When I accelerate quite hard, my car seems to bog down quite a bit and feels like its struggling. Also the exhaust seems alot louder, and when its bogging down the exhausts sounds like its coughing.
Any ideas whats up?

my 1.0 sometimes did this. It would just bog down as if it was going to stall, but when i came off the gas and then went back on, it was fine......no idea what the problem was though, but the em light never came on.

Ahh someone help me, my car goes about as fast as a milk float and sounds like a WW2 Bomber. Could it be the cat? EML comes on when cold aswell.

Dude when my AFM was playing up - i unpluged it and the car seemed to run right as rain. I got one off Wrightys SXi tho which fixed it in the long run.
When that EM light comes on its like finding out your cars got cancer. Just get it to Vaux and analysed - it will save you so much money in the long run.

Get it plugged into a diagnostic machine. As said above you could spend forever and a day trying to figure out which sensor has gone and replacing them unneccesarily.
Mine used to do it quite regularly. Had crankshaft sensor, AFM, ICV, o2 sensor in the past for other problems and it stopped it from doing the spluttering as often but my car still sometimes does it...

I wouldn't even waste your money at Vauxhall getting it diagnosed. They'll charge you between £35 and £50 for just that. Best bet is to carry out the "paperclip" test. Very handy and has saved me loads. Can do it on your drive and takes minutes. Visit this link...

Hope that helps.

Paperclip test doesn't work on some engines. I know it doesn't work on my 1.2 16v engine.
I dont always take it Vauxhall, I know a mechanic that has his own diagnostic equipment so that makes it alot cheaper.
