S2000_Europe

Today I got a CEL.

I have a stock Comptech SC with AC. I do not pass of 4000 RPM and never WOT until I tunedthe car.

I was at the gas station, fill the tank and went to a shop (600 meters) to buy a magazine. I started the car again, then the CEL appeared. I look to the wide band sensor display 15-16:1 at ilde. I went back to home, before switch off the car ilde was 14.3-14.6.


I have realize that prior days tha car at ilde was always 13.5-14.2 a bit rich but after driving a bit the ilde went back to 14.6.


Thanks

and thought apart of reset the ECU?

check your gas cap..............make sure it is tight and many clicks are heard while tightening.............

I checked the Tap, was correct.

I reseted the ECU again and Started the car.

I left it at idle for 1 min, and no Cel, A/F ratio 14.6

then for 5 seconds A/F goes up to 15.5, started to bog, and comes down to 14.6 after this.


Will drive the car tihs night to see how it performs.

Pick up an OBDII scanner to figure out what code you're throwing. P0142 is the "lean" code if I remember correctly.

Need the code to go any futher.

Reseted the ECU again


Today I drove 200 km at above 100

It takes a couple of days for the ECU to display a CEL code after it's been reset.

I do not think so, today I drove 100 km more without any CEL. I cna belive that the ECU needs more than 300 kms to regonize an Error.
