Rpm fault and lambda?
Rpm fault and lambda?
Hi, sometimes when you start car up it jumps up to 2000rpm for like 2 second and then goes back down and idles at 900-950 rpm, does anybody had same problem?? And once in 3weeks it has fault 'system to lean bank 1' I have put new lambda sensor on but still come on??? Any advice?? Thanks

Re: Rpm fault and lambda?
Which lambda sensor did you replace - pre or post cat?
You might want to look into replacing the coolant temperature sensor as this can cause behaviour like this.

I replaced first lambda, and I did replace coolant temp sensor but still does same!

Have you cleaned the throttle body and done a throttle body alignment?
Re: Rpm fault and lambda?
Yh I have done it before, but I didn't do it after I change lambda and temp sensor. I will try to clean throttle body tomorrow and reset it, thanks for help mate

Re: Rpm fault and lambda?
Also check the vacuum hose between the brake servo and the tb hasn’t split. This can cause some odd behaviour
Re: Rpm fault and lambda?

It’ll let too much air in as it’s a larger diameter. 1.0 needs a 1.0 TB
