My s2 engine is running very lumpy then stalling after a short time, ive put new plugs in and checked all the plugs are on the inlet ok, it was overfueling before but doesnt seem to be now, anyone got any ideas? and by the way, its following an engine and loom transplant from a running s2

 

could be down to the air fuel ratio if it was running rich & been adjusted wrong???

or a cold start valve sticking and flooding the engine when its not needed???or vice versa,, if its not plugged in ,,,,check it

try running with the cold start valve underneath the back of the inlet unplugged & see how it is then,,, or plug it in if its not lugged in

 

Thats the blue plug?, mixture hasnt been touched at all and the car used to run sweet as, will unplug the cold start tommorow and try it, any more suggestions?

 

double check it is plugged in & it would have the same effect if its unplugged

 

Its defo not unplugged cus i checked em all to see if everything was plugged in right and it was

 

ah and it runs better above 2500

 

is the throttle butterfly clean of dirt, etc as it could cause lumpy tick over due to it being partially open,,,, or check or swap the tps incase its faulty

all worth a try as there cheap & easy to try,,,,

im no mechanic mind
