So my engine light has been going on and off now for 3000 miles but with no symptoms. But yesterday the EPC light came on too. The engine is stuttering. You can really feel it when reversing. I think its something to do with air flow. Are there any places open Sunday in Wolves area?
Engine starts ok but you can feel it eunning awkward and exhaust stutters too
Research online may suggest MAF issue.or.vacuum
Where are these under.bonnet?

Ideally you need a fault code scan first of all, have a look at the map link in my signature and see if anyone is near you with vcds to scan.
