i have an odd issue with my car i have a random cut, when the car is hot i have a problem where the car will cut out, i thought it was the BOV cause it initially got this when changing gears after the BOV went off, so i tightened it right up and it seems to go away for a bit, i drove it from my place to QR about 1 hour with no problems. went out for my first run and when getting to 4000rpm i had the cut again, this happened about three times on my warm up lap but cleared up and was fine for the rest of the session.
now i go to start it up for the next session the car starts and then cuts out and stalls fire it up again and all is good, take it out for the warm up lap and it cuts out again at 4000rpm but then clears up and no problems again once the car is up to 85 degrees. same thing happens for the 3rd session. starts then dies and then fires again without a problem.
drive the car home and now i'm getting this cut when ever i give the car a bit, also happened when going up a hill and making a tight turn. anyway parked the car at home take it out the next day and all is ok.
the odd thing is the car was on the dyno the day before fuel pressure where good afr where rich but that is what i expected.
so if anyone has any ideas please let me know, i'm leaning towards fuel pump as it started to make more noise after the track day however it is now quiet. the only other thing i could think it is, is AFM but i'm at a loss. just wondering if anyone else has had a simliar issue?
