Hi , just wondering if you have any ideas. My Scooby has just started to play up,when I accelerate it seems fine but say I'm doing 50 and just accelerate a little it splutters like its running on 3cylinders or misfiring .any ides would be appreciated. My99 115000 miles.

 

Could be anything from a bad maf to a bad spark plug

see if the CEL has stored any codes by connecting the black connectors together under the steering wheel.
