Fookin car!!

[johnny_adidas]

ok now i am at a complete fukn loss!! this car is gona be the end of me i tell ya. some of you may remember i sent it in for a tech 1 earlier in the month because the ecu light was on but only ever showed code 12 when i papercliped it.
they came back with 2 faults. Air mass meter & coolant temp sensor.
fair enough, went off, ordered new ones.
arrived yesterday and i changed the AFM, started up car and everything was perfect, idling grand, revving was spot on, no flat spot and no ecu light. so turned everything off and went to change the cts. noticed the wires had been kinda pulled away so guessed that was where the problem lay. pulled them off anyhow. needed to pull the car forward so did and the ecu light came back so just thought it was cos i had pulled the cables out.
today,refitted new spade connectors at dinner time, then fitted the new cts.
filled with as much coolant as i cud then started her up but the fukn light is back on all the time.
irratic idle is back so had to adjust the throttle cable to stop it dropping below 1000 revs.
brought her for a spin, seems fine going through the gears and all, no flat spotting to be honest. but had to bring her home cos the coolant light came on. filled her up another bit and had to leave it to come back to work.
if the cts was causing the problems would it need to hav a proper level of coolant to work correctly?
has anyone had this same problems?
ive a funny feeling if i go to the opel garage again they are gona just say its the ecu but why wud the ecu just clap out like that all of a sudden.
really hoping someone can give a few suggestions and help me out.

disconnect battery for 1 hour when you can

when you remove the ground wire get into the car, turn on ignition (it wont turn on but put the key to that position) and press the brake pedal

replace lead after an hour making sure you have insulated those wires you speak of and make sure everything is connected before you do so

....we will go from there

thanks TFS. sorry dont know ur name. the battery was disconnected overnight until i had the cts refitted and the wires connected. then reconnected neg. will try as u suggest about the brake pedal though. might even run over now and it shud be long enough by time i finish work at half 5

[T.F.S.]

this is lamda equipped calibra?

[johnny_adidas]

yes. car is also decat. duno i that makes a diff. would lambda not log a fault if that was the problem

[T.F.S.]

i was wondering why te AFM was coming up as a fault when its not used on the lambda system


disconnect the AFM and then start the car (it might help us to determine where this fault is but iis clutching at straws....)

[johnny_adidas]

will do, back in a min.

[johnny_adidas]

ok.

afm connected. idle irractic to point where it drops to bout 700rpm n nearly cuts out.

afm disconnected. idles fine. around 900rpm

if the afm is new, would air flow be the problem? should i try disconnecting the air box and letting the engine run?

battery now also disconnected as suggested

[T.F.S.]

i bet that surprised ya didnt it eh?, little trick i learned in nam....


its one of two things.....its prob an air leak after the AFM and ill tell you the other reason after you have checked this

[johnny_adidas]

in after the afm im guessing u mean airbox side, not throttle body side?

oh and in case it makes a diff neither way got rid of the ecu light

[T.F.S.]

throttle body side, after the AFM

the leak will be from the AFM to the throttle body not the AFM to the airbox

[T.F.S.]

oh PS the light wont go out if it is getting more air then the AFM is registering (air being supplied via a leak)

[johnny_adidas]

nope i dont think there is any leak between those two. checked that whole black hose last week. then checked the join between the afm and power cap. only thing that may be is powercap gasket but ive got that as tight as i cud get it back down when i cleaned throttle body a month ago.
inlet manifold gasket?

[johnny_adidas]

what would be best way to find said leak if there is one? and can i ask what the second prob might be? or have i not earned enuf jedi points yet hehehe

what about the throttle body gasket, did you replace with a new one when you took it out to clean it or did you replace it
