Ive got a ford transit swb 2ltr turbo on an 03 plate, ive had issues with it in the past losing power and the glow light flashing, that seemed to go away after a few miles so i put it down to a dirty connection. I went out this morning and started it up to find the accelerator pedal not working at first? plus it doesnt rev straight away seems a bit lethargic, yesterday it seem'd to have no go then woop it would shoot off (as much as a diesel turbo can) felt like really bad turbo lag, anyone had any issues similar etc or know what i could try ?
