couple of LET questions

turbojay · 06-10-2008, 22:42

as myastra LT has been on the road for a week or so now i have noticed a few problems,

1. the engine management light is on when the car is first started then goes out after approx 10 mins of driving (basically when its hot)

2. when i first start car, mainly when its cold in the morning the engine seems to splutter when i pull off but again is fine when it warms up.

3. lastly the oil light keeps flickering on and off, (thinking its the sensor) as im using my old starter loom that was on my old engine and it was fine then or could it be the pump on its way out giving low oil pressure

thats about it, any help would be appreciated

thanks

1 and 2 could be related to the coolent temp sensor being on its way out, making it overfuel when cold n making it splutter.

3 i had this and it was because the little wire going to the sensor became unplugged, as soon as it was back in was fine

If the EML is on for 10 minutes read the codes!

mine does a similar thing in the morning when cold, splutters and hesitates, idles perfect, but doesnt want to go and will kangaroo until temp has come up a bit.

which coolant temp sensor should i be using, a geniune vauxhall one? if so how much are they?

As above, if the EML light is on, then ask the ecu why!

yeah exactly the same as what im getting, idles fine, just when i pull off.

chip i am going to do the test on the ecu to see what fault codes i get the weekend, just wanted to know if anyone had these probs before and new what could be wrong.

ive changed the coolant temp sensor, even tho both my sensors are giving of normal readings on the multimeter. it still does the same when cold. ive lived with it up until now but it is annoying.

im thinking of changing the air intake temp sensor in the tophat. ive already had my ecu code read twice with no faults comming up.

any other ideas of what else to change?

well im going to get a diagnosic on my car the weekend and if it aint the CTS then i will let you know what it is.

Are you aware of the paperclip test? www.topbuzz.co.uk go to the 'Info tech section', then scroll down to 'reading ECU fault codes'

That'll save you £50.

yes paperclip test FTW... when buying a new Coolant Temp Sensor make sure you allways get a genuine vauxhall one, last time i bought one it was £9.51 + vat. so about 11quid from vauxhall

Problem seems to have gotten worse, this morning it was struggling to idle properly until it warmed up. when moving off with a little throttle it wouldnt rev! was a bit of a nightmare to get going, but again ran fine when warmed up.

and yet you still havent bothered to flash the codes?

strange person

Got to agree with Chip here. Reading the codes take a couple of minutes and will give you an idea of the problem. The time it took you to post could have been spent with a paper clip.

guys ive already code read the ecu 3 times there are NO fault codes!!!!! im not an idiot do you not think i would of tried that already??!!

I had mistaken your thread crash and thought you were the original poster. Maybe starting your own thread would save future confusion.
