c20let running rich?

[let_nova]

when idling etc the exhaust fumes are very noticable. theres no smoke etc when idling or driving, any ideas what could cause this? was thiking CTS? or maybe lambda?

Sensitive nose?

[let_nova]

nah, a car that was behind me commented aswell, could a wet fuel pump relay cause over fuelling?

[let_nova]

also using a lot more fuel!

Mine was overfueling, changed CTS, swapped airflow meter and ecu, checked all wiring, vacumm pipes, boost pipes.

I eventually was told to try Lambda and it's been perfect since.

[let_nova]

hmm, have a spare here, may try it. theres no way the fuel pump relay could cause it is there? was making a couple of weird noises earlier.

I got a new Genuine bosch one from autovaux for £67

[let_nova]

thanks, question, on the LET if the cars running unplugging the lambda, would it have an instand affect on the running?

[thegingerwhinger]

no way is it the fuel pump relay, air flow meter or lambda mate....

[let_nova]

thought that will cgange both tommorow.

cheers. no seen or heard from you in a while?

[Will F]

Yeahit wont be relay - they either work r they dont!

The only sensors that affect fuelling are lambda, cts and afm
