Hi I would think it is the air temp sensor, it dose not come up on a code if wearing out, ecu thinks its cold air coming in, should read between 8oms to 10oms, tells ecu to use more fuel or not, the faster the engine the more it reads it faster is colder idle is warmer. P.s i bourght a resister of e-bay now mine 17% low on emissions. £1.50p.http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=170376231488&ssPageName=STRK:MEBDIX:IT

What value is this resistor and where do you solder it?

[rustym95]

It is 0.10 so withe the orig it makes between 15-20% risistance, just connect it any way, test the risistace when connected. Oh its the first one only 2 connecson points just b4 the MAF. , realy works

I have a question about this resistor enhancement, if it fools the cars ecu into thinking the outside temperature is higher than it actually is ( and it does because i tried it, live data said the outside temp was 65 degrees when it was about 20 degrees), how will that affect the car starting on a cold day???

[Andy H]

I may be wrong but I thought that the temperature displayed on the MID came from the sensor under the front bumper & that the air temperature used by the ECU came from the sensor after the air filter (or from the MAF on facelift cars)

I don't think there is any connection between the displayed temperature and the temperature used in the ECU calculations.

This resistor enhancement DOES fit to the MAF, in parallel with the one thats in there...
The displayed temperature i referred to was the temp from the ecu via live data ("My Naff Code Reader")

Oops, sorry. I should have engaged brain before going into print.

Ha ha, no worries, back to the original question tho'
How would that affect cold starting??

[Andy H]

If the add on resistor merely corrects a wrong reading then I would think it shouldn't have any effect. If it leaves the ECU thinking that the air is warmer than it actually is then only the person who set up the fuel maps can tell you.

The ECU might use the coolant temperature as well as air temperature so cold starting might not be too badly effected.

My preference would be to replace any faulty sensors with new genuine ones & not try to trick the ECU by messing with its input signals.

I have the instructions of were it go's, and it gose were i said it go's.

Five weeks now driving a Kia loan car...I want my Omega back 

[mark.adams]

Still no idea why the emissions are high???

[TonyBrister]

No, can't be much left to test.....

Hi Tony, any further forward yet? :-?

20th of October now and still no cure. I just don.t know what to do now..
