CEL? If there is, pull the code. If not, check simple first. Like vacuum hoses that are lacerated or cracked. Could be the MAF, (AFM in your case), dirty IACV, bad IACV, dirty TB, but also could be a fuel starvation issue. Like the fuel pump ECU, dirty injectors. There is a 12v fuel ECU mod. It bypasses the fuel pump ECU. PM me if you need the link to the DIY. YT doesn’t let me.
