Replaced;

crank sensor
sensor in the thermostat
ignition pack
plugs
MAP sensor
throttle control sensor

leads are in good condition.

Plugs are going black just by starting it up but they are dry so im guessing its overfuelling! What could cause this?

It starts to smell of petrol now aswell so thinking thats the problem! Im going to change the fuel filter to see if that helps!

What else should i change/check? Its an xr3i EFI

 

Water temp sensor mate

 

Is this a common cause of overfuelling? Im having issues with my ka rst and someone did suggest that be changed......

Water temp sensor is the one in the thermostat housing, 29mm white plug right?

I got hold of a good second hand one but dosnt seem to of cured the problem!

 

Anyone.....

 

is the fuel pressure correct?

 

Im not sure. It hasnt been messed with so id imagine its okay.

Im running out of ideas of what to try next!

All the sensors were from the scrap yard off an xr2i. It was completly standard in mint condition, it had been stolen so i imagine they are in good condition!

Any ideas really would be gratefull

 

Ideas......

 

Could it only be running on 3 cylinders?

 

Had my car at the garage for a while and replaced the intake part of the manifold where the mixture screw is (the bit where the tps is)

It ran fine from cold ticked over fine revs went up and down cleanly etc

So i drove it home got half mile down the road and it started badly misfiring! Just got it home and it won't rev and idles rough and stalls again! Also stinks of fuel!

What can i try next? Really getting too me now! Even considering just getting another engine!

 

Anyone?
