hello all just brought my self a s2 rs and when i brought it it was not running to well it seems to be really flat and when the boost comes in it starts to pop and fart

it has had changed
plugs
leads
dizzy
coil
fuel filter

but still the same can anyone help me as it is really bugging me

 

timing belt may have slipped.

was it running ok before you changed these parts or did you change these parts in an attempt to cure the problem ?

 

check the position of the dizzy with the head, try rotating it to retard/advance bout a mm at a time, but dont go thrashing it, you will know if it makes a difference from driving safely

 

tried to adjust the dizzy made no difference it only does it when it is warm i have found today i ran it when it was cold and it was fine but as soon as it is warm it plays up

 

overboosting, lack of fuel...more fuel when its cold from cold start valve so runs 'better'

get it set up by a pro !!!!

 

can the fuel pressure be adjusted on these?

 

Yes, but I wouldnt personally adjust it unless I knew what I was doing at the risk of my engine

 

how do you adjust the fuel pressure ?

also unplugged what i think is the boost temp sensor on the metal pipe that runs over the rocker cover and it only did it slightly and thn was fine

 

it is popping because it is running very lean. Probably too much boost for the fuel pressure - it needs looking at by a pro.

 

yeah turn the boost down and see how she runs, or like everyone else says get it on the RR and setup properly!

 

what boost are you running out of interest?

 

its only running at 4 psi

 

4psi??? Sounds like the Amal valve is dead, that will cut your boost right down to about 4psi i believe.

 

I had this years ago on my S1 when the Ford dealer overfilled with oil - Fine when cold but sick when warmed. Took another branch of dealership about a week to clean out and replace parts to remove excesses. It's OK though they are no longer a Ford dealer!

 

sayin that the oil is over the mark by a bit also the amal valve has been taken out

 

tried changing the fuel metreing unit and still the same

 

take it for a set up dude! will prob be cheaper by the time you have done buying parts that are not needed!

it will run great an go well

 

i no people keep sayin take it for a set up but what else could they do that i havent

 

needs to fix the problem really before it can be set up as cars not really drivable, as soon as you put the engine under load(as in pulling off slowly) it starts to miss and sounds like antilag poping and banging!
