After looking around for a local mk2/3 polo, I settled for this 6n, 1999, 93k, some service history, its a 1.0 so no electric windows or anything. The seats are grotty, the windows are stiff as fuck to wind up, and the engine, once warmed up doesn't idle properly, so I'm guessing lambda sensor maybe? I've put her on coilovers and should be doing a chassis notch this weekend, got loads more plans for her but just haven't got the money as I'm only an apprentice :( so it will be a long term project haha! I don't have any pictures to upload at the moment but ill get some up soon :)

I changed my lambda, made no difference to idle except improve mpg. Lumpy idle on these is most likely a dirty throttle body or timing.

I took my throttle body off and cleaned it as it was oily, it now runs much better now, thanks for the tip
