My idle has been dropping from 300-500 and up to 1200-1400 at a steady up and down up and down pattern. Changed the IAC because there bottom hole out of the two didn’t show the spring or anything so that’s replaced. MAF was I believe broken because when I unplugged it, the car went back to normal idle no signs of rough idle or anything. So I changed it, still rough idle however when I unplug it, car dies so that’s working. TPS was ok but I replaced it anyways still the same rough idle. NO CODES.
At the on position, I can hear the pumps prime, car drives normally 3+ gears with slight hesitation. 1-2 that’s where it takes a dive when I’m accelerating then back up. At idle I can hear the intake making like a scuba diving sound when you breathe and release air.
Possible vac leak I missed? If anyone has a diagram of all the lines so I can double check please.
Possible injectors or other fuel related? It drives almost perfect at 3-6 gear.
I did replace the MAF from SCT BA2400 to BA2600 (3 tuners so far has told me it is calibrated the same so my tune for the 2400 will be ok with the 2600 if the 2400 wasn’t wacky during tune. Which it wasn’t) i have a video of idle once everything mentioned above was done. Idk how to put it on here though
