when i start it up its reving at about 2000rpm now when i plug out the plug on the vacum at the throttle it sits at 1000rpm but it wont take the boot either way just keeps dying ( not cutting out tho ) now the only thing i changed when putting everthing back together was put on blitz dump valve and fitted group a coil. could either of these be the problem

 

c,mon guys it's breaking my heart here

 

ok wee bit more detail its very slow to initially start up pitter patters a lot then when it gets going it just sits at 2000rpm

 

Could be the water pump

but seriously could be the TPS ?

Dave.

 

is that throttle position sensor dave?

 

ok it starts fine now but it's still idling at bout 1500k is there an idle control screw?

 

yes but dont move it

you have a faulty sensor or wiring
