I have a s2 RST and have a slightly annoying fault. when the car is at normal temprature, and i start to accelerate, say from a junction when i lift off the throttle and press the clutch in the revs waver between 850 to 1000 rpm and then cuts out. It also does it on over run when approaching a stop. Does any one have an idea.

 

has it got a dump valve?

 

That shouldnt make a difference if its a sealed dump vavle?

I had the same problem on my cvh 1.4 before i had the turbo lump, you find yourself coming upto lights, pressing both the brake and the eccelerate together, cuz if you do this, it dont cut out .. am i right?

 

It has got a baily piston type with the twin piston type thingy.

 

check the spring hasn,t snapped at the top of the valve,this happened to me mates,what happened was the spring snapped and got stuck between the piston and the casing causing an air leak,check for air leaks elsewhere also

 

I have taken dump valve off and it still has the same problem cant seem to find any air leaks any where. any ideas any one.

 

i hadthe same problem on my old rst, it needed a set up. is your car chipped?

 

Not as yet, ive got a funny feeling it might be over fuelling as it likes a drink, might av to get a diagnostic check done.

 

their is no diagnostic porn on an rst is the

 

When i rebuilt my engine my car was doing the same, turned out to be the fuel mixture (too weak/lean). Adjusted the mixture now its fine.
