Hi guys, honestly been about ten years since I've needed to post, but the time has come.
Last December I was lucky enough my very first lupo back on the road after rebuilding the gearbox etc however recently I noticed it was starting to struggle starting when the car had been sat over 12 hours or more. I got myself a copy of vcds and scanned the car multiple times and according to said software I have a P0300 code (random multiple misfire)
Sounds simple enough, or so I thought. So the tldr.
I've replaced spark plugs, HT leads, coul pack, two temp sensors, MAP sensor, fuel filter, general service etc blah blah and it still says I have the same problem. I honestly can't feel any misfire when driving the car and the starting thing has improved but still evidently something wrong. However the help I need from you guys is where to go next I know of certain things it could be from what I've seen online etc but if I'm being Frank I cannot afford to just keep buying parts on a whim anymore and was wondering if anyone could shed any light as to what they think it could be, oast experiences etc? Thankyou very much.
