Actually, thinking about it, when the car is open loop, would it use the Long Term Trims?

 

[Shackeng]

This is going to get flaming confusing ...

[jamescdxv6]

this might sound pretty silly
but i am a novice lol

so how do u replace the trims

You dont - they are an internal calculation made by the ecu depending on other sensor readings...

[jamescdxv6]

any idea on what would solve the trim problem

thanks

Fixing the air leaks would be the first thing to start with

[jamescdxv6]

i take it that would be just checking all pipes over

and can u do this without car running

thanks

[Entwood]

One way of finding air leaks is to spray LIGHTLY with carb cleaner whilst the engine is running, spray lightly along vac pipes, plenum base, generally all around the engine..... but in a controlled manner .. don't just swamp the compartment.....  when the engine note changes it means some vac cleaner has been sucked in and burned as unmetered fuel, hence the change in engine note.

Closer examination of that area will eventually pinpoint the leak. Fix the leak, wipe the engine down with papertowel .. Voila .. fixed problem and a nice clean engine

[jamescdxv6]

thanks for that

only problem is my car wont start

is there any other way

thanks

[jamescdxv6]

just been told that the fuel pump and fuel filter could be the reason for car
not starting
would this not come up as a fault with a code

any ideas

[jamescdxv6]

just read an ad on fuel pump symptems of failure or on its way out

says engine misfire
starting intermitiadly
not starting

mine has done exactly this in that order
was misfiring so changed spark plugs
did start now and again
and now doesnt start lol

u think this is just a coincadence

[Martin_1962]

Still think crank sensor as the pulses drive the fuel pump.

Also one of the few thigs which will stop it even trying to start.

Do the pedal trick

[jamescdxv6]

ok will do

thanks for that

Check for spark & fuel when cranking the engine. No fuel and spark invariably equals failed crank sensor

[jamescdxv6]

how do u check for this mate

again not that clever when it comes to that stuff

cheers
