Hi guys, on a 2014 Renault sandero 1.0T when got an issue tonight with trying to fit LED park lights(which didn't work) and after all this. The one standard park light is a disaster because only works when it wants to now and the the other issue is that the cluster doesn't light up anymore. I might think a fuse popped but Any ideas?
Thanks in advance

before you start putting jets in you first allow more air into the engine,this means dual carbs,4 branch manifolds,airflowed inlet ports,bigger inlet valves,and then we start on the exhaust system....janspeed engineering used to tune cars up to whatever power you could afford,they may still be doing this.....(just putting jets in is like having the choke 1/2 out......)
you could get a turbo engine from a scrapyard.....complete... and rebuild it for reliability. that would work.
