Help please! Rpms fall and engine turns off

[thesimpleS13]

hi nico, i've searched and searched, and couldn't really find a solution. I've had my SR20 for about a month and a half, it was pretty good, until i had the spark plugs and oil changed. After that, I went to drive it, and when I go above 30mph, and put it in neutral to slow down, the rpms fall to zero and the engine dies! Can someone please help me out? thanks

Check your BOV especially if it is not recirculated. Do you have a way of reading a/f ratio? Most common issue related to this is running rich, could be due to MAF, BOV, TPS, etc etc. We need more info before we can help to be honest.
