MX5 Mk2.5 holding back - but runs better on Super Unleaded
Discussion
Hello Guys,
I know Super Unleaded makes no real difference to the MX% Mk2.5 as its such a basic car which does not make use of high Octane fuels.
But recently my MX5 feels like it is holding back, and not easy to drive around town.
I put some Sainsburys Super Unleaded (97 ron) in it 4 days ago to see if it would help and now the car runs much, much better.
Its easier to start, feels much more responsive, lots more power.
Would this indicate a problem somewhere? Maybe its running lean? Problem Fuel Injectors? Timing maybe?
It has been serviced recently back in July, (new spark plugs, ht leads, coil pack, fuel filter, maf cleaned etc)
Any ideas please.
Thanks,
Rob
