i got a 91 prelude si 2.1 i have a fuel pressure reg intake headers and exhaust. i start my car and if i blip my gas pedal it boggs out like as if it was to stall sometimes it does. i thought it was cause of my fuel filter changed it same ****. i think it is cause of the commando flow fuel pressure regulator i have it at stock psi still does it it also boggs out when iam in high rpm's. anybody have this problem or know what to do

 

Try your stock FPR. It could be your command flow is flowing quite a bit more fuel, but at the same psi. what do your plugs look like? you may even be running lean high end.

 

NAH THEY ARE NORMAL A LITTLE BLACK BUT PRELUDES RUN HOT SO ITS NORMAL I HEARD IT CAN BE MY TEMPERATURE CONTROL I DONT KNOW WHAT IT IS. IAM GOING TO PUT THE STOCK FUEL PRESSURE REGULATOR ON. NOW I HAVE TO BUY ONE CAUSE U HAVE TO CUT THE STOCK ONE FOR THE COMMANDO FLOW. DO U KNOW IF A 98 ACCOROD FPR FITS
