Hey Guys
So I recently brought an 08 FG turbo off a guy from facebook, stoked as with the car driving it home (about an hour and a half from where I live) I made the mistake of putting 91 in it I assumed it wouldnt be a problem bc I owned a ba xr6t prior and it ran fine on 91, anyway it drove home fine come the next day I drove it around in the morning to show one of my friends and when I went to leave I started the car and when I put it in Reverse it stalled all of a sudden (yes its Auto) to my frustration I ended up getting it to drive again and once I got it on the road I gave it a bit of sh*t and managed to get it to my friends house around the corner, I took off throttlebdy looked clean so I took the AFM out and cleaned that also put it all back together and it ran perfectly for about 5 mins then stalled again once it went under 1k rpm. I talked to the previous owner about it and he said hes only ever run 98 So I thought it may have been something to do with 91 so I filled the rest of the car up with 98 thinking it may have been tuned to just 98/95 and put some octane booster in there managed to get it to idle with out stalling then after about 20 mins I gave it a little rev and I noticed it started making a knocking kinda noise around 3k rpm. I brought an diagnostic reader and it doesnt come up with anything on there and im starting to freak out abit. Has anyone got any advice or how to go about fixing this and if it is a knock whats the best/cheapest way to fix that?
Cheers in advance
