Be swapped inlet manifolds this weekend as I needed to change the inlet hose for a silicon one. The car starts but will not idle and sounds terrible . Any ideas?

Should say running issue lol

 

air leak?

 

forget to plug the maf back in?

 

or maf in backwards, i did this when i fitted my fmic. it would start and cut out straight away.
turned it around and it was fine.

 

Manifold is down tight, can't see where else there might be a leak

 

Maf is still connected up to the air filter , as it was before. Orange sticker facing towards the back of the car

 

Literally touch the throttle and it revs it's nuts off

 

check icv is not dirty or damaged

 

By the side of the throttle body?

 

yes mine packed up the day before i got my car mapped once. it will rev very high and sometimes not idle and cut out.
i dont know the classic set up but on the newage cars it has a rubber gasket that once removed will never go back in correctly as it has stretcehd through the heat etc and this needs replacing everytime as it causes an air leak and irratic idling

 

It's a normal gasket on the classic's, all looked fine when I took it off from one manifold to another. I'm drying off and warming up for a bit lol.

 

they look fine on the newage too but dont re seat correctly and leak.
mine revved to 2k and the idle was all over the place and cut out altogether sometimes

 

Thanks Tubbs. I also noticed for whatever reason both the Oil Pressure and Temp gauges were flashing as if not connected up correctly. Could a bad earth be responsible for both?

 

dunno its possible i guess the icv has an electrical plug on it

 

Thanks Tubbs, just went out and checked the ICV and found one of the bolts was only pinch tight. Did that up tight and it idles better.

Only thing is I can now hear the wiseco's slapping away

 

Were the pistons noisey before?

You really need to get it mapped, even a running in map on it.

 

Yeah they were. I took it up to see Simon a couple of weeks ago, the day before I managed to split the breather at the back of the standard inlet hose. i bodged it up and Simon looked at it before he even did a thing and advised against mapping it like that. Hence the need to change for a silicon inlet hose.

Once Simon's on the mend we'll arrange it again.
