just fired the car up after its rebuild and it seems to be ticking over @ 3500rpm WTF is going on?

 

bolt missing from throttle cable bracket? TPS adjusted wrongly?

Try unplugging ISCV, if speed doesnt drop to idle, you have a BIG airleak.

 

Seen that before!!

 

It does seem like a air leak - the bolt is def in i can remember putting it in

 

THE? Theres two

 

One was a stud and one was a bolt i was just sat thinking i don't know if we put the bolt under the throttle body that goes through the bracket that goes to the engine mount do you think that would cause it????

 

im confused

 

no change there then...lol

 

dont worry man itll be sorted tommorow, hopefully.then i cant take any more parts of your motor

 

is that after you knick me banjo bolt for the power steering pump

 

no i couldnt be that bad,............could i ?

 

im going to drop my block out as soon as yours is finished anyhow so i will be dropping the fluid to put some fresh in

 

well if you insist lol.. im going out for a few pints ill see you in the morn

 

No, definately not pal. Havent adjusted the idle speed screw have you whilst it was all off? Maybe cleaned the tracts out?

 

Right i unplugged iscv and the revs dropped to normal,so then i took it out and sprayed loads of carb cleaner in and put it back together but it still hasnt solved it. help!!!

 

...your ISCV is fucked.

 

but it was ok before the rebuild

 

Throttle position sensor is incorrectly adjusted is my 1st guess then.

 

but the throttle position sensor hasnt been touched at all

 

Is the phase and crank sensor plugs the correct way round you have not got them crossed have you ?



Regards Doug.

 

What cossie is it? what ecu and TPS?

The plug fix simply proves teh ECU is sending voltage to teh valve, so it is being told either:

1) The engines cold.
2) The throttles open.
3) The engine speed is high.

The above scenarios all send a drive signal to the valve. All i can think of top of my head pal. If its 2wd, you can unplug the TPS and see if it helps, if it does, the signal error is there...

Just off out to eat so will be a while before i reply....

 

Good point DOOOGLAS... L8 will still run if Phase and knock black plugs are wrong way round. Unsure if L1 & 6 will though...

 

the phase sensor hasnt been touched as it was already brand new but i did change crank sensor,but it can only be olugged in one way cant it?

 

its a 2wd saff runing l6 ecu

 

Seems unliklely as its doing exactly what you would expect a properly working one to do.

Id say thats the least likely thing to be wrong.

 

No if the engine has been out check that you have the plugs the correct way saw this last week on a saff the plugs were crossed and it had high idle worth checking 2 mins work then i sudjest if that dont work listen to what stu is saying Mr knowledge

 

yes each plug only goes on one way

its putting the two plugs on each others sensor that is the risk

 

what do you mean plugs? sorry to sound thick

 

Sorry i correct myself Knock sensor and crank sensor NOT PHASE the two multi plugs are situated next to the distributor . lol

 

The penny has dropped...... i think i know what you mean i will check tommorow

 

Infact on reflection no it cant be the ISCV I was just thinkin about my situation when i had this...but it was anti lag valves not iscv

 

Hello i just been down garage to check i can see the plug for the crank sensor and the one to the dizzy but no more? were is the knock sensor situated as i car'nt remember seeing one when i had the engine out (COSSIEGREG'S CAR IS IN MY GARAGE) just incase you were wondering why i am repleying

 

anyone?
