Gday guys n girls, my 99 LS Blazer was running sweet, I parked it overnight then when I went to start it this morning,it cranked for ages and was a bitch to fire up. Once it fired up it'll idle in gear and park all good. But miss's and farts and stuffs around as soon as I crack it off idle...once it had heat in it, it'll start like normal but will still not rev up at all.
any ideas what may be the cause and what I can check? I'm in West Australia so it's hard to get info on it. All advice is hugely appreciated.
Cheers
