I was driving around in 4th gear about 30 mph, and the check engine light came on, it revved lumpy and when I went to accelerate it wouldn't do anything, it last a couple of seconds, and it has been okay since,any ideas?

 

Mate similar to yours and was engine dead light six grand later and car is due back next week!! my advice is get it looked at asap or pm Tony Burns on here he seems to no his stuff
