Looking for guidance to an issue on my sons 2010 1.4 8v Punto Evo with 62k on clock. Vehicle has been sat for around 9 months. Just changed plugs and air filter.... oil had been done just before being laid up. Car drives perfectly around town.. spritely and as would be expected. However get it onto a faster road either flat or up hill and the vehicle is toiling, spluttering / stuttering and running out of puff.
Thought may have fuel starvation from contamination, rust from lay up, but no codes on daig.... idea was to change fuel filter but apparently lifetime filter I am told? Could be clogged injectors...which will now run application through fuel to clean/clear.. but then would I get the drive round town I am getting?
Do have a EML issue currently as a result of a start stop / neutral position sensor re-learning fault....but cannot see this causing limp mode
Any guidance, solutions, thoughts greatly appreciated.
TIA
