gents ive been having a real bad idle, hunting up and down, running real crap

now I pulled the hose of the inlet manifold the one that goes to the map sensor and instantly it starts running perfect ?

what is that indicating please ?

Thanks Glen

 

ISCV, take out and clean with carb cleaner

 

done that mate and also bought a new one tried that no change

 

the blue water temperature sensor or TPS

 

have got a new blue temp sensor here mate, will get that in asap, the TPS was working perfect prior to fitting my new motor, im strugglin with this one

 

anyone help ?

 

hmmm, it is a 3 bar map sensor isn't it, and not the std escos 2.5 bar one... if the chip is expecting to see x.x volts at idle and is actually getting y.x volts until you take the pipe off and then it just happens to read x.x by fluke, ?

has it got a vent to atmosphere dump valve?

 

hi dave yes its a stage 3, with 3 bar map sensor

and it does have a VTA ?

cheers for the assistance again

 

just try diconecting the vac line off the top of the DV, and put a small bolt in the end ot the pipe to block it, see if that stabalises the idle....
